DC Output Adjustment
The function generator stores nine calibration constants related to DC volts
output. The constants are calculated from the adjustment value entered. The
calibration constants are stored following completion of SETUP 59. No
calibration constants are stored if the procedures are aborted at any other
setup.
1. Use a DMM to measure the function generator DCV output voltage
for SETUP 50 in the following table. These adjustments use a HIGH
Z output termination.
2. Send the CAL:VALue <measured Vdc> to the function generator.
3. Send the CAL? command to the function generator to initiate the
calibration.
4. Repeat steps 1, 2 and 3 for SETUP 51 through 59.
5. Perform the “DC Function Offset Verification” on page 168.
