Accurate and repeatable compliance testing requires access to the PHY transmitter output. The recommended approach is to use the Tektronix TF-XGbT Ethernet fixture. These fixtures can support all test setups while providing convenient test points for probing. If there is a provision to probe directly on DUT, user can perform compliance test without fixture.
