:CHANnel:SIRC
Command Syntax
:CHANnel{1:8}{A|B|C|D}:SIRC {ON | OFF | 1 | 0}
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}:SIRC?
Query Response
{1 | 0}
Description
Turns on or off the application of channel SIRC (System Impulse Response Capability) data for N1092, N1060A, N1046A, 86105C, 86105D, 86115D, or 86116C modules with Option IRC. The correction data compensates for the optical module's specific response. This ensures that eye diagrams appear identical between different modules.
Requires an N1092, N1060A, N1046A, 86105C, 86105D, 86115D, or 86116C module with Option IRC.
Pattern lock must be turned on (:TRIGger:PLOCk) before you can apply SIRC data.
