Turn Background Calibration Corrections Off

:CALibration:CORRections 01OFFON

: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.
