Description

Technical Field

[0002] With the rapid development of science and technology, various mobile communication devices have appeared in people's work and life, such as mobile phones, tablet computers, walkie-talkies and other devices, and these mobile communication devices must be evaluated for RF performance before leaving the factory.

Therefore, how to detect the RF performance of mobile communication devices in different directions in a real network environment is a problem that people urgently need to solve.

[0051] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0053] Generally, the RF performance test can be performed by non-signaling coupling or OTA. Specifically, the platform tool can be used to control the signal transmission and reception between the mobile communication device and the coupling box to perform non-signaling coupling test. Alternatively, the mobile communication device to be tested is placed in a shielded room, and the technician controls the RF instrument to perform signal transmission and reception test to evaluate the air interface performance of the mobile communication device.

[0054] However, since the non-signaling coupling method in the related technology can only test the performance in a fixed direction, and the OTA method is a single signal environment, it cannot simulate the working conditions of various RF signals and noise superposition in the real network, and there are also problems such as cumbersome operation and low efficiency. Therefore, how to detect the RF performance of mobile communication devices in different directions in a real network environment is a problem that people urgently need to solve.

[0055] To this end, an embodiment of the present application provides a testing device, which is provided by setting a turntable, a position adjustment unit, and a driving unit, and installing the position adjustment unit on the turntable, and connecting the center point of the turntable to one end of the driving unit. The position adjustment unit is used to place the device under test, and adjust and fix the angle and position of the device under test on the turntable. The turntable is used to rotate around the center point under the drive of the driving unit to drive the device under test to rotate. It can ensure that the test is carried out directly in a real network environment, and the turntable and the device under test can be driven to rotate by the driving unit, and the placement posture of the device under test can be adjusted by the position adjustment unit, thereby achieving the effect of detecting the RF performance of the device under test in different directions.

[0056] The test device provided in the present application can be used to test radio frequency performance, and can be specifically used to evaluate or test the radio frequency performance of a mobile communication device in a real network environment. The embodiments of the present application do not limit this.

[0057] The testing device provided in the embodiment of the present application is exemplarily described below with reference to the accompanying drawings.

[0058] In one embodiment, Figure 1 As shown, a testing device is provided, which includes: a turntable 101 , a position adjustment unit 102 , and a driving unit 103 .

[0059] The position adjustment unit 102 is installed on the turntable 101 , and the center point of the turntable 101 is connected to one end of the driving unit 103 .

[0060] The position adjustment unit 102 is used to place the device under test and adjust the angle and position of the device under test on the turntable 101 .

[0061] The turntable 101 is used to rotate around the center point under the drive of the driving unit 103 to drive the device under test to rotate.

[0062] In this embodiment, the turntable 101 may be an insulator, for example, the turntable 101 may be made of a non-conductor such as wood or plastic.

[0063] The turntable 101 may be circular, or may be any possible shape such as rectangular, star-shaped, triangular, etc. The size of the turntable 101 may also be set according to actual needs, for example, the diameter of the turntable 101 may be 80 centimeters (cm). As long as the turntable 101 can maintain a certain balance when rotating, the embodiment of the present application does not limit this.

[0064] Generally, in order to prevent the driving unit 103 from blocking the signal of the device under test placed on the position adjustment unit 102, the position adjustment unit 102 and the driving unit 103 can be respectively arranged on two sides of the turntable 101. For example, the position adjustment unit 102 can be installed on the first side of the turntable 101, and the center point of the second side of the turntable 101 is connected to the driving unit 103, which is not limited in the embodiment of the present application.

[0065] In addition, the first surface of the turntable 101 may refer to a surface of the turntable 101 away from the driving unit 103, or may refer to a surface of the turntable 101 facing the RF signal source, or may refer to a surface of the turntable 101 for placing or fixing the device under test.

