Keysight M9181A - Calibration Adjustment Process

Calibration
40 Keysight M9181A Calibration and Verification Procedure
Calibration of ACV “zeroes”
Because of the nature of the RMS conversion process, these points are NOT done
at 0 V but at the amplitude and frequency level indicated. Review “Test
Considerations” on page 16 and “Gain Adjustments” on page 36 before beginning
this procedure.
Configuration: AC Offset
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 33).
3 Perform the calibration process in the SFP: select the Step #, set the source,
enter the Calibrate Value, and click Store Calibration Constant.
NOTE
Before the ACV offset calibration step can be performed on a given range, the
ACV gain and flatness must be performed first. For example, you must perform
steps 12 and 17 before step 21.
