Configuration
Commands
CONFigure:CenterWaveLength
Usage: CONF:CWL {centerWavelength}
Description: Sets the Center Wavelength (nm). The wavelength
parameter must be within the operating range of the
instrument.
Response:
None.
Notes: Setting the center wavelength will cause the start and end
wavelengths to be adjusted to match the new center
wavelength and the wavelength range set using the
CONF:RANG command.
If the center wavelength and Scan Range settings for a
measurement fall outside the most recent calibration, the
wavelength settings will be coerced to fit within the most
recent calibration.
CONFigure:CenterWaveLength?
Usage:
CONF:CWL?
Description: Retrieves the current Center Wavelength in nanometers.
Response: Returns the current Center Wavelength in nanometers.
