Triggering a Waveform
Example: Segment Advance Triggering
Segment advance triggering enables you to control the segment playback within a waveform
sequence. This type of triggering ignores the repetition value (
). For example if a segment
has repetition value of 50 and you select
Single
as the segment advance triggering mode, the
segment still plays only once. The following example uses a waveform sequence that has two
segments.
If you have not created and stored a waveform sequence, refer to
.
1.
Preset the signal generator.
2.
Configure the RF output:
—
Set the desired frequency.
—
Set the desired amplitude.
—
Turn on the RF output.
3.
Select a waveform sequence for playback:
a.
Press
Mode
>
Dual ARB
>
Select Waveform
.
b.
In the
Sequence On
column, highlight a waveform sequence file.
c.
Press
Select Waveform
.
4.
Set the triggering as follows:
—
Trigger Type: continuous Segment Advance
Press
Trigger Type
>
Segment Advance
>
Continuous
.
—
Trigger source: Trigger hardkey
Press
Trigger Source
>
Trigger Key
.
5.
Generate the waveform sequence:
Press
ARB Off On
until On highlights.
6.
(Optional) Monitor the waveform:
Connect the RF OUTPUT of the signal generator to the input of an oscilloscope, and configure
the oscilloscope so that you can see the signal.
7.
Trigger the first waveform segment to begin playing continuously:
Press the
Trigger
hardkey.
8.
Trigger the second segment:
Press the
Trigger
hardkey.
Pressing the
Trigger
hardkey causes the currently playing segment to finish and the next
segment to start.
If the last segment in the sequence is playing, pressing the
Trigger
hardkey causes the
first
segment in the waveform sequence to start when the last segment finishes.
