The embodiment of the present application does not impose any special restrictions on the specific type of the electronic device 100.
[0038] The electronic device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) connector 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera module 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, an air pressure sensor 180C, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a proximity light sensor 180G, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.
[0039] The processor 110 may be a system on chip (SOC), which may include multiple subsystems. The subsystems of the SOC may include but are not limited to a central processing unit (CPU) subsystem, a graphics processing unit (GPU) subsystem, and a neural processing unit (NPU) subsystem.
[0040] It is to be understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.
[0041] The wireless communication function of the electronic device 100 can be implemented through the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor and the baseband processor.
[0042] The mobile communication module 150 can provide solutions for wireless communications including 2G / 3G / 4G / 5G, etc., applied to the electronic device 100. The mobile communication module 150 may include at least one filter, a switch, a power amplifier, a low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves from the antenna 1, and filter, amplify, and process the received electromagnetic waves, and transmit them to the modulation and demodulation processor for demodulation.

[0043] The modem processor may include a modulator and a demodulator. Among them, the modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 194. In some embodiments, the modem processor may be an independent device.

[0045] The method provided in the embodiment of the present application can be applied to the scenario of performing communication performance coupling test on the mobile communication module and the wireless communication module of the electronic device. The communication performance coupling test is intended to simulate the working state of the electronic device in different wireless environments, so as to measure the strength, stability and coverage of its wireless signal. The communication performance coupling test can help determine whether the device can provide a reliable connection under various network conditions.
[0046] The communication performance coupling test can include the transmission performance test and the receiving performance test. The transmission performance test mainly detects the signal transmission capability of the device under test under different conditions. By measuring indicators such as transmission power, frequency stability, bandwidth utilization, harmonics and spurious emissions, it is determined whether the device under test can provide a strong and stable signal in actual use. The receiving performance test mainly detects the ability of the device under test to receive external wireless signals. These indicators can show whether the device can stably receive signals in a weak signal environment or when there is an interference source.
[0047] Through the transmission and reception performance tests, it can be ensured that the device under test can provide stable and efficient communication under various network conditions, improve the user experience in actual use, and reduce problems such as easy disconnection and high latency.
[0048] The embodiment of the present application provides a test device, which may include multiple probes, a test box and an analysis device. The multiple probes may be arranged at different positions of the test box, and the probes may be connected to the analysis device via a radio frequency line. The analysis device is used to transmit radio frequency signals and may also measure and detect the signal transmission performance of the electronic device.
[0049] The probe can convert RF signals into electromagnetic waves and transmit them into space, or receive electromagnetic waves in space and convert them back into RF signals. Specifically, when the test instrument generates RF signals, the probe acts as a transmitting antenna to convert these RF signals into corresponding electromagnetic waves and spread them into the space of the test environment. Conversely, when there are electromagnetic waves in space, the probe acts as a receiving antenna to capture these electromagnetic waves and convert them back into RF signals, which are then transmitted to the test instrument for further analysis and processing. This ensures that the signal is transmitted to the device under test at the specified power and frequency.
[0050] The test box has two functions. On the one hand, the test box provides a shielding function, separating the space inside and outside the test box, thereby effectively isolating the external electromagnetic signal interference. This shielding effect ensures the purity of the test environment and makes the test data more accurate and reliable. By shielding external interference signals, the test box can simulate ideal test conditions and avoid the influence of external electromagnetic interference on the test results, thereby improving the accuracy and repeatability of the test. On the other hand, the test box also has a fixing function, which can firmly fix the probe and the device under test, ensuring that the relative position of the probe and the device under test remains stable during the test process, avoiding test errors caused by movement or vibration. The fixing function also keeps the conditions consistent between multiple tests, improving the repeatability of the test and the reliability of the data.
[0051] When the receiving performance test is performed on the device under test, the analyzing device transmits a wireless radio frequency signal, and then the device under test detects the signal receiving capability of each device under test according to the signal strength of the received wireless radio frequency signal.
