For Standard combination USB-RX & USB-TX

For Standard combination USB-RX & USB-TX & DP-TX

The USB-TX tests with the Keysight Type-C fixture N7015A require the use

of transfer functions.

To get comparable USB RX-test results with the USB-IF fixture (left) and

the Keysight N7015A fixture (right), USB reference channel must be

embed the into the measurement signal and de-embed the N7018A

fixture.
