SENSe Subsystem Commands

[SENSe:]CHOP[:STATe] OFFON01

[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 AIRVACuum

[SENse:]CORRection:RVELocity:MEDium?

Determines whether the wavelengths used and displayed are referenced to air or vacuum.

[SENSe:]GORDer[:AUTO] OFFON01

[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 OFFON01

[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.

Note

It is recommended this function be in AUTO mode.

[SENSe:]POWer[:DC]:RANGe:LOCK OFFON01

[SENSe:]POWer[:DC]:RANGe:LOCK?

Locks the transimpedance amplifier to the currently selected range.

[SENSe:]POWer[:DC]:RANGe:LOWer <numeric_value>[DBMWUWNMMW]

[SENSe:]POWer[:DC]:RANGe:LOWer?

Specifies the desired value for sensitivity. Default units are set by the

UNITs:POWer command.