[0052] For example, the devices to be tested are 4 mobile phones, and the 4 mobile phones are placed in the respective slots of the test box. In response to the start signal of the reception performance test, the frequency, modulation mode, bandwidth, target power and other parameters of the signal are set, and a wireless radio frequency signal is generated using a signal analysis device. The wireless radio frequency signal is converted into an electromagnetic wave through a probe and transmitted into space, so that the 4 mobile phones can receive the signal at the same time. The receiving module of the mobile phone receives the signal sent by the probe and performs corresponding signal processing on the received signal. The signal strength received by each mobile phone is measured, and the received signal strength indication value is recorded. The corresponding reception performance test result is determined according to the received signal strength indication value of each mobile phone, and the reception performance of each mobile phone is detected according to the reception performance test result to determine whether it meets the test requirements.
[0053] When the transmission performance test is performed on the device under test, the device under test transmits a test signal, and then the analysis device determines the signal transmission capability of each device under test based on the test signals transmitted by the multiple devices under test.
[0054] For example, the devices to be tested are 4 mobile phones, the mobile phones may be numbered AD, the number of probes is 15, the probes may be numbered 1-15, probes numbered 1-9 are deployed on the front of the test box, and probes numbered 10-15 are deployed on the side.
[0055] In response to the test start signal, in the first test cycle, mobile phone A continuously transmits the preset channel power signal, and the analysis device is connected to probe 1, and receives the preset channel power signal sent by mobile phone A. Then the probe is switched by the RF switch, and the analysis device is connected to probe 2, and receives the preset channel power signal sent by mobile phone A, ..., and then the probe is switched by the RF switch, and the analysis device is connected to probe 15, and receives the preset channel power signal sent by mobile phone A. After completing the signal reception of all probes, the analysis device processes and calculates the final result, determines the signal transmission capability of mobile phone A, and defines that the result comes from mobile phone A.
[0056] In the second test cycle, mobile phone B continuously transmits the preset channel power signal, and the analysis device is connected to probe 1, and receives the preset channel power signal sent by mobile phone B. Then the probe is switched by the RF switch, and the analysis device is connected to probe 2, and receives the preset channel power signal sent by mobile phone B, ..., and then the probe is switched by the RF switch, and the analysis device is connected to probe 15, and receives the preset channel power signal sent by mobile phone B. After completing the signal reception of all probes, the analysis device processes and calculates the final result, determines the signal transmission capability of mobile phone B, and defines that the result comes from mobile phone B.
[0057] In the third test cycle, mobile phone C continuously transmits the preset channel power signal, and the analysis device is connected to probe 1, and receives the preset channel power signal sent by mobile phone C. Then the probe is switched by the RF switch, and the analysis device is connected to probe 2, and receives the preset channel power signal sent by mobile phone C, ..., and then the probe is switched by the RF switch, and the analysis device is connected to probe 15, and receives the preset channel power signal sent by mobile phone C. After completing the signal reception of all probes, the analysis device processes and calculates the final result, determines the signal transmission capability of mobile phone C, and defines that the result comes from mobile phone C.
[0058] In the fourth test cycle, mobile phone 4 continuously transmits the preset channel power signal, the analysis device is connected to probe 1, and receives the preset channel power signal sent by mobile phone D. Then the probe is switched by the RF switch, the analysis device is connected to probe 2, and receives the preset channel power signal sent by mobile phone D. Then the probe is switched by the RF switch, ..., the analysis device is connected to probe 15, and receives the preset channel power signal sent by mobile phone D. The second test cycle is later than the first test cycle, the third test cycle is later than the second test cycle, and the fourth test cycle is later than the third test cycle.
[0059] After completing the signal reception of all probes, the analysis device processes and calculates the final result, determines the signal transmission capability of mobile phone D, and defines that the result comes from mobile phone D.
[0060] However, in the above scheme, only one mobile phone can send out a signal of the target frequency at the same time, and the analysis device is responsible for receiving and processing the signal. During each test, one mobile phone completes the signal transmission test before starting the same test on the next mobile phone. This method is a serial test. Therefore, the entire test process is time-consuming and inefficient. In addition, during the test of each mobile phone, the probe connected to the analysis device needs to be switched multiple times. Each mobile phone needs to switch the probe 15 times, which not only increases the complexity of the operation, but also causes the signal interaction device to wait for a long time during each switching process, further extending the total test time.
