SENSe Subsystem

The SENSe subsystem allows changes in how the instrument makes measurements and
provides information on the reference laser.

SENSe Subsystem Functions

:AVERage?

Description

Queries the number of readings being averaged for wavelength and power
values.

Query Response

{OFF | 2 | 4 | 8 | 16 | 32 | 64 | 128}

Examples

:SENS:AVER?

:AVERage {OFF | 2 | 4 | 8 | 16 | 32 | 64 | 128}

Description

Sets the number of readings being averaged for wavelength and power
values. It is the same as using the Average function through the display.

*RST value

OFF

Examples

:SENS:AVER OFF
:SENS:AVER 8

:MEDium?

Description

Queries the medium used for wavelength calculations.

Query Response

{AIR | VACUUM}

Examples

:SENS:MED?

:MEDium {AIR | VACuum}

Description

Sets the medium used for wavelength calculations. It is the same as using the
Medium function through the display.

*RST value

VAC

Examples

:SENS:MED AIR
:SENS:MED VAC

:POWeroffset?

Description

Queries the power offset being added to power values. It is the same as using
the Poffs function through the display. The power offsets are in units of
dBm.

Query Response

{OFF | 1 | 2 | 3 | ... | 19 | 20}

Examples
