• Set the desired amplitude.
• Turn on the RF output.
4. Select a waveform for playback (sequence or segment):
a. Preset the signal generator.
b. Press >
Mode Dual ARB
c. Highlight a waveform file (for this example, SINE_TEST_WFM).
d. Press
Select Waveform
5. Select the waveform trigger method:
a. Press >

ARB Off 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.
