Frequency Accuracy Calibration - Keysight Truevolt Series Operating And Service Manual

Frequency Accuracy Calibration

This calibration procedure applies to all models (34460A/61A/65A/70A).
Review Test Considerations
Configuration: Frequency, 10 V range
The frequency accuracy of the Fluke 5720A is insufficient to calibrate the DMM. Its frequency output needs
to be calibrated against a more accurate reference. The Keysight 33500B Series Function/Arbitrary Wave-
form Generator is recommended for this calibration procedure.
1. Configure the instrument for frequency measurements at 10 V and 10 kHz, with 1 second gate time.
2. Apply a 10 kHz sine wave between 9 and 11 Vrms.
3. Enter the actual applied input frequency (see
ceeded 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. Store the new calibration constants (see
This calibration takes approximately 1 second to complete.
