Use the NI-FGEN ADC Control VIs only when following the calibration procedure of the signal generator.

niFgen Initialize Cal ADC Calibration VI
Initializes an external calibration session for ADC calibration. For the NI 5421/5422/5441, ADC calibration involves characterizing the gain and offset of the onboard ADC.
niFgen Write Binary 16 Analog Static Value VI
Writes a 16-bit value to the DAC, which could be output as a DC voltage.
niFgen Read CAL ADC VI
Takes one or more voltage measurements from the onboard calibration ADC and returns their average value. The signal that the ADC actually measures can be specified using the Cal ADC Input property. The ADC has some inherent gain and offset. These values can be determined during an external calibration session and stored in the calibration EEPROM.
niFgen Cal Adjust Cal ADC VI
Calculates calibration constants pertaining to the gain and offset of the onboard calibration ADC. During external calibration, you can generate voltages and measure them both externally and with the calibration ADC. The measured voltages are passed to this VI so that NI-FGEN can calculate the appropriate calibration constants and, when the calibration session is committed, store them in the onboard EEPROM.