[0061] Based on the improvement of the above scheme, this application adjusts the transmission performance test of each device under test to parallel testing. Through parallel testing, multiple devices under test can transmit radio frequency signals at the same time, which not only speeds up the data acquisition speed but also reduces the errors caused by repeated operations. In addition, the parallel testing method also optimizes the utilization rate of test resources, so that the performance test of more devices can be completed in the same time, which greatly reduces the time required for the test process and improves the test efficiency.
[0062] See also Figure 2, an embodiment of the present application provides a testing method, which is applied to a testing device, the testing device includes a plurality of probes and an analysis device, and each probe has a different relative position to the device under test, such as Figure 2 As shown, the test method includes:
[0063] S201: receiving test signals simultaneously transmitted by a plurality of devices under test within a preset signal receiving period.
[0064] After starting the transmission performance test of the device under test, the probe can receive the test signals transmitted by multiple devices under test at the same time within the preset receiving period, and the frequency of the test signal transmitted by each device under test can be different. By setting a corresponding and unique transmission frequency for each device under test, the detection process of the transmission capability of each device under test can be independent and will not interfere with each other, so that the transmission performance test of multiple devices can be completed quickly.
[0065] For example, the frequency of the test signal corresponding to the device under test A may be a, the frequency of the test signal corresponding to the device under test B may be b, the frequency of the test signal corresponding to the device under test C may be c, and the frequency of the test signal corresponding to the device under test D may be d.
[0066] When the probe receives the test signal emitted by the device under test, it needs to receive the test signals emitted by all the devices under test within a certain period of time. In one possible implementation, receiving the test signals emitted simultaneously by each device under test within a preset signal receiving period includes: receiving test signals of different frequencies in different sub-time periods according to the correspondence between the frequency of the test signal and the sub-time period.
[0067] During the preset receiving period, all devices under test will transmit signals at the same time, and the test device will receive these signals synchronously. This method can ensure that the signals of all devices under test are successfully captured and recorded in the same time period, thereby improving test efficiency and data consistency. The test device can obtain the transmission data of all devices in the same time window, providing comprehensive and reliable data support for subsequent analysis and comparison. The preset signal receiving period can include multiple sub-time periods, and each sub-time period receives test signals of different frequencies.
[0068] For example, the preset signal receiving cycle may include four sub-time periods, and the test device can receive a test signal with a frequency of a in the first sub-time period, the test device can receive a test signal with a frequency of b in the second sub-time period, the test device can receive a test signal with a frequency of c in the third sub-time period, and the test device can receive a test signal with a frequency of d in the fourth sub-time period.
[0069] In different signal receiving cycles, the test signal receiving task can be completed by probes arranged at different positions, and the probes connected to the analysis device can be switched through the radio frequency switching switch. In a feasible implementation, the method further includes: sending a radio frequency switching signal, and switching the test signals received by different probes in response to the radio frequency switching signal.
[0070] After the current signal receiving cycle ends, the analysis device may send a radio frequency switching signal to the radio frequency switching switch, and after receiving the radio frequency switching signal, the radio frequency switching switch switches the probe currently connected to the analysis device.
[0071] For example, in the first signal receiving cycle, the test signal receiving task can be completed by the probe numbered 1. In response to the RF switching signal, the probe connected to the analysis device is switched from the probe numbered 1 to the probe numbered 2, and in the second signal receiving cycle, the test signal receiving task can be completed by the probe numbered 2,… In response to the RF switching signal, the probe connected to the analysis device is switched from the probe numbered N-1 to the probe numbered N, and in the Nth signal receiving cycle, the test signal receiving task can be completed by the probe numbered N.
[0072] S202: Determine the signal transmission capability of each device under test according to the received test signals transmitted by the multiple devices under test.
[0073] After receiving the test signals transmitted by all the devices under test, the analysis device needs to use this as a basis to analyze the test signals transmitted by each device under test one by one, so as to determine whether the device under test can transmit a stable signal within the specified power range.
