3 Calibration Procedures
100 Keysight 34420A Service Guide
3 Connect a multifunction calibrator to the meter's input terminals using the
provided cable (Keysight PN 34102A). Ensure the connector coupling nut is
properly tightened.
4 Allow 5 minutes for the input connector to temperature stabilize.
5 Select each function and range in the order shown in Table 3-4. Apply the
input signal shown.
6 Turn on the menu and select G:CALIBRATE menu.
7 Move to the commands level and select 2:CALIBRATE.
8 Move down to the parameters level and set the value in the display to the
calibrator input value.
9 Execute the command to begin the gain calibration.
10 Repeat step 1 through step 9 for each function and gain listed in the table.
11 Perform the “Gain Verification Procedure” on page 84 to check the results.
