Instrument:Calibration:Cal ADC Input
- Updated2025-10-07
- 1 minute(s) read
Specifies the input of the calibration ADC. The ADC can take a reading from several inputs: the analog output, a 2.5 V reference, and ground. The latter two inputs are used to calibrate the ADC itself.
Note You cannot change this property while the device is generating a waveform. If you want to change the device configuration, call the
niFgen Abort Generation VI or wait for the generation to complete.