[0066] The second side of the turntable 101 may refer to a side of the turntable 101 close to the driving unit 103, or a side of the turntable 101 facing away from the RF signal source, or a side of the turntable 101 used to connect to the driving unit 103. This embodiment of the application does not limit this.

[0067] For example, when the testing device is placed horizontally on the ground, the first side of the turntable 101 may refer to a side of the turntable 101 away from the ground, and the second side may refer to a side of the turntable 101 close to the ground.

[0068] In this embodiment, the center point of the second surface of the turntable 101 may refer to the geometric center of the second surface, and the center point of the second surface coincides with the rotation axis of the turntable 101. In this way, it can be ensured that the turntable 101 can maintain balance when rotating.

[0069] In this embodiment, the position adjustment unit 102 may refer to a device for placing the device under test.

[0070] The angle and position of the device under test placed on the turntable 101 can be used to characterize the posture of the device under test.

[0071] For example, if the device under test is placed at a specific position of the position adjustment unit 102 at a specific angle, during the rotation of the turntable 101 , the device under test continues to maintain the specific angle and continues to be fixed at the specific position.

[0072] That is, unless the user or relevant technicians change the position and / or angle of the device under test on the position adjustment unit 102 through the position adjustment unit 102 , the position between the device under test and the turntable 101 remains unchanged.

[0073] In this embodiment, the device under test may refer to any mobile communication device that needs to be tested for radio frequency performance. The device under test may receive any possible electromagnetic waves and / or radio frequency signals in a real network environment, and may also emit corresponding electromagnetic waves and / or radio frequency signals.

[0074] In this embodiment, the driving unit 103 may refer to a device for driving the turntable 101 to rotate. The driving unit 103 may include a motor and a corresponding transmission device, which is not limited in this embodiment of the present application.

[0075] The turntable 101 may rotate in a clockwise direction or a counterclockwise direction, which is not limited in the embodiment of the present application.

[0076] It is understandable that, since the position adjustment unit 102 is mounted on the driving unit 103 , when the driving unit 103 drives the turntable 101 to rotate, the turntable 101 also drives the position adjustment unit 102 to rotate, thereby driving the device under test placed on the position adjustment unit 102 to rotate.

[0077] Generally speaking, since general mobile communication devices send and receive signals through antennas, and the radiation of antennas is directional, the working efficiency of antennas at different angles varies. Specifically, the working efficiency of antennas is higher in the direction perpendicular to the extension direction of the antenna, lower in the direction parallel to the extension direction of the antenna, and lowest in the direction parallel to the extension direction of the antenna.

[0078] It is worth noting that since the radio frequency signal is an electromagnetic wave, when the electromagnetic wave is directed toward a metal object, an induced current will be generated on the surface of the metal object due to electromagnetic induction. However, there is a certain resistance on the metal surface, which will produce a certain amount of heat loss. In this way, the problem of signal shielding will arise. However, the turntable 101 in this embodiment is an insulator, which can avoid the problem of signal shielding caused by electromagnetic induction, and ensure that the device under test can reliably and stably receive various radio frequency signals in the real network environment during the test process, thereby improving the reliability, stability and practicality of the test device.

[0079] It should be noted that in order to test the radio frequency performance of the device under test in different directions, it is necessary to adjust the position and / or angle of the device under test on the turntable 101 to perform multiple rounds of testing. This embodiment takes three rounds of testing as an example. The working principle of the test device provided in this embodiment is as follows:

[0080] Before testing, insert a SIM card into the device under test, set the device under test to flight mode, and enable the log capture function.

[0081] In the first round of testing, the device under test can be placed horizontally on the position adjustment unit 102, then the flight mode of the device under test can be turned off, and data transmission can be performed after the device under test registers the network (for example, the device under test can be used to watch videos or live broadcasts online). Then, the drive unit 103 drives the turntable 101 to rotate around the center point to drive the position adjustment unit 102 and the device under test placed on the position adjustment unit 102 to rotate. After continuous rotation for 3 minutes or other duration, the drive of the turntable 101 is stopped, and log capture is turned off.

