Resistance Calibration - Models N6781A, N6785A
Step 1. Connect an electronic load directly to the output (see Cal Setup F). Set
the load to constant current mode, current to 0.95A. Also connect the
Keysight 3458A to the output terminals.
Step 2. Select the 20 V resistance range of output 1.
Front Panel:
SCPI Command:
From the Calibration menu, select Miscellaneous
Resistance, 20 V Range. Then select Start.
CAL:RES 20
(@1)
*OPC?
Step 3. Select the first resistance calibration point.
Front Panel:
SCPI Command:
The first calibration point is automatically
selected. “Enter P1 measured data” should be
displayed.
CAL:LEV P1
*OPC?
Step 4. Measure the output voltage with the DMM and enter the data.
Front Panel:
SCPI Command:
Enter the value from the external DMM into
the data field and then select Next.
CAL:DATA <data>
Step 5. Select the second resistance calibration point.
Front Panel:
SCPI Command:
The second calibration point is automatically
selected. “Enter P2 measured data” should be
displayed.
CAL:LEV P2
*OPC?
Step 6. Measure the output voltage with the DMM and enter the data.
Front Panel:
SCPI Command:
Enter the value from the external DMM into
the data field and then select Next.
CAL:DATA <data>
Step 7. Select the third resistance calibration point.
Front Panel:
SCPI Command:
The third calibration point is automatically
selected. “Enter P2 measured data” should be
displayed.
CAL:LEV P2
*OPC?
Step 8. Measure the output voltage with the DMM and enter the data.
Front Panel:
SCPI Command:
Enter the value from the external DMM into
the data field and then select Next. When
calibration is complete, select Close.
CAL:DATA <data>
Step 9. For Model N6781A repeat steps 1 through 8 for the 6 V resistance range
of output 1.