[0074] The signal transmission capability of each device under test can be determined by determining the signal strength of the test signal transmitted by each device under test. In a possible implementation, the signal transmission capability of each device under test is determined based on the test signals transmitted by the multiple devices under test, including: determining the signal transmission capability of each device under test based on the signal strength of the test signal.
[0075] After receiving the test signal processed and forwarded by the probe, the analysis device performs corresponding signal processing and analysis operations to determine the signal strength of the test signal emitted by each device under test. Then, the signal transmission capability of each device under test can be determined based on the matching relationship between the signal strength of the test signal emitted by each device under test and the preset calibration value.
[0076] For example, there are four devices under test, namely A, B, C and D. During the test, each device transmits a test signal, which is processed and forwarded to the analysis device through the probe. After receiving the signal, the analysis device performs signal processing and analysis operations to determine the signal strength of each device. Then, these signal strengths are matched with the preset calibration interval to determine the signal transmission capability of each device. The preset calibration interval can be set as: the interval is -45 dBm to -50 dBm, indicating excellent signal transmission capability, the interval is -51 dBm to -55 dBm, indicating medium signal transmission capability, and the interval is -56 dBm to -60 dBm, indicating weak signal transmission capability.
[0077] After analysis and processing, the analysis equipment determines that the signal strength measurement value of the test signal transmitted by the device A under test is -52 dBm, the signal strength measurement value of the test signal transmitted by the device B under test is -49 dBm, the signal strength measurement value of the test signal transmitted by the device C under test is -57 dBm, and the signal strength of the test signal transmitted by the device D under test is -53 dBm.
[0078] The signal strength of the device A under test is -52 dBm, which falls within the calibration range of -51 dBm to -55 dBm, and has medium transmission capability; the signal strength of the device B under test is -49 dBm, which falls within the calibration range of -45 dBm to -50 dBm, and has excellent transmission capability; the signal strength of the device C under test is -57 dBm, which falls within the calibration range of -56 dBm to -60 dBm, and has weak transmission capability; the signal strength of the device D under test is -53 dBm, which falls within the calibration range of -51 dBm to -55 dBm, and has medium transmission capability.
[0079] The signal transmission capability is a comprehensive performance indicator of the strength and quality of wireless signals transmitted at different frequency bands and power levels. In a possible implementation, the signal transmission capability includes WIFI signal transmission capability and cellular signal transmission capability.
[0080] WIFI signal transmission capability refers to the strength and quality of wireless signals transmitted by a device in a wireless LAN environment. It involves the ability of a device to transmit signals in the 2.4GHz and 5GHz frequency bands, including aspects such as signal strength, coverage, spectrum purity, modulation accuracy, and anti-interference capability. Specifically, WIFI signal transmission capability includes the power level of the signal transmitted by the device, signal stability, signal clarity, and the performance of the device in the face of multipath propagation and other wireless interference. Good WIFI signal transmission capability can ensure that the device provides stable and fast wireless network connections in a wider area, supports multiple devices to access the network at the same time, and maintains efficient data transmission in various usage scenarios.
[0081] Cellular signal transmission capability refers to the comprehensive performance of the strength and quality of wireless signals transmitted by a device in a cellular network environment. It includes the ability of the device to transmit signals in different frequency bands, covering signal strength, spectrum purity, modulation accuracy, and stability under various network conditions and environmental interference. Devices with high cellular signal transmission capabilities can maintain good signal coverage over a larger range, ensuring the speed and reliability of data transmission, and providing stable communication services whether in city centers, suburbs or on the move.
[0082] The following will be combined with the attached Figure 3 The operation diagram shown in the figure provides an overall description of the scheme of this application. Figure 3 , the devices to be tested are 4 mobile phones, the mobile phones can be numbered AD, the number of probes is 15, the WIFI signal transmission capability of the devices to be tested is described, the probes can be numbered 1-15, the probes numbered 1-9 are deployed on the front of the test box, and the probes numbered 10-15 are deployed on the side.
