Command Syntax

:CHANnel{1:8}{A|B|C|D}:ATTenuator:DECibels <attenuation>

Where <attenuation> is a double.

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.

Query Syntax

:CHANnel{1:8}{A|B|C|D}:ATTenuator:DECibels?

Description

Enters or queries an attenuation compensation factor in decibels. Use the :CHANnel:ATTenuator:RATio command to enter a factor based on ratio. Use the :CHANnel:ATTenuator:STATe command to turn attenuation compensation on and off. To reset the attenuation factor to 0  (1:1), use the :CHANnel:ATTenuator:RESet command. For more information on attenuation factors, refer to the :CHANnel:ATTenuator:STATe command.

Enter attenuation as a positive value. Gain is implied when you enter negative decibel values.

Requires FlexDCA revision A.01.80 and above.
