GRL USB Power Delivery & Data Loopback Volume Tester (GRL-V-UP)

All-in-One USB test solution for high port count reliability & fast production testing


  • Single setup tester for concurrent USB Power Delivery 3.0 negotiation, 1000W power loading, USB 2.0 and USB 3.2 data loopback testing
  • Test up to 10 ports concurrently in single 3U rack unit


GRL V-UP addresses the needs of test engineers with demanding test requirements for their USB Type-C/PD hosts, hub modules, docks, monitors, and chargers.

Modular and scalable, the V-UP can add up to 10 test cards in a single 3U rack unit chassis. Each test card supports loading of a single 100W USB-C port, or dual 60W USB-C ports. Users it can start with any number of test cards and add more cards based on increased testing volume. Additional 3U rack units can be fitted to the same rack to add even greater test capacity.

The GRL V-UP has an open API which allows test engineers to use their own software (C#, NI TestStand, Python, etc.) for control or take advantage of easy to use software developed by GRL.

Perfect for reliability and environmental chamber testing as well as high volume production testing requirements. Strong thermal airflow design allows for 1000W max to be continuously run per rack unit. USB test times can be designed to be less than a few seconds with a single setup.
