All Universal Serial Bus (USB) products require USB-IF-authorized compliance testing for USB4 certification to ensure seamless interoperability. Follow the USB Type-C Thunderbolt Alternate Mode Electrical Host / Device Compliance Test Specification to ensure that you transmit your signal correctly. Testing a USB4 transmitter requires a high-performance real-time oscilloscope to capture and analyze transmitted patterns.
For USB4 transmitter test, an oscilloscope with a sampling rate of 50 GSa/s or greater on two channels simultaneously and 50 M samples of memory per channel is needed. New measurements for jitter, phase, and slew rate complicate testing, with short and long-channel test cases demanding additional setups. Compliance test software automates the test process and provides reports of test results, including analysis to show the pass or fail margins for each test.
