SENSe Subsystem Commands
[SENSe:]CHOP[:STATe] OFF|ON|0|1
[SENSe:]CHOP[:STATe]?
Turns the spectrum analyzer chop mode
ON
or
OFF
. Chop mode increases
dynamic range for long sweep times by subtracting ambient light.
[SENSe:]CORRection:RVELocity:MEDium AIR|VACuum
[SENse:]CORRection:RVELocity:MEDium?
Determines whether the wavelengths used and displayed are referenced to air
or vacuum.
[SENSe:]GORDer[:AUTO] OFF|ON|0|1
[SENSe:]GORDer[:AUTO]?
Specifies the spectrum analyzer grating order mode. When
ON
, allows the
instrument to select the best reflection order for the wavelength range. When
OFF
causes the instrument to use the first-order reflection, regardless of the
wavelength.
[SENSe:]POWer[:DC]:RANGe:AUTO OFF|ON|0|1
[SENSe:]POWer[:DC]:RANGe:AUTO?
Turns the automatic ranging feature
ON
or
OFF
. For improved dynamic range,
automatic ranging changes the input range during the sweep.
[SENSe:]POWer[:DC]:RANGe:LOCK OFF|ON|0|1
[SENSe:]POWer[:DC]:RANGe:LOCK?
Locks the transimpedance amplifier to the currently selected range.
[SENSe:]POWer[:DC]:RANGe:LOWer <numeric_value>[DBM|W|UW|NM|MW]
[SENSe:]POWer[:DC]:RANGe:LOWer?
Specifies the desired value for sensitivity. Default units are set by the
UNITs:POWer command.
Note
It is recommended this function be in
AUTO
mode.