[0082] In the second round of testing, the device under test can be placed vertically on the position adjustment unit 102, and then the flight mode of the device under test can be turned off, and data transmission can be performed after the device under test registers the network. Then, the drive unit 103 drives the turntable 101 to rotate around the center point to drive the position adjustment unit 102 and the device under test to rotate. After continuous rotation for 3 minutes or other time, the drive of the turntable 101 is stopped and log capture is turned off.

[0083] In the third round of testing, the device under test can be placed on the position adjustment unit 102 at an angle of 45° (or any other possible angle except the horizontal and vertical directions), and then the flight mode of the device under test is turned off, and data transmission is performed after the device under test registers the network. Then, the drive unit 103 drives the turntable 101 to rotate around the center point to drive the position adjustment unit 102 and the device under test to rotate. After continuous rotation for 3 minutes or other duration, the drive of the turntable 101 is stopped, and log capture is turned off.

[0084] Then, the logs captured through three rounds of tests can be used to analyze the RF performance of the device under test in different directions.

[0085] In addition, in a possible embodiment, after each of the three rounds of tests is completed, an additional round of tests may be added, and the newly added test differs from the previous round of tests only in the rotation speed of the turntable 101, and other parameters remain the same. In this way, the influence of the different moving speeds of the device under test on the RF performance of the device under test can also be tested.

[0086] In one embodiment, when the device under test is horizontally placed on the position adjustment unit 102, the device under test can also be directly placed on the turntable 101 without using the position adjustment unit 102 to fix the device under test. The specific adjustment can be made according to actual needs, and this embodiment of the application does not limit this.

[0087] It is worth noting that the test device provided in the embodiment of the present application includes a turntable 101, a position adjustment unit 102, and a drive unit 103. The position adjustment unit 102 is installed on the turntable 101, and the center point of the turntable 101 is connected to one end of the drive unit 101. Specifically, the device under test can be placed on the position adjustment unit 102, and the angle and / or position of the device under test on the turntable 101 can be adjusted by the position adjustment unit 102, and then the turntable 101 and the device under test can be driven by the drive unit 103 to rotate, so as to capture the log of receiving and sending RF signals during the rotation of the device under test and the RF performance test, and determine whether the RF performance of the device under test is normal through the log captured during the test.

[0088] Combined with the above working principle, it can be seen that by using the test device, after each adjustment of the placement angle and position of the device under test, the turntable 101 and the device under test can be driven to rotate to perform a round of RF performance testing. In this way, the RF performance of the device under test in different directions can be tested.

[0089] In addition, the test device provided in the embodiment of the present application has a simple structure, does not require the setting up of a dedicated test environment, can be directly placed in a real network environment for testing, and also has the advantages of simple operation, high test efficiency, and low cost.

[0090] In this way, it can be ensured that the test device can be tested directly in a real network environment, and the turntable 101 and the device under test can be driven to rotate through the driving unit 103, and the placement posture of the device under test can be adjusted through the position adjustment unit 102, thereby achieving the effect of detecting the RF performance of the device under test in different directions.

[0091] For a possible implementation, see Figure 2The driving unit 103 includes a driving shaft 1031 and a motor 1032 .

[0092] A first end of the driving shaft 1031 is connected to the center point, and a second end of the driving shaft 1031 is connected to the motor 1032 .

[0093] The motor 1032 is used to drive the driving shaft 1031 to rotate. The driving shaft 1031 is used to drive the rotating disk 101 to rotate around the center point under the drive of the motor 1032.

[0094] In this embodiment, the driving shaft 1031 may be a transmission rod, which is specifically used to transmit the torque output by the motor 1032 to the turntable 101, thereby driving the turntable 101 to rotate.

