Triggering a Waveform
• Segment Advance mode plays a segment in a sequence only if triggered. The trigger source controls
segment–to–segment playing (see
received during the last segment loops play to the first segment in the sequence.
• Gated mode triggers the waveform at the first active triggering state, then repeatedly starts and
stops playing the waveform in response to an externally applied gating signal. See
Triggering on page 182.
