Calibrate and test USB4 receiver performance to USB-IF standards

Testing physical-layer (PHY) USB4 receivers for conformance or compliance requires a USB4 testbed comprised of a BERT, high-bandwidth oscilloscope, receiver test application software, and a USB4 microcontroller test module. The application software automates measurement and test case execution as specified in the USB4 Electrical Compliance Test Specification, as defined by the Universal Serial Bus Implementers Forum (USB-IF).

Precision testbed calibration is required to ensure the device under test passes conformance specification. This requires optimizing the transmitter equalizer and then finely calibrating the bit error ratio tester's (BERT) stress signal using a high-performance oscilloscope. During the receiver test, the BERT injects the stress signals on the lane under test. The test automation software and a USB4 microcontroller test module are used to perform the BER test, which validates whether or not the device under test exceeds the allowance defined by the USB compliance test specification.
