Basic Digital Operation (Option 651/652/654)Triggering a WaveformExample: Gated TriggeringGated triggering enables you to define the on and off states of a modulating waveform.1. Connect the output of a function generator to the signal generator’s rear panel PAT TRIG INconnector, as shown in the following figure. This connection is applicable to all external triggeringmethods. The optional oscilloscope connection enables you to see the effect that the trigger signalhas on the RF output.2. Preset the signal generator.3. Configure the RF output:• Set the desired frequency.• Set the desired amplitude.• Turn on the RF output.4. Select a waveform for playback (sequence or segment):a. Press Mode > Dual ARB > Select Waveform.b. In the Segment On or Sequence On column, highlight a waveform.c. Press Select Waveform.5. Set the triggering as follows:• Trigger type: GatedPress Trigger Type > Gated.• Active state: LowPress Active Low.• Trigger source: ExternalPress Trigger Source > Ext.• Input connector: Rear panel Patt Trig In BNCPress Ext Source > Patt Trig In 1.6. Generate the waveform: Press Return > ARB Off On until On highlights.176 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
