3.
Set-up the equipment with these conditions:
4.
Use the calibration menu (
Section 10.3
) to do a one-point
calibration then do the calibration checks (
step 5
).
Calibration check
5.
To make sure the frequency calibration is correct, set-up the
equipment to do one of these calibration checks:
•
Frequency (measure) calibration check (
Section 3.2.8
):
•
Frequency (source) calibration check (
Section 3.2.8
):
6.
Measure or source the specified values (
Table 10-8
or
Table 10-9
): Hz then kHz. Make sure the error is in the
specified limits.
