Hello Bulat

Kindly refer below information from equipment,it says that DUT should be configured to transmit slave signal.

but i don;t quite understand the meanings of transmit slave signal.There is no link partner in this test,then how to make 1100 to transmit slave signal.

It would be better to ask the tool vendor, which 100BASE-T1 test mode is to be used. Since it says about Slave Mode, try to use Test Mode 3.

I think you need to consult with requirements/recommendations of your test equipment.
