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 (page 149). 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 “Creating a Sequence” on page 148.
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 Trigge r Type > Segment Advance > Continuous.
• Trigger source: Trigger hardkey
Press Trigger Source > Trigg er Ke y.
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 Tr igg er 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 Trigg er hardkey causes the first
segment in the waveform sequence to start when the last segment finishes.
