Abstract
A measurement instrument is provided with an FFT module providing a frequency domain output; and a power calculator connected to the frequency domain output to measure power statistics for a test signal of arbitrary length. In some embodiments, a spectrum integration module is provided to calculate the power contained within a frequency band. In an embodiment, a filter/averaging module is provided to compute signal power statistics over an arbitrary time period. Accumulators may be provided to store data related to maximum power, minimum power, average power, or peak to average power. A CCDF module may be provided in some embodiments to calculate CCDF related measurements. Also provided are methods of making power statistic measurements.
