Query Syntax

:CHANnel{1:8}{A|B|C|D}:FSELect:RATe: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 symbols-per-second (Bd) for the selected channel. For example,

"155.000E+6,622.000E+6,1.250000E+9,2.488000E+9,…"

The reference filter values (b/2) 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 its position in the dialog list, use the :CHANnel:FSELect command.
  • To select a reference filter bandwidth based on rate (Bd), use the :CHANnel:FSELect:RATe command.

Requires FlexDCA revision A.05.30 and above.
