:CHANnelN: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.
