AC Voltage Gain and Flatness Calibration
This calibration procedure applies to all models (34460A/61A/65A/70A).

Flatness Calibration Considerations
before performing any calibration.
Configuration: AC Voltage
All AC calibration procedures use the 3 Hz bandwidth measurement filter.
1.
Configure each function and range in the order shown in the table below.
2.
Apply the input signal shown in the Input column.
3.
Enter the actual applied input voltage amplitude (see
). A Calibration Step
Succeeded message indicates success; if the display shows Calibration Step Failed, check the input
value, range, function, and entered calibration value and repeat the calibration step.
4.
Repeat steps 1 through 3 for each flatness calibration point shown in the table.
5.
Store the new calibration constants (see
Storing the Calibration Constants
).
Each voltage and frequency takes approximately 2.5 seconds to complete.
