[0056] This embodiment provides a testing method for passive devices, applied to the aforementioned computer terminal. Figure 2 This is a flowchart of a test method for a passive device according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:
[0057] Step S202: Obtain the target signal type of the target test signal to be sent by the passive intermodulation test device. The target test signal is used to perform passive intermodulation test on the passive device under test. The signal type of the test signal sent by the passive intermodulation test device is allowed to be divided into multiple signal types, including the target signal type.
[0058] Step S204: Adjust the operating mode of the test device connected to the signal transmission interface of the passive intermodulation test equipment to the target operating mode corresponding to the target signal type. The test device is connected to a test load, and the operating mode of the test device is divided into multiple operating modes, including the target operating mode. The multiple operating modes have a corresponding relationship with the multiple signal types.
[0059] Step S206: Control the testing device to transmit the target test signal in the target operating mode.
[0060] Through the above steps, the signal types of test signals that the passive intermodulation testing equipment can transmit are classified into multiple signal types. When passive intermodulation testing of the passive device under test is required, the target signal type of the target test signal to be transmitted by the passive intermodulation testing equipment can be obtained from these multiple signal types. The operating mode of the test device connected to the signal transmission interface of the passive intermodulation testing equipment is adjusted to the target operating mode corresponding to the target signal type. This achieves automatic adjustment of the operating mode of the test device according to the target signal type, avoiding the need to repeatedly plug and unplug standard components to transmit test signals of different signal types during passive intermodulation testing of the passive device under test. It also enables the control of the test device to transmit test signals of multiple signal types in multiple operating modes, greatly improving the efficiency of test signal transmission during passive intermodulation testing of passive devices. The above technical solution solves the problem of low efficiency in transmitting test signals during passive intermodulation testing of passive devices in related technologies, achieving a significant improvement in the efficiency of test signal transmission during passive intermodulation testing of passive devices.
[0061] In the technical solution provided in step S202 above, the signal types of the test signals that are allowed to be sent by the passive intermodulation test equipment can be divided into multiple signal types, but not limited to. When it is necessary to perform passive intermodulation test on the passive device under test, the target signal type of the target test signal can be obtained from multiple signal types, but not limited to, thereby realizing the classification of the test signal types sent by the passive intermodulation test equipment.
[0062] Optionally, in this embodiment, passive intermodulation can be, but is not limited to, in a nonlinear radio frequency circuit, where two or more signals of different frequencies act on a passive device with nonlinear characteristics, generating passive intermodulation products (PIM). Passive nonlinearity will cause a large number of intermodulation harmonic signals to be generated in the radio frequency signal. If the intermodulation products fall within the receiving band of the communication system, they will cause interference. Intermodulation interference can have a significant impact on mobile communication systems, especially in scenarios involving multiple systems combined or adjacent base stations. Figure 3 This is a schematic diagram illustrating an application scenario of a passive intermodulation testing device according to an embodiment of the present invention, such as... Figure 3 As shown, under the input signal (i.e., the target test signal mentioned above), the nonlinear device (i.e., the passive device under test mentioned above) may generate new frequency intermodulation harmonic signals, and these intermodulation harmonic signals may fall into the receiving band of the antenna (i.e., the passive device under test mentioned above). Some of the intermodulation harmonic signals will be transmitted by the antenna (i.e., the passive device under test mentioned above) along with the input signal, and some harmonic signals will form reflected signals, affecting normal mobile communication.
[0063] Optionally, in this embodiment, the passive device under test may be, but is not limited to, a passive intermodulation test device or other passive devices besides a passive intermodulation test device. The passive device under test may be, but is not limited to, passive devices including passive components such as resistors, capacitors, inductors, converters, inverters, resonators, filters, mixers and switches, such as antennas, loads, etc.
[0064] In one exemplary embodiment, the target signal type of the target test signal may be obtained, but is not limited to, by: obtaining a test request received by the passive intermodulation test device; if the test request is used to request calibration of the passive intermodulation test device during passive intermodulation testing, determining that the target signal type to which the target test signal generated by the passive intermodulation test device in response to the test request belongs is a calibration type; if the test request is used to request passive intermodulation testing, determining that the target signal type to which the target test signal generated by the passive intermodulation test device in response to the test request belongs is a test type.
[0065] Optionally, in this embodiment, when the test request is for calibrating a passive intermodulation test device, it can be determined that the target test signal belongs to the calibration type. In such cases, the effectiveness and accuracy of the passive intermodulation test device can be calibrated by measuring key indicators such as the passive intermodulation level of the passive intermodulation test device, thereby avoiding inaccurate measurement results of the passive device under test due to equipment problems of the passive intermodulation test device itself.
[0066] Optionally, in this embodiment, when the test request is used to perform passive intermodulation testing on the passive intermodulation test device, it is possible, but not limited to, to determine that the target test signal belongs to the test type. In such cases, intermodulation harmonic signals such as second-order, third-order, fifth-order, or seventh-order intermodulation products can be tested, thereby realizing the testing of the communication performance of the passive device under test.
