Chapter 4 Calibration Procedures

DC Output Adjustment

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.

1Use a DMM to measure the function generator dcV output voltage for each setup in the following table. These adjustments use a HIGH Z output termination.
