Abstract

A multilevel triggering system of a signal analysis instrument outputs a complex trigger signal. The triggering system includes a trigger controlled buffer for receiving and buffering an input signal, triggering function modules, and a triggering matrix. Each triggering function module performs a corresponding triggering function for detecting a corresponding triggering condition. The triggering matrix includes multiple triggering levels, each of which is configurable to include at least one trigger block and each trigger block being configurable to implement one of the triggering function modules. Each trigger block generates a corresponding block trigger when the triggering condition of the corresponding triggering function module is detected in the buffered input signal. Each triggering level generates a corresponding level trigger when the at least one trigger block in the triggering level generates the corresponding block trigger, and the triggering matrix generates the complex trigger signal when the triggering levels generate corresponding level triggers.
