I need the raw ADC output from a PCI-4462 using DAQmx
Is this possible or are only scaled engineering units availible.

There is a "Raw" version of DAQmx Read (see image). That is probably what you are looking for.

Alan,
one question to the 'raw':
Is this the real ADC raw?
How about internal filter, calibration,compensation, scale, gain, oversampling, ... all that stuff well packed into the FPGA/Asic to squeeze the last bit out of the hardware ?
If you set the range to 0-5V and choose U16 0xFFFF is expected to be 5V, but what was the ADC(!) output?

Henrik,
I think you will find the information here useful.

Thank you Burban,
is there something similar about the digitizer PXI-5922 and PXI-5124?