[0067] In the technical solution provided in step S204 above, the operating mode of the test device may include, but is not limited to, multiple operating modes. It may indicate, but is not limited to, that a passive intermodulation test needs to be performed on the passive device under test when a target test signal is obtained. In such a case, the target signal type of the target test signal may be obtained, and then the operating mode of the test device may be adjusted to the target operating mode corresponding to the target signal type. This realizes the automatic switching of the operating mode of the test device according to the signal type of the test signal, avoiding the need to repeatedly plug and unplug the test device when the test device needs to transmit test signals of different signal types, and greatly improving the efficiency of the test device in transmitting test signals of different signal types.
[0068] Optionally, in this embodiment, the testing device can receive the target test signal sent by the passive intermodulation testing device through the signal transmission port, and automatically adjust the operating mode of the testing device to the operating mode corresponding to the target signal type according to the target signal type of the target test signal. Figure 4 This is a connection diagram of a passive intermodulation testing device and testing apparatus according to an embodiment of the present invention, as shown below. Figure 4 As shown, a test device is connected to the signal transmission interface of the passive intermodulation test equipment. The test device and the test load can be connected via, but are not limited to, a low intermodulation cable. The test device can be connected to the passive intermodulation test equipment continuously, without having to repeatedly plug and unplug the test device due to different signal types of the test signal. This greatly facilitates the test operation of the test personnel and improves the efficiency of testing the passive device under test.
[0069] It should be noted that, in Figure 4 The explanation only uses a rectangular signal transmission port, but the signal transmission port can be any shape suitable for actual testing, and the present invention does not limit it.
[0070] Optionally, in this embodiment, the correspondence between multiple operating modes and multiple signal types may include, but is not limited to, one operating mode corresponding to one signal type, or one operating mode corresponding to multiple signal types, or multiple operating modes corresponding to one operating mode, etc.
[0071] In one exemplary embodiment, adjusting the operating mode of the testing device to the target operating mode may include, but is not limited to, the following situations:
[0072] In scenario one, if the target signal type is calibration type, the operating mode of the test device is adjusted to calibration mode, wherein the test device operating in calibration mode operates as a standard component.
[0073] Optionally, in this embodiment, when the target signal type is calibration type, that is, when the passive intermodulation test equipment needs to be calibrated, the operating mode of the test device can be adjusted to calibration mode. The test device operating in calibration mode can be used as a standard to calibrate the passive intermodulation test equipment, thus ensuring the effectiveness and accuracy of the passive intermodulation test equipment.
[0074] Scenario 2: When the target signal type is a test type, the operating mode of the test device is adjusted to test mode, wherein the test device operating in test mode functions as an RF adapter.
[0075] Optionally, in this embodiment, when the target signal type is a test type, i.e., when passive intermodulation testing of the passive device under test is required, the operating mode of the test device can be adjusted to the test mode (which can be, but is not limited to, RF PASS (Radio Frequency PASS)). In this case, the test device can be, but is not limited to, the test signal output by the passive intermodulation test device and the passive intermodulation signal generated by the passive device under test are not affected in any way, just like an RF adapter.
[0076] Optionally, in this embodiment, the various signal types of the test signal may include, but are not limited to, calibration type, test type, etc., and the operating mode of the test device may be automatically adjusted to the target operating mode corresponding to the target signal type according to the target signal type of the target test signal.
[0077] In the technical solution provided in step S206 above, when it is necessary to perform passive intermodulation testing on the passive device under test, the target signal type of the target test signal can be obtained. In this case, the operating mode of the test device can be automatically adjusted to the target operating mode corresponding to the target signal type. This realizes automatic control of the test device to transmit the target test signal in the target operating mode, avoiding the need to repeatedly plug and unplug the test device to adjust the operating mode of the test device in order to enable the test device to transmit test signals of different signal types. This greatly saves the time required for the test device to transmit test signals of different signal types and improves the efficiency of the test device in transmitting test signals.
[0078] In one exemplary embodiment, the control test device transmitting the target test signal in the target operating mode may include, but is not limited to, the following situations:

The intermodulation data of the passive intermodulation test device in the frequency sweep range can be collected, and the intermodulation data can be compared with the standard data. If the error between the intermodulation data and the standard data is less than or equal to the error threshold, the passive intermodulation test device can be determined to be qualified; if the error between the intermodulation data and the standard data is greater than the error threshold, the passive intermodulation test device can be determined to be unqualified, and an alarm can be triggered.
[0081] Scenario 2: When the target operating mode is test mode, control the test device to forward the target test signal.
[0082] Optionally, in this embodiment, when the operating mode of the test device is adjusted to the test mode, the test device can be controlled to forward the target test signal. It can acquire the intermodulation signal data of the passive device under test responding to the target test signal, and compare the intermodulation signal data with the standard signal data. If the error between the intermodulation signal data and the standard signal data is less than or equal to the data error threshold, the passive device under test can be determined to be qualified.
