Agilent X-Series Signal Generators SCPI Command Reference 403
Real–Time Commands
Custom Subsystem–Option 431([:SOURce]:RADio:CUSTom)
This commands selects the waveform’s response to a trigger signal while using the continuous trigger
mode.
For more information on triggering and to select the continuous trigger mode, see “:TRIGger:TYPE”
on page 402.
The following list describes the waveform’s response to each of the command choices:
FREE
Turning the ARB format on immediately triggers the waveform. The waveform repeats
until you turn the format off, select another trigger, or choose another waveform file.
TRIGger The waveform waits for a trigger before play begins. When the waveform receives the
trigger, it plays continuously until you turn the format off, select another trigger, or
choose another waveform file.
RESet The waveform waits for a trigger before play begins. When the waveform receives the
trigger, it plays continuously. Subsequent triggers reset the waveform to the beginning.
For a waveform sequence, this means to the beginning of the first segment in the
sequence.

:TRIGger:TYPE:GATE:ACTive
Supported N5172B/82B with Option 431
[:SOURce]:RADio:CUSTom:TRIGger:TYPE:GATE:ACTive LOW|HIGH
[:SOURce]:RADio:CUSTom:TRIGger:TYPE:GATE:ACTive?
This command selects the active state (gate polarity) of the gate while using the gating trigger mode.
The LOW and HIGH selections correspond to the low and high states of an external trigger signal.
For example, when you select HIGH, the active state occurs during the high of the trigger signal.
When the active state occurs, the signal generator stops the waveform playback at the last played
sample point, then restarts the playback at the next sample point when the inactive state occurs. For
more information on triggering and to select gating as the trigger mode, see “:TRIGger:TYPE” on
page 402.
The following list describes the gating behavior for the polarity selections:
LOW
The waveform playback stops when the trigger signal goes low (active state) and
restarts when the trigger signal goes high (inactive state).
HIGH The waveform playback stops when the trigger signal goes high (active state) and
restarts when the trigger signal goes low (inactive state).
