:CALibration:DISPlay:LEVel OFF|LOW|HIGH
:CALibration:DISPlay:LEVel?
Controls the amount of detail shown on the display while the alignment
routines are running. The routines run faster if they are off, so they do
not have to update the display.
Off - displays no trace points
Low - displays every 10th trace

Align the IF Flatness
:CALibration:FLATness:IF
:CALibration:FLATness:IF?
Finds the flatness shape of the current IF setup (prefilter, mgain,
natBW). This information is then used for compensating measurements
that use FFT functionality, like the spectrum measurement. The
alignment is done frequently in the background. This same alignment
is run as part of the CAL:ALL routine.
