1 Calibration Procedures
48 Keysight U3606B Service Guide
3 Select each range in the order shown below. Provide the indicated input
frequency and current. Compare the measurement results to the appropriate
test limits in Table 1-10 (be certain to allow for appropriate source settling
when using the Fluke 5520A).
Diode voltage gain verification test
1 Connect the calibrator to the front panel (red) and LO (black) input
terminals (see Figure 1-9, “Test setup for diode voltage gain verification,” on
page 33).
2 Press [] to select the diode function. The diode annuciator will turn on
according to your selection.
3 Select the range shown below. Provide the indicated input voltage. Compare
the measurement results to the appropriate test limits in Table 1-11 (be certain
to allow for appropriate source settling when using the Fluke 5520A).
Output verification test
This test verifies that the output functions (constant voltage and constant current)
are within specifications. Note that the measurement values over the remote
interface should be identical to those displayed on the front panel.

You should consider programming the U3606B over the remote interface for this
test to avoid round off errors. See the U3606B Programmer’s Reference for more
information on remote interface programming.
