Query Syntax

:CHANnel{1:8}{A|B|C|D}:FSELect:BANDwidth: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 reference filters in 3 dB bandwidth for the selected channel. For example,

"7.500000E+9, 998173E+9, 8.031919E+9, 8.031919E+9, 8.031919E+9…"

The reference filter values in the returned list are in the same order as they are listed in the Reference Filter field of the Channel Setup dialog (optical channels).

  • To select a reference filter based on 3 dB bandwidth, use the :CHANnel:FSELect:BANDwidth command.
  • Although not the preferred method, you can select a reference filter by list order in the Reference Filter field of the channel Setup dialog, use the :CHANnel:FSELect command.

Requires FlexDCA revision A.05.41 and above.
