3 Calibration
68 Series N6700 Service Guide
Step 7. Select the third voltage calibration point for the negative range.
Front Panel: SCPI Command:
Select Next. The information field should
indicate: “Enter P3 measured data”
CAL:LEV P3
*OPC?
Step 8. Calculate the shunt current (I=V/R) and enter the data. The value
should be negative.
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.

Low Range Current Programming
Step 1. Connect only the current measurement terminals of the Agilent
3458A to the output terminals (see Cal Setup D without the resistor).
Step 2. Select the low-current programming range. The value to program a
range must be the maximum current of the range. Models N6781A
and N6782A have 300 mA range. Model N6784A has a 100 mA and a
10 mA range. This example selects the 300 mA programming range of
output 1. For model N6784A, select the 100 mA programming range.
Front Panel: SCPI Command:
Select System\Admin\Cal\Curr\Iprog
Then select the Low1 range.
CAL:CURR 0.3, (@1)
Step 3. Select the first current 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 current with the Agilent 3458A and enter the value. This
value may be positive or negative.
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 current calibration point.
Front Panel: SCPI Command:
Select Next. The information field should indicate:
“Enter P2 measured data”
CAL:LEV P2
*OPC?
