Triggering Waveforms

3.Configure the carrier signal output:

Set the desired frequency.

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 > Select Waveform.

c.Highlight a waveform file (for this example, SINE_TEST_WFM).

d.Press Select Waveform.

5.Select the waveform trigger method:

a.Press Trigger > Gated.

b.Press Trigger > Trigger Setup and note that for the Gate Active Low High softkey, the default selection is High, which is the selection used in this example.

6.Select the trigger source and rear panel input:

a.For the Trigger Source softkey, the default selection is Ext, which is the selection used in this example (gated triggering requires an external trigger).

b.Press Trigger Source and note that for the Ext Source softkey, the default selection is Patt Trig In 1, which is the selection used in this example.

7.Generate the waveform: 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.
