Run Test Sequences

The Sequencer function of the GRL-PSP is used to simulate several test cases in custom sequence for the UUT that is connected to USB Test Port 1 or Port 2 of the GRL-USB-PD-C2 / F1 Controller.

Here are the steps to configure and run test sequences:

  1. On the Sequencer screen, select the Port of the GRL-USB-PD-C2 / F1 Controller (that is connected with the UUT) and then select which Test to be performed. Click on the Add Test button to configure and add the test to the list on the left panel. Repeat this process if there are multiple tests to be added and run. The left panel should display a list of all selected tests for the respective Test Port of the GRL-USB-PD-C2 / F1 Controller
