Internal ADC Adjustment/Self Calibration
The function generator stores calibration constants related to the gain
and offset of the internal ADC. Setup 6 must always be performed
before any later adjustments are attempted. The internal ADC is then
used as a source for the calibration constants generated in setup 7.
1 Make the connections as shown below.
2 Set the DMM to display 5 1/2 digits.
3 Enter the following setup, and then measure the dc value.
* Constants are stored after completing this setup.
4 Enter the measured value of the dc source using the numeric keypad or
knob.
Note This setup requires approximately 15 seconds to complete.
5 Disconnect all cables from the rear panel Modulation In connector.
