Query Syntax

:CALibrate:CHANnel{1:8}{A|B|C|D}:NOISe?

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

Returns the channel’s RMS noise for the current bandwidth, filter, and wavelength selection. The noise was measured during the most recent channel calibration or dark calibration.

Bandwidth (:CHANnel subsystem's :CHANnel:BANDwidth command)
Wavelength (:CHANnel subsystem's :CHANnel:WAVelength command)
Filter (:CHANnel subsystem's :CHANnel:FILTer command)

Requires FlexDCA revision A.06.80 and above.

Example Command
