Command Syntax

:CHANnelN:WAVelength:VALue  <wavelength>

<wavelength> is a double.

Where N identifies a specific channel and must be selected from {1:8}{A|B|C|D}. For example, CHANnel3C.

Description

On optical channels,enters a calibrated wavelenth (in meters) for measurements. The channel will use the wavelength that is closest to the requested number. If the wavelength is not within 1% of a supported wavelength, an error will be generated.

  • To query a list of all available wavelengths, use the :CHANnel:WAVelength:VALue:VSET? query.
  • Although not the preferred method, you can select a calibrated wavelength by list order in the Reference Filter field of the channel Setup dialog, use the :CHANnel:WAVelength command.

The query form of the command returns the selected wavelength in meters. For example, 1310 nm would be returned as 1.31E-06.

Requires FlexDCA revision A.02.00 and above for query and A.05.30 and above for command.

The Wavelength selection is only displayed for plug-in modules with internal optical channels.

Prior to configuring the channel to use a user-defined wavelength, you must first perform an optical calibration on the wavelength.
