A pattern recognition system to qualify valid triggering for digital storage oscilloscopes. Valid trigger qualification may be established from recognition of triggering level and interval time information, as well as other pattern-related information, to start or stop waveform acquisition. Trigger qualification may be established from either a pattern match or a mismatch. The trigger recognition system may be further extended to the occurrence of complex signals, such as those associated with television, rotating machinery, or other phenomena occuring in predetermined or known patterns.
