Turn Background Calibration Corrections Off
:CALibration:CORRections 0|1|OFF|ON
:CALibration:CORRections?
When set to OFF deactivates background flatness and IF gain
alignments, for which nominal values are substituted. Several video
shift gain corrections are set to zero, including absolute gain err, gain
err vs attenuation, and RF flatness err vs frequency. The IF gain DAC
is not compensated to adjust for prefilter gain but is set to a nominal
value. Typically used to facilitate troubleshooting.
