Configuring Resume Measurement
To configure Resume measurement, follow these steps:
1.
Select the High Speed measurement tab> More button> Resume
measurement. The device/HUB resumes the High-Speed operation, which is
indicated by the presence of High-speed SOF packets (with 400 mV
nominal amplitude) following the K state driven by the host controller. For
the Host, this is the time between the falling edge of D+ to the First SOF.
This should not exceed 3.0 ms.
2.
To access the Configure Measurements menu, go to Measurements>
Configure.
