Basic Digital Operation (Option 653/655/656/657)
Triggering a Waveform
— Segment Advance mode plays a segment in a sequence only if triggered. The trigger source
controls segment–to–segment playing (see Example: Segment Advance Triggering on page
222). A trigger 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 Example:
Gated Triggering on page 223.
Trigger Source
External Trigger Polarity
— In Continuous, Single, and Segment Advance modes, use the Ext Polarity softkey to set the
external trigger polarity.
— In Gated mode, the Active Low and Active High softkeys ( page 220 ) determine the external
trigger polarity.
