In this case, COMINIT is sent from the signal generator and the host must respond with COMRESET or
COMWAKE.
QualiPHY prompts the user to look at the oscilloscope and see if the product is responding to the OOB signal. If
the product responds click Detect, otherwise, click No Detect.
OOB-02 – UI During OOB
This test measures the unit interval during the bursts of the COMRESET/COMINIT and COMWAKE signals.
Devices that implement Asynchronous Signal Recovery (ASR) automatically send out COMINIT signals when
powered on. For devices that do not support ASR, a signal generator is used to send a COMRESET to the device.
Hosts send out a COMRESET when powered on and may continue to send out COMRESET periodically if they
support ASR.
OOB-03 – COMINIT/COMRESET and COMWAKE Burst Length
This test measures the width of the COMINIT/COMRESET and COMWAKE bursts. It reports the mean of the 6
COMINIT/COMRESET burst widths and the mean of the COMWAKE burst widths as informational. Then, it
reports the mean, min and max of all 12 bursts.
OOB-04 – COMINIT/COMRESET Gap Length
This test measures the mean width of the 5 COMINIT/COMRESET gaps between the bursts.
OOB-05 – COMWAKE Gap Length
This test measures the mean width of the 5 COMWAKE gaps between the bursts.