[0095] Furthermore, the drive shaft 1031 may be connected to the motor 1032 or the turntable 101 by any possible means such as a flange, a sleeve, a latch, etc., or the drive shaft 1031 may be directly fixedly connected to the turntable 101, which is not limited in the embodiment of the present application.

[0096] When the motor 1032 drives the drive shaft 1031 to rotate, and the drive shaft 1031 drives the turntable 101 to rotate, the turntable 101 can be kept rotating at a constant speed, for example, the rotation speed of the turntable 101 can be controlled at 3 revolutions per minute (r / min).

[0097] In this embodiment, the driving shaft 1031 may also be an insulator, for example, the driving shaft 1031 may be made of a non-conductor such as wood or plastic.

[0098] Moreover, the length of the driving shaft 1031 can be set to be relatively large, such as 80 cm. Specifically, the length of the driving shaft 1031 is greater than a preset length, which is the signal shielding radius of the driving unit 103 .

[0099] It should be noted that the motor 1032 in the drive unit 103 works based on the principle of electromagnetic induction. The motor 1032 generally includes corresponding stator windings and / or rotor windings, and even has a metal casing. Therefore, there will be a signal shielding area around the motor 1032 that can shield electromagnetic waves.

[0100] The signal shielding radius refers to the radius of the signal shielding area of ​​the motor 1032 .

[0101] In this way, not only can the torque output by the motor 1032 be transmitted to the turntable 101 through the driving shaft 1031 to drive the turntable 101 to rotate, but also, since the driving shaft 1031 having a length greater than a preset length is provided, the problem of the signal shielding of the metal parts in the driving unit 103 affecting the RF performance of the device under test can be avoided. In this way, the practicality and reliability of the test device can be improved.

[0102] In a possible implementation, see Figure 3 The driving unit 103 also includes a gearbox 1033 .

[0103] One end of the gearbox 1033 is connected to the motor 1032 , and the other end of the gearbox 1033 is connected to the second end of the driving shaft 1031 .

[0104] The gearbox 1033 is used to adjust the rotation speed of the drive shaft 1031 .

[0105] Specifically, the gearbox 1033 can enable the driving shaft 1031 to maintain a uniform rotation speed.

[0106] It is worth noting that the gearbox 1033 is generally located between the motor 1032 and the drive shaft 1031, and the gearbox 1033 is generally made of metal material, so there is also a signal shielding area around the gearbox 1033. In this case, the signal shielding radius refers to the radius after the signal shielding area of ​​the motor 1032 and the signal shielding area of ​​the gearbox 1033 are superimposed.

[0107] It is worth noting that the gearbox 1033 can control the rotation speed of the drive shaft 1031, thereby achieving the purpose of controlling the rotation speed of the turntable 101. In this way, it can be ensured that the turntable 101 and the device under test can maintain a uniform rotation speed during the test process, so as to avoid affecting the accuracy of the RF performance test results of the device under test due to the different rotation speeds of the device under test.

[0108] In a possible implementation, the position adjustment unit 102 is also used to place a comparison device.

[0109] The position adjustment unit 102 is specifically used to make the comparison device and the device under test form an axisymmetric relationship with the rotation axis of the rotating disk 101 as the center.

[0110] In this embodiment, the comparison device may be any device that has undergone a radio frequency performance test to ensure that the radio frequency performance is normal.

[0111] In this embodiment, the rotation axis of the turntable 101 is perpendicular to the first surface or the second surface of the turntable 101 and coincides with the center point of the turntable 101 .

[0112] It is worth noting that since the comparison device and the device under test are axially symmetrical with the axis of rotation of the turntable 101 as the center, it can be ensured that when the turntable 101 rotates, the angular velocity and linear velocity of the comparison device and the device under test are the same, thereby ensuring that the test environment of the comparison device and the device under test is the same.

[0113] In addition, since the test device provided in the embodiment of the present application is directly placed in a real network environment to test the RF performance, and the working conditions of the real network environment are very complex, setting a comparison device with normal RF performance as a control group can eliminate the abnormal test data caused by environmental problems.

