FDwfAnalogInStatusAutoTriggered(HDWF hdwf, BOOL *pfAuto)

Parameters:

- hdwf – Interface handle.

- pfAuto – Returns TRUE if the acquisition was auto triggered.

The function above is used to verify if the acquisition is auto triggered.

FDwfAnalogInStatusData(

HDWF hdwf, int idxChannel, double *rgdVoltData, int cdData)

Parameters:

- hdwf – Interface handle.

- idxChannel – Channel index.

- rgdVoltData – Pointer to allocated buffer to copy the acquisition data.

- cdData – Number of samples to copy.

The function above is used to retrieve the acquired data samples from the specified idxChannel on the AnalogIn

instrument. It copies the data samples to the provided buffer.

FDwfAnalogInStatusNoise(

Parameters:

- hdwf – Interface handle.

- idxChannel – Channel index.

- rgdMin – Pointer to allocated buffer to copy the minimum noise data.

- rgdMax – Pointer to allocated buffer to copy the maximum noise data.

- cdData – Number of min/max samples to copy.

The function above is used to retrieve the acquired noise samples from the specified idxChannel on the AnalogIn

instrument. It copies the data samples to the provided buffer.

FDwfAnalogInStatusSample(HDWF hdwf, int idxChannel, double *pdVoltSample)

Parameters:

- hdwf – Interface handle.

- idxChannel – Channel index.

- pdVoltSample – Variable to receive the sample value.

The function above gets the last ADC conversion sample from the specified idxChannel on the AnalogIn

instrument.
