A method and an apparatus for performing link equalization testing via a physical layer test and measurement system. The system includes a protocol aware test apparatus for transmitting testing data, a device under test for receiving the transmitted testing data, and an oscilloscope for receiving an output waveform from the device under test. The protocol aware test apparatus selects a first of a plurality of preset values, sends an equalization signal from the protocol aware test apparatus to the device under test, and changes a speed of communication to a predetermined speed and sends a compliance pattern to the device under test after placing the device under test in a loopback mode. A waveform output from the device under test is captured by the oscilloscope, and is analyzed to determine compliance of the device under test with a predetermined link equalization speed in accordance with a predetermined protocol.
