Abstract
A realtime power mask trigger generator for an instrument that acquires data in response to a trigger signal integrates power amplitudes over a defined bandwidth within a frequency spectrum for an input signal to produce an average signal power, and compares the average signal power with a specified reference power level for the defined bandwidth. Violation of the reference power level by the average signal power generates the trigger signal for acquiring data from the input signal about the trigger event by the instrument. The frequency spectrum may be divided into more than one defined frequency bandwidth, and each defined frequency bandwidth may have its own specified reference power level. The defined frequency bandwidths and associated reference power levels define a realtime power mask trigger.
