CALibrate:ROSCillator:MANual <frequency>
This command allows you to manually specify the calibrated frequency to be
used for the currently selected reference oscillator. The specified frequency value
is stored in non-volatile memory and overwrites the calibrated value stored
previously.
NOTE. To temporarily override the calibrated value without storing in non-vola-
tile memory, use the the SOUR:ROSC:VAL command.
