USB A High Speed Signal Quality Test Fixture Set


Product Summary

The original model name used by USB-IF: USB2SIGQUAL

This fixture set contains two types of test fixtures:

  1. USB-A HS Device SQ Fixture (Model Name: AUT20132)
  2. USB-A HS Host SQ Fixture (Model Name: AUT20038)

In 2020, Allion took the test fixtures USB-TF-HS-Host-V21 and USB-TF-HS-Host-V20 and redesigned them into the new fixtures AUT20132 and AUT20038. In the new fixtures, the SMA connectors can be easily switched if necessary, and the overall test quality will be improved.

Allion also redesigned the AUT20132 jumper design into a switch, while changing the self-power connector into a USB Type-C port.
