Abstract:
1. A testing instrument for quantitatively determining a measurement of shielding integrity against signal ingress in a subscriber installation of a broadband communication system, said testing instrument comprising a tunable signal detector that can be tuned to a frequency of an over-the-air broadcast signal and measure signal power at said frequency of said over-the-air broadcast signal appearing in said subscriber installation, a global positioning system receiver, and a data processor that is programmed to provide a computation of a signal power level of said over-the-air broadcast signal at a location of said testing instrument determined by said global positioning system based on a location of a transmitter of known effective radiated power of said over-the-air broadcast signal for comparison with said signal power at said frequency of said over-the-air broadcast signal appearing in said subscriber installation as measured by said tunable signal detector as a said measurement of said shielding integrity of said subscriber installation against said signal ingress.
