:CHANnel:ATTenuator:DECibels
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.
