Triggering a Waveform
7. On the function generator, configure a TTL signal for the external gating trigger.
8. (Optional) Monitor the 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 active periods
(low in this example).
The following figure shows an example display.
