Therefore, the high-speed signal testing unit judges whether the cable to be tested is subjected to high-speed link testing according to the result of the low-speed testing unit, the service life of the high-speed signal testing module is prolonged, and the cost is further reduced.

in BootLoader mode, the low-speed signal testing unit 1 waits to receive or receives a second software update packet for the low-speed signal testing unit 1 from the high-speed signal testing unit 2;
the high-speed signal testing unit 2 responds to the received first software updating data packet, and if the first software updating data packet is suitable for the low-speed signal testing unit 1, the first software updating data packet is forwarded to the low-speed signal testing unit 1 as the second software updating data packet; if the first software update data packet is suitable for the high-speed signal testing unit 2, recording the received first software update data packet to a local memory to update software for the high-speed signal testing unit 2, and sending a software update result thereof to the control and data storage unit 3;
the low-speed signal testing unit 3 records the received second software update data packet to a local memory to update software for the low-speed signal testing unit 1 in response to receiving the second software update data packet;
the low-speed signal testing unit 1 also sends the software updating result to the high-speed signal testing unit 2; the high-speed signal testing unit 2 sends the software updating result of the low-speed signal testing unit 1 to the control and data storage unit.
That is, in response to the software version information of the low-speed signal testing unit 1 not matching with the information of the test cable or the software version information of the control and data storage unit 3, the high-speed testing unit 2 receives the low-speed testing unit data packet transmitted by the control and data storage unit 3 and controls the low-speed testing unit 1 to perform software update.

Namely, the control updating unit forwards the software updating instruction and receives the updating content result of the related unit, and the result can embody the upgrading process and can be displayed in real time in a window form.
At this time, the control and data storage unit 3 stores the software identification to be updated locally in response to the software update instruction, and starts the control update unit, which obtains the flag of the unit to be updated and the type of update from the local when it is turned on.
The control and data storage unit 3 is further used for collecting active cable serial number information and production station information provided by a user, sending test commands to the high-speed signal test unit and the low-speed signal test unit according to the active cable serial number information and the production station information, controlling the flow and the content of the test, receiving, processing and storing data after the test is completed, and displaying test results to the user.
