QAM INGRESS Mode provides a spectrum view of ingress noise,
CSO/CTB, and other coherent noise occurring at levels beneath the digital
signal. It allows a view “under the signal” by removing the QAM signal and
displaying the remaining spectrum. By isolating specific noise impairments
at particular channels and frequencies, this mode displays the size and
location of ingress in relation to the digital carrier without taking the carrier
out of service.
