[:SOURce]:IQ:SAMPle:STEP
Syntax [:SOURce]:IQ:SAMPle:STEP <value>
[:SOURce]:IQ:SAMPle:STEP?
Description Set the sample rate step of the IQ wavetable output.
Query the sample step rate of the IQ wavetable output.
Parameter Name Type Range Default
<value> Real 1Hz to 10MHz 1MHz
Explanation When <value> is set in "Number" form, the default unit is Hz; for example,
3000. In addition, < value> can also be set in "Number + Unit" form; for
example, 3kHz.
The default unit of the return value is Hz.
After the sample rate step of IQ wavetable output rotate theis set, you can
knob to modify the sample rate at the current step. At this point, you can query
or set the sample rate using the [:SOURce]:IQ:SAMPle command.
Return Format The query returns the sample step rate of the IQ wavetable output. For example,
3000.

[:SOURce]:IQ:TRIGger:ARB
Syntax [:SOURce]:IQ:TRIGger:ARB
Description Stop the waveform output manually.
Explanation When the operation mode after the IQ wavetable is triggered is set to "Arm Auto" or
"Arm Retrig", you need to use this command to stop the waveform output manually
and wait for the next trigger.

RETRig
Explanation RETRig: select the "Retrig" mode. At this point, the instrument outputs the
baseband s ignal continuously and restarts to output the signal each time a
trigger is received.
AMDAuto: select the "Arm Auto" mode. The instrument starts outputting the
waveform is continuously each time a trigger is received until "Arm ARB"
selected and then waits for the next trigger.
AMDRetrig: select the "Arm Retrig" mode. The instrument starts outputting the
waveform s continuously each time a trigger is received; the instrument restart
outputting the signal when another trigger is received until "Arm ARB" is
selected and then waits for the next trigger.
SINGle : select the "Single" mode. The instrument outputs the specified length
(specified in "Duration") of waveform each time a trigger is received and then
stops to wait for the next trigger.
Return Format The query returns the operation mode after the IQ modulation baseband signal is
triggered. For example, RETRIG.
Example :IQ:TRIG:OPTM RETR
:IQ:TRIG:OPTM?

Syntax [:SOURce]:IQ:TRIGger:SEGMent:CURRent?
Description Query the number of the current wavetable segment.
Return Format The query returns the number of the current wavetable segment. For example, 1.
[:SOURce]:IQ:TRIGger:SEGMent:EXECute
Syntax [:SOURce]:IQ:TRIGger:SEGMent:EXECute

Range
Default
<value> 0 Integer 0 to 63
Explanation The upper limit of <value> is determined by the total number of wavetable
segments of the "Segment" file currently loaded.
The number of the next segment of the wavetable increases by 1 automatically
each time a next segment trigger is executed by sending the
[:SOURce]:IQ:TRIGger:SEGMent:EXECute command.
The command is valid only when the "Segment" file is loaded.
Return Format The query returns the number of the next segment of the wavetable. For example, 2.
