Abstract
A system includes a plurality of nodes. The plurality of nodes each communicate signals pursuant to a single channel plan. The channel plan includes predefined characteristics for each of a plurality of signal channels. The system further includes a spectrum analyzer, a switch, and a controller. The switch connects the spectrum analyzer to the nodes. The controller tests communication signals on at least one of the nodes by conducting a test plan. The test plan prescribes performance of at least an average power test. The controller also derives a total node power based on the average power test results.
