Query Syntax

:CHANnel{1:8}{A|B|C|D}:WAVelength:VALue:VSET?

Where the required specifier {1:8}{A|B|C|D} identifies a channel by its module slot number and channel letter. For example, channel 3C (CHANnel3C).

The channel specifier will fail if it does not include a slot number. If instead the suffix's channel letter is missing, the command defaults to letter A. As a result, the best practice is to always explicitly specify the channel by including both the module slot number and channel letter.

Description

Queries a list of available wavelengths in meters for the selected optical channel. For example,

"1.555E-6,850E-9,1.310E-6,1.550E-6,…"

The bandwidths in the returned list are in the same order as they are listed in the Wavelength field of the Channel Setup dialog (optical channels).

  • To select a calibrated wavelength by list order in the Reference Filter field of the channel Setup dialog, use the :CHANnel:WAVelength command.
  • To select a wavelength based on its value in meters, use the :CHANnel:WAVelength:VALue command.

Requires FlexDCA revision A.05.30 and above.
