[0125] Optionally, generating a test result according to the feedback signal and / or the test signal includes:

[0126] When the test type of the dual-mode communication unit to be tested is a first radio frequency receiving performance test, generating a second test result for testing the first radio frequency receiving performance of the dual-mode communication unit to be tested according to the first radio frequency signal;

[0127] When the test type of the dual-mode communication unit to be tested is a second radio frequency receiving performance test, generating a third test result for testing the second radio frequency receiving performance of the dual-mode communication unit to be tested according to the second radio frequency signal;

[0128] When the test type of the dual-mode communication unit to be tested is an adjacent channel interference performance test, generating a first test result of testing the radio frequency transmission performance of the dual-mode communication unit to be tested according to the first radio frequency signal and the third feedback signal;

[0129] When the test type of the dual-mode communication unit to be tested is an EVM performance test, generating a fourth test result for testing the EVM performance of the dual-mode communication unit to be tested according to the signal to be tested;

[0130] When the test type of the dual-mode communication unit to be tested is a protocol consistency test, a fifth test result for testing the protocol consistency performance of the dual-mode communication unit to be tested is generated according to the first feedback signal and the second feedback signal.

[0131] In one embodiment, the test type is an adjacent channel interference performance test. The signal instruction unit is an industrial computer, the first signal unit and the second signal unit are both radio frequency sources, and the first processing unit is a spectrum analyzer. The specific test steps are as follows:

[0132] Step 1: Determine the test type as adjacent channel interference performance test.

[0133] Step 2, the industrial computer controls the RF source 1 to generate a waveform signal, one of which is sent to the spectrum analyzer for storage, and the other is continuously sent to the dual-mode communication unit sample to be tested through the signal distribution unit and the RF channel unit. At the same time, the RF source 2 is controlled to generate a waveform signal of a channel adjacent to the first waveform signal, and is also continuously sent to the dual-mode communication unit sample to be tested. The signal passes through the dual-mode communication unit sample to be tested and is then sent to the spectrum analyzer. The spectrum analyzer compares the two received signals. If they are consistent, the number of successful communications is recorded as +1;

[0134] Step 3: Count the success rate. If the success rate is less than 90%, end the test. If the success rate is greater than 90%, continue to increase the signal strength sent by the interference channel until the reception success rate is just less than 90%. End the current test and record the signal gain of the interference compared to the current channel.

[0135] Step 4: The test is finished.

[0136] In one embodiment, the test type is an EVM performance test. The signal instruction unit is an industrial computer, and the second processing unit is an EVM evaluation board, which is designed using FPGA. The specific test steps are as follows:

[0137] The dual-mode communication unit sample to be tested sends a wireless signal, which is sent to the EVM S evaluation board through the RF channel unit. The EVM evaluation board determines whether the received signal meets the spectrum mask requirements. The test is completed.

[0138] In one embodiment, the test type is a protocol consistency test. The signal instruction unit is an industrial computer, and the specific test steps are as follows:

[0139] The industrial computer controls the auxiliary signal unit to send out a standard data frame, the carrier signal is sent to the dual-mode communication unit sample to be tested through the carrier channel unit, and the wireless signal is sent to the dual-mode communication unit sample to be tested through the radio frequency channel unit. After receiving the data frame, the dual-mode communication unit sample to be tested performs the specified action and feeds back the action result (response frame) to the auxiliary signal unit through the carrier channel unit and the radio frequency channel unit. The auxiliary signal unit determines whether the response frame meets the requirements. The test is over.
