Figure 18. Example of a Device Detecting 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-07
– COMINIT/COMRESET Gap Detection
This test measures the response of the product to COMINIT/COMRESET with different gap widths. A signal
generator is used to send COMRESET to a device or COMINIT to a host. A device should respond to
COMRESET by sending COMINIT. A host should respond to COMINIT by sending COMWAKE or COMRESET.
The setup is the same as OOB-06. The setup and expected responses on the oscilloscope are the same as for
OOB-01.
When using the PeRT

the result is tested by the PeRT

and not by the oscilloscope.
When not using the PeRT

QualiPHY will prompt 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.
