Basic Digital Operation
Triggering Waveforms
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. Highlight a waveform sequence file.
c. Press
Select Waveform.
4. Select the waveform trigger method and trigger source:
a. Press
Trigger > Segment Advance.
b. Press
Trigger > Trigger Setup and note that the Seg Advance Mode softkey displays the default selection
(Continuous), which is the selection used in this example.
c. Press
Trigger Source > Trigge r K e y .
5. Generate the waveform sequence:
Press
Return > Return > ARB Off On to On.
6. Trigger the first waveform segment to begin playing repeatedly:
Press the
Trigge r hardkey.
7. (Optional) Monitor the current waveform:
Connect the output of the signal generator to the input of an oscilloscope, and configure the oscilloscope
so that you can see the output of the signal generator.
8. Trigger the second segment:
Press the
Trigge r hardkey.
The second segment in the sequence now plays. Pressing the
Trigger hardkey causes the current playback
to finish and the next segment to start; when the last segment plays, pressing the
Trigger hardkey causes
the first segment in the waveform sequence to start when the current segment finishes.
Using External Triggering
Using this procedure, you learn how to utilize an external function generator to apply a delayed
single-trigger to a custom multicarrier CDMA waveform.
