Triggering a Waveform
Trigger Type
Type defines the trigger mode: how the waveform plays when triggered.
NOTE The example below shows Dual ARB Mode, but trigger functionality is similar for other
modulation modes. Available trigger types vary depending on the modulation mode selected.
• Continuous mode repeats the waveform until you turn the signal off or select a different waveform,
trigger mode, or response (Free Run, Trigger & Run, Reset & Run).
• Single mode plays the waveform once.
NOTE In Single No Retrigger, do not use Continuous Reset & Run mode due to the variable latency of
this setup.
No Retrigger: If a trigger is received early it will be ignored. The gap in your playback is dependent
on the trigger period, after which time the RF will start up again where it is expected.
Buffered Trigger: An early trigger will cause the waveform to play to the end and then start again.
The RF will not be aligned with this early trigger.
Restart on Trigger: The ARB will reset itself and trigger again but there will some gap in the
playback while this is occurring. It will reset itself for every trigger it receives.

Trigger Type
Immediately triggers and plays the waveform; triggers
received while the waveform is playing are ignored.
Plays the waveform when a trigger is received;
subsequent triggers are ignored.
Plays the waveform when a trigger is received; subsequent
triggers restart the waveform.
The waveform stops during the inactive
state of the trigger source, and plays
during the active state.
Ignores an early trigger
received while a
waveform is playing.
An early trigger received
while a waveform is
playing waits until the
current waveform
completes, then plays
the waveform once
An early trigger received
while the waveform is
playing immediately
restarts the waveform.
A segment in a sequence plays
once, ignoring the repetition
setting, after which the dual ARB
player stops and waits for a
trigger before advancing to the
next segment. The next segment
then plays to completion.
If a trigger is received while a
segment is playing, the segment
plays to completion. The dual
ARB player then advances to the
next segment and plays that
segment to completion.
A segment in a sequence plays continuously until the waveform receives another trigger.
If a trigger is received while a segment is playing, the segment plays to completion. The
dual ARB player then advances to the next segment and plays that segment continuously.
