USB receiver jitter tolerance margin test with single-click operation.

Debugging DUT loopback issues are difficult because typical BERTs don't support protocol handshaking and logging. The protocol sequencer in the Tektronix BSX series BERT solution addresses the challenge of debugging loopback issues.

Receivers can be expensive to design and overdesigning margins on the receiver can be even more expensive. It’s a tricky affair to ensure that the receiver has sufficient margin to pass compliance, be competitive, while maintaining the cost of the parts. Margin analysis tools on the BERTScope help you understand the margin available on early designs and make the right kind of trade off decisions before you finalize your designs.

When the DUT is in loopback, all states and sub-states colors will be ‘green’. If not the failed states turn ‘red’ and are clickable to receive a diagnostic message.
