ACV Spot Frequency Calibration

The ACV Spot frequency mode calibration is not normally performed as part of routine
calibration. ACV Spot frequency calibration is only performed if the user intends to make
use of spot frequency mode. In spot frequency mode the accuracy of AC Voltage
measurements can be improved by calibrating the 8508A at specific frequencies of
interest, reducing frequency response flatness errors at these points. The following
procedure provides guidance on spot frequency calibration for users wishing to make use
of Spot frequency mode.
