USB

Universal Serial Bus (USB) has grown to become a common interface in many embedded industrial, automotive, and consumer applications. What began with USB 2.0 operating at 480 Mb/s has grown to today’s USB 3.1, which transforms the USB interface into a high-speed (10Gb/s), high-power (up to 100 watts) platform. A new USB Type-C connector dramatically changes the user experience and paves the way for future, higher performance USB products.

USB 3.1 transmitter testing requires jitter and eye height measurements after applying an equalizer and clock recovery functions. USB 3.1 receiver testing checks for bit error ratio while injecting a worst case test pattern containing different forms of jitter. In addition, USB Type-C based designs may require power delivery (PD) testing as well as alternate modes such as DisplayPort or MHL serial buses.

Tektronix provides test tools to serve the validation, compliance, and debug needs of engineers designing USB 2.0, USB 3.1, USB PD and USB Type-C based systems, which are compliant to the USB-IF test standards.
