Dual Arbitrary Waveform Generator
Using Waveform Triggers
Using Waveform Triggers
The dual arbitrary waveform generator includes several different triggering options: single, gated, segment
advance, and continuous. The trigger source can be the
Trigger hardkey, a command sent through the remote
interface, or an external signal applied to the TRIGGER IN rear panel connector.
To Use Segment Advance Triggering
Using this procedure, you learn how to control sequence playback of two waveform segments using segment
advance triggering.
If you have not created and stored a waveform sequence, complete the steps in the previous sections,
“Creating Waveform Segments” on page 100, and “Building and Storing a Waveform Sequence” on
page 101.
Configuring the Waveform Sequence Trigger
1. Press
Preset.
2. Press
Mode > Dual ARB > Select Waveform.
3. Highlight a waveform sequence file (for example, TTONE100+MTONE200).
4. Press
Select Waveform.
5. Press
Trigger > Segment Advance.
6. Press
Trigger > Trigger Setup > Trigger Source > Trigger Key.
7. Press
Return > Return > ARB Off On to On.
The first waveform segment in the sequence (TTONE) plays and modulates the RF carrier. The waveform
player has been programmed to stop the playback of the current waveform segment and start the playback of
the next waveform segment in the sequence when a trigger is received from the front panel
Trigger hardkey.
You can now enable the RF output and use the signal.
Triggering the Second Waveform
1. Press the
Trigger hardkey.
2. Observe the second waveform segment in the sequence (MTONE) is now playing.
Pressing the
Trigger hardkey stops the playback of the first waveform segment and starts the playback of the
second waveform segment. Pressing the
Trigger hardkey again will return the waveform player to the first
waveform segment.
