The view ingress test measures any unwanted signals from outside the cable
TV system which can cause degradation of the receiver's quality.
The view ingress test places a reference marker at the peak carrier level
and activates the delta marker so that you can position it on the unwanted
signal. The LISTEN AT MKR function allows you to listen to the signal to
help determine the source.
Note that this test is only available in Channel mode.
