PCi-4472 24-bits of resolution and Labview6.1

[remifab]

I try to read 24 bits data from the PCI-4472 with Labview and after record the data into a binary file. Although the DAQ have a resolution of 24-bits I can't find Vi to read those 24-bits (it seems that Data Acquisition VIs acquire only 16-bits data). So anyone know if there is a solution to keep the 24-bits resolution?

The AI Read DAQ function in LabVIEW can return data in a scaled format or a binary format. At this point, the binary data is only returned as I16, so you would be losing bits. The scaled data is returned in an SGL format (32 bits), which will give you all of the resolution you need for the 4472.
