304 Agilent X-Series Signal Generators SCPI Command Reference
Arb Commands
Dual ARB Subsystem–N5172B/82B ([:SOURce]:RADio:ARB)
With the multiple baseband generator synchronization feature active, this selection
is unavailable (see page 284 for more information).
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.
*RST FREE
:TRIGger:TYPE:GATE
Supported N5172B/82B
[:SOURce]:RADio:ARB:TRIGger:TYPE:GATE LOW|HIGH
[:SOURce]:RADio:ARB:TRIGger:TYPE:GATE?
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 inactive state occurs, the X- Series signal generator stops the waveform playback at the last
played sample point, then restarts the playback at the next sample point when the active state
occurs. For more information on triggering and to select gating as the trigger mode, see
“:TRIGger:TYPE” on page 302.
The following list describes the X- Series signal generator’s gating behavior for the polarity selections:
LOW The waveform playback stops when the trigger signal goes high and restarts when
the trigger signal goes low.
HIGH The waveform playback stops when the trigger signal goes low and restarts when
the trigger signal goes high.
*RST HIGH
:TRIGger:TYPE:SADVance[:TYPE]
Supported N5172B/82B
[:SOURce]:RADio:ARB:TRIGger:TYPE:SADVance[:TYPE] SINGle|CONTinuous
[:SOURce]:RADio:ARB:TRIGger:TYPE:SADVance[:TYPE]?
This commands selects the waveform’s response to a trigger signal while using the segment advance
(SADVance) trigger mode.
When the X- Series signal generator receives multiple trigger occurrences when only one is required,
the signal generator uses the first trigger and ignores the rest. For more information on triggering
and to select segment advance as the trigger mode, see “:TRIGger:TYPE” on page 302.
The following list describes the waveform’s response to each of the command choices:
