Combinatorial mask triggering in time or frequency domain

摘要

One or more mask triggers can be configured. Combinatorial mask triggering logic (170) can make various determinations about the relationship between a digitized signal and the one or more mask triggers. The various determinations about the relationship can include considerations of both space and time. When the combinatorial trigger criteria have been satisfied, a trigger signal (150) is generated, and the digital data associated with an incoming signal is stored to memory (115). The combinatorial mask triggering logic can operate on signals in the frequency domain, the time domain, or both.
