Multi-Channel Triggering Apparatus and Method

Abstract:

An apparatus and a method for using a signal analyzer are disclosed. The apparatus includes an input port having a first plurality of input channels. The input port generates a digital data stream from each of the first plurality of input channels. The apparatus also includes a trigger bank having a second plurality of trigger processors, each trigger processor receiving a digital data stream chosen from the digital data streams and generating a trigger output having one of a plurality of possible values from the digital data stream. A trigger combiner that receives each of the trigger outputs and generates a trigger signal if the combined trigger outputs satisfy a predetermined criterion. A controller copies the digital data streams to a memory and copies the trigger processor outputs to the memory in response to the trigger combiner generating the trigger signal.
