Resistance Calibration
Step 1. Connect an electronic load directly to the N6781A output (see Cal
Setup F). Set the load to constant current mode, current to 0.95A.
Also connect the Agilent 3458A to the N6781A output terminals.
Step 2. Select the 20 V resistance range of output 1.
Front Panel:
SCPI Command:
Select System\Admin\Cal\Misc\Resistance.
Then select the High range.
CAL:RES 20 (@1)
*OPC?
Step 3. Select the first resistance calibration point.
Front Panel:
SCPI Command:
Select Next. The information field should indicate:
“Enter P1 measured data”
CAL:LEV P1
*OPC?
Step 4. Measure the output voltage with the DMM and enter the data.
Front Panel: SCPI Command:
Select the Measured Data field. Enter the data
from the external DMM. Press Select when done.
CAL:DATA <data>
Step 5. Select the second resistance calibration point.
Front Panel: SCPI Command:
Select Next. The information field should indicate:
“Enter P2 measured data”
CAL:LEV P2
*OPC?
Step 6. Measure the output voltage with the DMM and enter the data.
Front Panel: SCPI Command:
Select the Measured Data field. Enter the data
from the external DMM. Press Select when done.
CAL:DATA <data>
Step 7. Select the third resistance calibration point.
Front Panel:
SCPI Command:
Select Next. The information field should indicate:
“Enter P1 measured data”
CAL:LEV P2
*OPC?
Step 8. Measure the output voltage with the DMM and enter the data.
Front Panel: SCPI Command:
Select the Measured Data field. Enter the data
from the external DMM. Press Select when done.
Press Next to finish calibration.
CAL:DATA <data>
Step 9. Repeat steps 1 through 8 for the 6 V resistance range. This time,
select the Low range.