[0114] In this way, the accuracy and reliability of the testing device can be further improved.

[0115] For a possible implementation, see Figure 4 , the position adjustment unit 102 includes a supporting device 1020 .

[0116] Two placement areas are provided on the supporting device 1020 .

[0117] In this embodiment, the two placement areas are used to place and fix the device under test and the comparison device, respectively. For example, the support device 1020 may be foam, and the two placement areas may be slots provided on the foam, and the slots may be provided in different shapes or angles according to actual needs.

[0118] In addition, foams with different grooves may be replaced as the supporting device 1020 in different test wheels, which is not limited in this embodiment of the present application.

[0119] In this embodiment, the distance between the two placement areas is greater than or equal to a preset distance. Moreover, the preset distance is a signal interference distance between the device under test and the comparison device, and generally the preset distance is 30 cm.

[0120] In one embodiment, see Figure 5 The supporting device 1020 may further include a first supporting component 1021 and a second supporting component 1022 .

[0121] The first supporting component 1021 and the second supporting component 1022 are not connected, and a placement area is respectively provided on the first supporting component 1021 and the second supporting component 1022 .

[0122] It is worth noting that, since certain electromagnetic interference will be generated during the process of the device under test and the comparison device receiving and transmitting radio frequency signals, thus affecting the radio frequency performance between each other. Therefore, the distance between the two placement areas is made greater than or equal to the preset distance, so that the distance between the device under test and the comparison device can be made greater than or equal to the signal interference distance between the device under test and the comparison device. In this way, the problem of the electromagnetic interference between the device under test and the comparison device affecting the test accuracy of the test device can be avoided.

[0123] It is worth mentioning that, continue to see Figure 4, taking the position adjustment unit 102 including the support device 1020 as an example for explanation, the working principle of the test device provided in this embodiment when the device to be tested and the comparison device are placed at the same time is as follows:

[0124] Before the test, SIM cards are inserted into the device under test and the comparison device, and both the device under test and the comparison device are set to flight mode and the log capture function is turned on.

[0125] See also Figure 4 (a) and (b) in Figure 4 (a) is a side view of the test device. Figure 4 (b) is a top view of the test device. In the first round of testing, the device under test and the comparison device can be placed horizontally on the position adjustment unit 102, and then the flight mode of the device under test and the comparison device can be turned off, and data transmission can be performed after the device under test and the comparison device register with the network. Then, the drive unit 103 drives the turntable 101 to rotate around the center point to drive the position adjustment unit 102, the device under test and the comparison device placed on the position adjustment unit 102 to rotate. After continuous rotation for 3 minutes or other duration, the drive of the turntable 101 to rotate is stopped, and log capture is turned off.

[0126] See also Figure 4 In (c), in the second round of testing, the device under test and the comparison device can be placed vertically on the position adjustment unit 102, and then the flight mode of the device under test and the comparison device can be turned off, and data transmission can be performed after the device under test and the comparison device register with the network. Then, the drive unit 103 drives the turntable 101 to rotate around the center point to drive the position adjustment unit 102, the device under test and the comparison device to rotate. After continuous rotation for 3 minutes or other duration, the drive of the turntable 101 is stopped, and log capture is turned off.

[0127] See also Figure 4 (d) in the third round of testing, the device under test and the comparison device can be placed on the position adjustment unit 102 at an angle of 45° (or any other possible angle except the horizontal and vertical directions), and then the flight mode of the device under test and the comparison device can be turned off, and data transmission can be performed after the device under test and the comparison device register with the network. Then, the drive unit 103 drives the turntable 101 to rotate around the center point to drive the position adjustment unit 102, the device under test and the comparison device to rotate. After continuous rotation for 3 minutes or other duration, the drive of the turntable 101 is stopped, and log capture is turned off.

