Basic Digital Operation
Triggering Waveforms
Press
ARB Off On
to On.
8.
On the function generator, configure a TTL signal for the external gating
trigger.
9.
(Optional) Monitor the current waveform:
Configure the oscilloscope to display both the output of the signal
generator, and the external triggering signal. You will see the waveform
modulating the output during the gate
inactive
periods (low).
The following figure shows an example display.
NOTE
In the real–time Custom mode, the behavior is reversed: when the gating
signal is
high
, you see the modulated waveform.
Using Segment Advance Triggering
Segment advance triggering enables you to control the segment playback
within a waveform sequence. The following example uses a waveform
sequence that has two segments.
If you have not created and stored a waveform sequence, complete the steps in
the sections,
“Creating Waveform Segments” on page 104
Storing a Waveform Sequence” on page 105
1.
Preset the signal generator.
2.
Configure the RF output:
—
Set the desired frequency.
—
Set the desired amplitude.
—
Turn on the RF output.
