• For a measurement of 50.50 Ω, CF = 0.5 ( 50 / 50.50 + 1) = 0.9951.

• For a measurement of 49.62 Ω, CF = 0.5 ( 50 / 49.62 + 1) = 1.0038.

3. Connect the arbitrary function generator output to the DMM as shown in the following figure. Be sure to connect the 50 Ω terminator to the arbitrary function generator AFG Output connector.

5. Measure the voltage readout on the DMM.

6. Multiply the DMM voltage by the calculated CF to get the corrected offset voltage. Enter the resulting value in the Measurement field in

the following table.

Function Offset Measurement Range

DC + 1.25 Vdc Vdc 1.23025 Vdc to 1.26975 Vdc

DC 0.000 Vdc Vdc - 0.001 Vdc to + 0.001 Vdc

DC - 1.25 Vdc Vdc -1.26975 Vdc to -1.23025 Vdc

7. Change the AFG output amplitude to the next value in the table, measure the voltage readout on the DMM, multiply the DMM readout by the calculated CF to get the corrected offset voltage, and enter the resulting value in the Measurement field in the table.

8. Verify that the corrected offset measurements are within the range.
