3. Set-up the equipment with these conditions:
Frequency meter: Gate time = one second
DPI 620-IS:
4. Use the calibration menu
calibration then do the calibration checks
5. To make sure the frequency calibration is correct, set-up the
equipment to do one of these calibration checks:
•
Frequency (measure) calibration check
Signal generator: Output = 10 V, unipolar,
DPI 620-IS:
•
Frequency (source) calibration check
Frequency meter: Gate time = one second
DPI 620-IS:
6. Measure or source the specified values
Table 10-9): Hz then kHz. Make sure the error is in the
specified limits.
Table 10-8: Hz error limits (measure/source)

Amplitude = 10 V;
Frequency = 990 Hz