[0128] Then, the logs captured through three rounds of tests can be used to analyze the RF performance of the device under test and the comparison device in different directions.

[0129] Specifically, since the RF performance of the comparison device is normal, if the logs captured in the three rounds of testing all show that the RF performance of the device under test and the comparison device is poor, it means that the network environment in the real network environment is poor, not the performance problem of the device under test. If any log captured in the three rounds of testing shows that the RF performance of the comparison device is normal and the RF performance of the device under test is poor, it means that the network environment in the real network environment is normal and there is a performance problem with the device under test.

[0130] That is, during the test, as long as the RF performance index of the device under test is close to or better than that of the comparison device, it means that the RF performance of the device under test is normal. Otherwise, it means that there is a problem with the RF performance of the device under test.

[0131] For a possible implementation, see Figure 6 The position adjustment unit 102 includes a first rotatable bracket 1023 and a second rotatable bracket 1024 .

[0132] The first rotatable bracket 1023 and the second rotatable bracket 1024 are fixed on the turntable 101 .

[0133] The first rotatable bracket 1023 is used to place the device under test and adjust the angle and position of the device under test on the turntable 101 .

[0134] The second rotatable bracket 1024 is used to place the comparison device and adjust the angle and position of the comparison device on the turntable 101 .

[0135] In this embodiment, the angle and position of the comparison device placed on the turntable 101 can be used to indicate the posture of the comparison device.

[0136] In this embodiment, the distance between the first rotatable bracket 1023 and the second rotatable bracket 1024 is greater than or equal to a preset distance.

[0137] The preset distance is a signal interference distance between the device under test and the comparison device.

[0138] Exemplarily, the first rotatable bracket 1023 and the second rotatable bracket 1024 may have an outer frame, and the rotatable brackets may be fixed on the turntable 101 by the outer frame, and the device under test and the comparison device may be placed on the central axis of the rotatable brackets by a clamp or a fixture.

[0139] In addition, the central shaft can be driven by a motor and can rotate 360°.

[0140] It is worth noting that, as mentioned above, making the distance between the first rotatable bracket 1023 and the second rotatable bracket 1024 greater than or equal to the preset distance can avoid the problem of the test accuracy of the test device being affected by the electromagnetic interference between the device under test and the comparison device.

[0141] Furthermore, since the central rotation axis of the first rotatable bracket 1023 and the second rotatable bracket 1024 can rotate 360°, the device under test and the comparison device can be adjusted to any angle for testing. In this way, the test device can cover more angles for testing, which can improve the flexibility and practicality of the test device.

[0142] In a possible manner, the testing device further includes a micro control unit.

[0143] The micro control unit is used to control the first rotatable bracket 1023 and the second rotatable bracket 1024 to rotate, so as to drive the device to be tested and the comparison device to rotate.

[0144] Exemplarily, the testing device may also include a motor for driving the first rotatable bracket 1023 and the second rotatable bracket 1024 to rotate. The microcontroller unit may specifically drive the first rotatable bracket 1023 and / or the second rotatable bracket 1024 to rotate by controlling the corresponding motors, thereby achieving the purpose of indirectly controlling the first rotatable bracket 1023 and / or the second rotatable bracket 1024.

[0145] It is worth noting that, since the microcontroller unit can control the rotation of the first rotatable bracket 1023 and the second rotatable bracket 1024, there is no need for the user or relevant technicians to manually adjust the posture of the device under test or the comparison device during the test process. In this way, the automation of the test device can be further realized.

[0146] For a possible implementation, see Figure 7 The position adjustment unit 102 includes a first stopper 1025 and a second stopper 1026 .

[0147] The first limiter 1025 is provided with a plurality of first limit slots, and the second limiter 1026 is provided with a plurality of second limit slots.

[0148] The first stopper 1025 and the second stopper 1026 are fixed on the turntable 101 .

[0149] Wherein, each first limit slot is used to place the device to be tested, and the opening position and inclination angle of each first limit slot are different.

