s3, responding to the optical fiber rate information sent by the computer to configure the configurable crystal oscillator, so that the optical fiber rate of the ZYNQ core controller is consistent with that of the tested digital TR component, and the LED is lightened to indicate the state that the optical fiber rate is consistent;
and S4, responding to the setting parameters sent by the computer, performing test communication with the tested digital TR component through the four-channel SFP optical fiber transceiver, and simultaneously storing and reading test data in the DDR3 chipset.
6. The test method according to claim 5, wherein the setting parameters include a synchronization period, a recording data file size, and a recording data file path when the test apparatus is configured in a data recording function mode, and S4 includes:
the optical fiber transceiver module receives echo data sent by the tested digital TR component and sends the echo data to the data routing and command analysis module;
the data routing and command analysis module adds a period segmentation packet header before echo data of each synchronization period according to the synchronization period, stores the packet header and the echo data into the DDR3 chip set through the DDR3 control module, stops writing into the DDR3 chip set when the received data amount is equal to the size of a recorded data file, reads out data stored in the DDR3 chip set through the DDR3 control module, and sends the data to the computer through the PCI bus interface module;
the computer stores the received data into the data-recording data file path.
