Standard Calibration of AC Functions
Standard calibration of the AC Voltage and AC Current functions in the 9100 uses the
same procedure as that described in Sections 10.3.1 to 10.3.4 of this section except that
the frequency of the target calibration points must also be set.
10.3.5.1
Output Frequency Synthesis
The frequency of the Model 9100's AC Voltage and AC Current outputs is derived
digitally from an internal reference frequency crystal, which is sufficiently stable for the
output frequencies of these functions not to require any routine calibration throughout the
lifetime of the instrument. Option 100 introduces an alternative, high-stability reference
crystal.
10.3.5.2
Changing the Output Frequency of Target Calibration
Points.
When you display target selection screens for AC functions (by pressing the TARGET
screen key while in the Cal mode of the function screen), you will notice that the Saved
Calibration Targets and Default Calibration Targets all include a target calibration point
frequency. As an example, the default calibration targets for the AC Voltage 0.32001V
to 3.20000V, 0.0100kHz to 3.2000kHz hardware range are illustrated in the screen shown
below.
