And after receiving the test instruction, the network analyzer performs signal compensation on the test signal according to a preset calibration configuration file to obtain a compensation test signal, and then sends the compensation test signal to a product to be tested through a signal output port to test.

In this embodiment, the network analyzer performs signal compensation on the test signal through the preset calibration configuration file, so that signal loss caused by the radio frequency switch matrix device is reduced, and the test accuracy of the product to be tested is improved.

In one embodiment, as shown in fig. 9, a test flow chart of a product to be tested is enhanced; the product to be tested can be a high-speed direct-connection copper cable product comprising 16 pairs of differential signal transmission channels.

The test management terminal may communicate with the server through a network. The product to be tested is connected with the test board before testing, and the radio frequency switch matrix equipment is connected with the signal transmission channel in the product to be tested through the test board.

The test management terminal responds to a starting instruction, obtains the label information of the product to be tested input by a manager, the label information of the product to be tested is used for product tracing of the product to be tested, and then the test management terminal writes the obtained label of the product to be tested into a flash (flash memory) storage unit of the product to be tested through a test board. And then the test management terminal enters a test running state and carries out communication self-checking, when the network communication is normal, the configuration of the local database is updated, and test item information to be tested of the product to be tested is introduced from the local database. The test item information of the product to be tested is test information stored in advance, and comprises configuration information such as test requirements, specification files, channel calibration and the like. And if the network communication is abnormal, directly importing the test item information of the product to be tested, which needs to be tested, from the local database. And then the test management terminal starts testing, sends a test instruction and information to be tested corresponding to the test item information to the network analyzer according to the test item information, and sends radio frequency switch control information corresponding to the test item information to the radio frequency switch matrix equipment. And testing the product to be tested through the network analyzer and the radio frequency switch matrix equipment. And the test management terminal detects whether all signal transmission channels corresponding to the product to be tested are tested, and if the untested signal transmission channels exist, the test management terminal sends a switching test instruction to the network analyzer and the radio frequency switch matrix equipment to enable the network analyzer and the radio frequency switch matrix equipment to switch the signal transmission channels of the product to be tested and test the signal transmission channels. And the test management terminal acquires the signal analysis results corresponding to each signal transmission channel sent by the network analyzer and judges the test results, then the signal analysis results and the test results corresponding to the product to be tested are stored, and the test of the product to be tested is finished.
