Keysight M9182A/M9183A Calibration and Verification Procedure 53
AC Current Gain and Offset Calibration Procedure
Review “Test Considerations” on page 16 and “Gain Adjustments” on page 44
before beginning this procedure.
1 Configure each function and range shown in the table below.
2 Apply the input signal shown in the “Input” column of the table. Enter the
actual applied rms input voltage (see “Adjustments” on page 41).
Enter the actual applied input amplitude in Amps rms (see “Adjustments” on
page 41).
3 Perform the calibration process in the SFP: select the Step #, set the source,
enter the Calibrate Value, and click Store Calibration Constant.
Repeat steps 1 through 3 for each gain adjustment point shown in the above
table. Store the new calibration constants (see “Storing the Calibration
Constants” on page 41).
NOTE
Before the ACI Offset on a given range can be performed, the ACI gain on that
range must be performed (for example, you must perform step 35 before step
39).
