Frequency Accuracy Verification

Configuration: Frequency (CONFigure:FREQuency DEF, MIN)
1. Make sure you have read
2. Select the Frequency function, default range, 3 Hz filter, and 1 second aperture.
3. Connect the Keysight 33500B Series Function/Arbitrary Waveform Generator to the input terminals.
For the 34461A/65A/70A, use the front panel input terminals and select the front input terminals with
the Front/Rear switch.
4. Select each range in the order shown below. Provide the indicated input voltage and frequency. Com-
pare measurement results to the test limits shown below. (Be certain to allow for appropriate source
settling.)