[0150] Each second limit slot is used for placing the comparison device.

[0151] Furthermore, the minimum distance between each first limiting slot and each second limiting slot is greater than or equal to a preset distance.

[0152] In this embodiment, the first limiter 1025 and the second limiter 1026 may be made of insulating materials such as plastic, wood, or foam, which is not limited in this embodiment of the present application.

[0153] For example, since the position adjustment unit 102 can make the comparison device and the device under test form an axisymmetric relationship with the rotation axis of the rotating disk 101 as the center, see Figure 7 The first stopper 1025 is provided with four first stopper slots at different positions and angles, and therefore, the second stopper 1026 is also provided with four second stopper slots at different positions and angles. Figure 7 It can be seen that the opening position and the inclination angle of each second limiting slot correspond to the opening position and the inclination angle of each first limiting slot.

[0154] In this embodiment, the minimum distance between each first limit card slot and each second limit card slot is greater than or equal to the preset distance, which specifically means that the distance between the closest first limit card slot and the second limit card slot is greater than or equal to the preset distance.

[0155] For example, Figure 7 The distance between the rightmost first limit slot in the first limiter 1025 and the leftmost second limit slot in the second limiter 1026 is the minimum distance between each first limit slot and each second limit slot, that is, the distance between the rightmost first limit slot in the first limiter 1025 and the leftmost second limit slot in the second limiter 1026 is greater than or equal to the preset distance. In this way, the problem of the electromagnetic interference between the device under test and the comparison device affecting the test accuracy of the test device can be avoided.

[0156] It is worth noting that Figure 7 The first stopper 1025 and the second stopper 1026 shown are only provided for explaining the present embodiment, and do not mean that the first stopper 1025 and the second stopper 1026 in the present embodiment can only be used as Figure 7 The installation method shown in the figure does not mean that each first limit slot and each second limit slot can only be installed in Figure 7 It is sufficient to ensure that different positions and angles for placing the device under test and the comparison device can be provided, and the embodiments of the present application do not limit this.

[0157] It is worth noting that, since a plurality of limit slots with different tilt angles and different opening positions are respectively provided on the first limiter 1025 and the second limiter 1026, it is only necessary to place the device to be tested in different first limit slots and the comparison device in the corresponding second limit slots in different test wheels. In other words, it is not necessary to replace different position adjustment units 102 in different test wheels. In this way, the convenience of testing using the test device can be improved.

[0158] For one possible approach, see Figure 8 , the testing device also includes a fixing unit 104 .

[0159] The fixing unit 104 is connected to the driving unit 103 .

[0160] The fixing unit 104 is used to fix and support the driving unit 103 so as to balance the testing device.

[0161] Exemplarily, the fixing unit 104 may be connected to a portion of the driving unit 103 that is away from the turntable 101 , for example, the fixing unit 104 may be connected to the motor 1032 .

[0162] In this embodiment, the fixing unit 104 may include one or more brackets, and each bracket is fixedly connected to the driving unit 103 to ensure that the driving unit 103 and the testing device are balanced and not prone to tipping over.

[0163] On the basis of the above implementation mode and based on the same concept, the embodiment of the present application also provides a testing system, and its specific implementation process and technical effects are mentioned above and will not be repeated below.

[0164] The test system may include a comparison device and the test apparatus in any one of the above embodiments.

[0165] In this embodiment, the comparison device may be any device that has undergone a radio frequency performance test to ensure that the radio frequency performance is normal.

[0166] In addition, the comparison device may be of the same model or different model as the device to be tested, and may be adjusted according to actual needs, which is not limited in the embodiments of the present application.

[0167] In some possible implementations, the test system may also include any other possible components or devices, such as a power supply module, a speed monitoring module, etc. And any functions or effects that can be achieved in the above embodiments can be achieved through the components or devices in the test system. The embodiments of this application are not described in detail here.
