Low Range Voltage Measurement Calibration
This only applies to Agilent Models N6761A and N6762A.
Step 12. Select the low-voltage measurement range. This example selects the
5 volt measurement range of channel 1. The value to program a range
must be the maximum voltage of the range.
Front Panel:
Select
System\Admin\Cal\Function\Vmeas.
Step 13. Select the first voltage calibration point.
Front Panel:
Select Next. The information field
should indicate: Enter P1 data
Step 14. Measure the output voltage with the DVM and enter the data.
Front Panel:
Select the Measured Data field. Enter
the data from the external DVM.
Press Select when done.
Step 15. Select the second voltage calibration point.
Front Panel:
Select Next. The information field
should indicate: Enter P2 data
Step 16. Measure the output voltage with the DVM and enter the data.
Front Panel:
Select the Measured Data field. Enter
the data from the external DVM.
Press Select when done.
Press Next to finish calibration.
Voltage Common Mode Rejection Ratio Calibration
This only applies to Agilent Models N6751A, N6752A, N6761A and
N6762A.
Step 17. For this step only, refer to the following figure and connect a
jumper between the +sense and the −sense terminals. Connect a
second jumper from the +output to the −sense terminal. Connect a
25 ohm load resistor across the +output and –output terminals
(refer to the equipment list). This procedure is automatic and takes a
few seconds.
