Trilithic Hunts Bursty Noise

Trilithic's 860DSPi TC-1 TraffiControl Option is used to see the ingress that is present "underneath" an upstream cable modem channel, or any bursty signal. Its display shows three traces: a Traffic trace, a Live Noise trace, and a Peak Noise trace. The Traffic trace shows the last captured signal containing traffic. The Live Noise trace shows the last captured signal without traffic. And the Peak Noise trace shows a persistent peak hold of the noise trace. The display lets a user see what is currently happening and captures peak interference levels of transient signals during the time that the measurement is being made.
