Q: If the user observes the BUSIDLE test case result as a Fail and the description says to verify signal capture, does this testify as a true failure from the UUT?

A: Basically in the BUSIDLE test, the DUT/UUT sends the Goodcrc command along with noise. At times, the GRL-USB-PD-C2 tester may not be able to decode the Goodcrc command. Thus the user is recommended to load the HSADC trace and check whether or not Goodcrc is present after noise. The test result can be considered as a PASS if Goodcrc is present.
