Q: Why Do We Need to Use the Regression Fixture with the GRL-USB-PD-C2 But Not with the GRL-USB-PD-C2-EPR?
A: Voltage regression on the GRL-USB-PD-C2 cannot be carried out beyond 3 V which is the reason why the regression fixture is required. On the other hand, voltage regression sequence can be run on the GRL-USB-PD-C2-EPR thus the regression fixture is not required.