[0083] In the first signal transmission cycle, mobile phone A transmits the power signal of WIFI 1 channel, mobile phone B transmits the power signal of WIFI 3 channel, mobile phone C transmits the power signal of WIFI 5 channel, and mobile phone D transmits the power signal of WIFI 7 channel. The analysis device is connected to probe 1 through the RF switch, and receives the frequency signals of WIFI 1 channel, WIFI 3 channel, WIFI 5 channel, and WIFI 7 channel in sequence in each sub-time period of the signal reception cycle.
[0084] In the second signal transmission cycle, mobile phone A transmits the power signal of WIFI 1 channel, mobile phone B transmits the power signal of WIFI 3 channel, mobile phone C transmits the power signal of WIFI 5 channel, and mobile phone D transmits the power signal of WIFI 7 channel. The analysis device is connected to probe 2 through the RF switch, and receives the frequency signals of WIFI 1 channel, WIFI 3 channel, WIFI 5 channel, and WIFI 7 channel in sequence in each sub-time period of the signal reception cycle.
[0085] ..., in the fifteenth signal transmission cycle, mobile phone A transmits the power signal of WIFI 1 channel, mobile phone B transmits the power signal of WIFI 3 channel, mobile phone C transmits the power signal of WIFI 5 channel, and mobile phone D transmits the power signal of WIFI 7 channel. The analysis device is connected to the probe 15 through the RF switch, and receives the frequency signals of WIFI 1 channel, WIFI 3 channel, WIFI 5 channel, and WIFI 7 channel in sequence in each sub-time period of the signal receiving cycle.
[0086] It can be seen that in the test method provided by the present application, all devices under test can transmit signals at the same time, realizing parallel testing of the emission performance detection of the devices under test. For example, if there are 4 devices under test and 15 probes, in the non-parallel test scheme for the emission performance detection of the devices under test, the test processes of the 4 devices under test are the same and independent and there is a time sequence, while in the scheme of the present application, the test processes of the 4 devices under test are the same and independent but performed at the same time, thus speeding up the data acquisition speed and greatly reducing the time required for the test process. And the number of probe switching is matched with the number of probes. For example, if there are 4 devices under test and 15 probes, in the non-parallel test scheme for the emission performance detection of the devices under test, the probes need to be switched 60 times, while in the scheme of the present application, only 15 probes need to be switched, thus greatly reducing the time required for probe switching, further reducing the time required for testing. If the detection device can demodulate signals of different frequencies at the same time, the time required for testing will be further reduced. For example, if the detection device can demodulate the frequency signals of WIFI 1 channel, WIFI 3 channel, WIFI 5 channel, and WIFI 7 channel at the same time, the test time required for the detection device will be further reduced.
[0087] See also Figure 4 The embodiment of the present application provides a testing method, which is applied to a testing system. The testing system includes the aforementioned testing device and a plurality of devices to be tested. The method includes:
[0088] S401: In response to a test start signal, a plurality of devices under test transmit test signals simultaneously.
[0089] After receiving the test start signal, the device under test will first parse the signal to determine the specific type of the current test. The parsing process may include decoding the identification information in the test signal, identifying the test parameters and configuration requirements. Through parsing, the specific type of test can be confirmed, such as a WIFI signal transmission capability test, a cellular signal transmission capability test, or other types of wireless performance tests. Once the test type is determined, the device under test will generate and transmit the corresponding test signal according to the requirements of the test type. These test signals may include wireless signals of different frequency bands and different power levels, or signals modulated according to specific modulation methods and spectrum characteristics.
[0090] S402: receiving test signals simultaneously transmitted by a plurality of devices under test within a preset signal receiving period.
[0091] After multiple devices under test transmit test signals simultaneously, the probe can receive the test signals transmitted simultaneously by multiple devices under test within a preset receiving period, and the frequency of the test signal transmitted by each device under test can be different. By setting a corresponding and unique transmission frequency for each device under test, the detection process of the transmission capability of each device under test can be independent and will not interfere with each other, so that the transmission performance test of multiple devices can be completed quickly.
[0092] S403: Determine the signal transmission capability of each device under test according to the received test signals transmitted by the multiple devices under test.
