5.19 :TRIGger Subsystem
Triggers control the playback by telling the BENCHTOP MICROWAVE SOURCEX000 when to play
the signal.
Depending on the trigger settings for the BENCHTOP MICROWAVE SOURCEX000, the waveform
playback can occur once, continuously, or the BENCHTOP MICROWAVE SOURCEX000 may start
and stop playing the waveform repeatedly (GATE mode). A trigger signal comprises both positive and
negative signal transitions (states), which are also called high and low periods. You can configure the
BENCHTOP MICROWAVE SOURCEX000 to trigger on either state of the trigger signal. It is common
to have multiple triggers, also referred to as trigger occurrences or events, occur when the signal
generator requires only a single trigger. In this situation, the BENCHTOP MICROWAVE
SOURCEX000 recognizes the first trigger and ignores the rest.
When you select a trigger mode, you may lose the signal from the RF output until you trigger the
waveform.
There are four parts to configuring the trigger:
Choosing the trigger type which controls the waveform’s transmission.
1) NORMal : trigger edge initiates/stops sweeps
2) GATE : trigger level starts/stops sweep
Setting the waveform’s response to triggers:
1. CONTinuous : repeatedly accepts trigger events
2. SINGle : uses only one trigger event
3. Selecting the trigger source which determines how the BENCHTOP MICROWAVE SOURCEX000
receives its trigger signal, internally or externally. The GATE choice requires an external trigger.
