Arcom Digital’s QAM Snare provides a method in which to detect and measure leakage from digital channels in an HFC network. In an all digital environment this means that it will no longer be necessary to allocate a 6MHz channel for leakage detection purposes. It is agile such that if forward ingress is affecting specific QAM channels, the location of the leak at the specific frequency can be quickly determined.

The QAM Snare can simultaneously detect both digital and analog leaks while utilizing a locating process significantly faster and more precise then current existing devices by using GPS and a technique called Hyperbolic location. Multiple leak detection points are used to determine the exact GPS coordinates of the leak source. This is much quicker, simpler, and more accurate than “triangulation”, “listen to a tone”, or “drive around recording” techniques.
