Injecting Additive White Gaussian Noise (Gaussian Noise) of varying power from Noisecom noise generators into the cable network is an effective way to assess the extent of cable network’s ability to cope with Gaussian Noise interferences of varying intensity. In this application note, we highlight area where Gaussian Noise should be added to examine its impact and uses some of the signal quality metrics to assess the health of the DOCSIS network.
