Command
[:SENSe]:POWer:IQ:RANGe:AUTO OFF | ON | 0 | 1
[:SENSe]:POWer:IQ:RANGe:AUTO?
Example Put the I Range and Q Range in manual
:POW:IQ:RANG:AUTO OFF
:POW:IQ:RANG:AUTO?
Notes :POW:IQ:RANG:AUTO is an alternate form of :VOLT:IQ:RANG:AUTO, to maintain consistency
with I Range and Q Range, which support both the POWer and VOLTage forms of the command
Preset
ON
Range Auto | Man
I Range
The internal gain range for the I channel when the Input Path is I Only or I and I/Q.
Used for both the I and Q channels when the Input Path is I+jQ.
Remote
Command
[:SENSe]:VOLTage:IQ[:I]:RANGe[:UPPer] <voltage>
[:SENSe]:VOLTage:IQ[:I]:RANGe[:UPPer]?
Example Set the I Range to 0.5 V Peak
:VOLT:IQ:RANG 0.5 V
:VOLT:IQ:RANG?
Notes The numeric entries are mapped to the smallest gain range whose break point is greater than or equal
to the value, or 1V Peak if the value is greater than 1V
Couplings When "Q Same as I" on page 1974 is On, the I Range value will be copied to "Q Range" on page 1973
Changing the value also sets Range = Man
Preset Complex SPECtrum Measurement: 0.5 V Peak
All others: 1 V Peak
State Saved Saved in instrument state
Range 1 V Peak (10 dBm @ 50 Ω) | 0.5 V Peak (4 dBm @ 50Ω) | 0.25 V Peak (-2 dBm @ 50Ω) | 0.125 V Peak (-
8 dBm @ 50Ω)
Min 0.125 V
Max 1 V
Annotation The Range annotation replaces the RF Input context's "Atten" annotation
"Rng: <I Range>". When Range = Man the annotation is preceded by "#"
The I Range is not annotated in Input Path Q Only. When I Range and Q Range are the same, the
annotation is "Rng: <Range>". When I Range and Q Range are different and the Input Path is Ind I/Q,
the annotation is "Rng: <I Range>, <Q Range>" and "Peak" is removed from the text. Examples:
"Rng: 1 V Peak" the I Range is 1 V Peak
"Rng: 1 V, 0.5 V " the I Range is 1 V Peak and the Q Range is 0.5V Peak
This is an alternate form of the command to allow entry as a power.
