Auxiliary Voltage Measurement - Models N6781A, N6785A
Step 1. Connect the auxiliary input terminals to the output terminals of model
N6781A. Also connect the voltage input of the Keysight 3458A to the
output terminals of model N6781A (see Cal Setup E).
Step 2. Select the auxiliary voltage measurement input.
Front Panel:
From the Calibration menu, select
Voltage, Aux Measurement. Then
select Start.
Step 3. Select the first voltage calibration point.
Front Panel:
The first calibration point is automatically
selected. "Enter P1 measured data" should be

Step 4. Measure the output voltage with the DMM and enter the data. This value
may be positive or negative.
Front Panel:
Enter the value from the external DMM into
the data field and then select Next.
Step 5. Select the second voltage calibration point.
Front Panel:
The second calibration point is automatically
selected. "Enter P2 measured data" should be
displayed.
Step 6. Measure the output voltage with the DMM and enter the data.
Front Panel:
Enter the value from the external DMM into
the data field and then select Next.
Step 7. Select the third voltage calibration point for the negative range.
Front Panel:
The third calibration point is automatically
selected. "Enter P3 measured data" should be
displayed.
Step 8. Measure the output voltage with the DMM and enter the data. The value
should be negative.
Front Panel:
Enter the value from the external DMM into
the data field and then select Next. When
calibration is complete, select Close.
