Abstract

A combined analog and DSP trigger system for a digital storage oscilloscope (DSO) enables the DSO to real-time trigger on events in an input analog signal based on traditional trigger events in the input analog signal and/or predetermined anomalous events detected in digitized samples of the input analog signal. A processor receives the digitized samples at the input of an acquisition memory to detect the anomalous events and provides an event detect signal to the trigger system. Predetermined amounts of the digitized samples around the events are acquired in an acquisition memory for further processing and display.
