Frequency voltage gain verification test
1 Connect the calibrator to the front panel V (red) and LO (black) input terminals
(see Figure 1-7, “Test setup for frequency voltage gain verification,” on
page 32).
2 Press [Hz ms %] to select the frequency function.
3 Select each range in the order shown below. Provide the indicated input
frequency and voltage. Compare the measurement results and the appropriate
test limits in Table 1-9 (be certain to allow for appropriate source settling when
using the Fluke 5520A).
Frequency current gain verification test
1 Connect the calibrator to the front panel I (red) and LO (black) input terminals
(see Figure 1-8, “Test setup for frequency current gain verification,” on
page 32).
2 Press [Hz ms %] to select the frequency function.
