Functionality of DAQ

[R_J]

Dear All

I wants to know how the DAQ card works. Like how the analog output , DO signals are generated. How DAQ captures the data.And when we changes the Sampling rate or number of samples etc., these changes internally effect which part of the DAQ card. How the counter generates the pulses.

If anyone is having any document releated to this then please share the document.

Thanks & Regards

Hi J,

Thank you for posting to the NI forums.

Which DAQ device are you using?  Assuming that you are using an E-Series (60xx) or an M-Series (62xx) device, I have placed the user manual for these product families below.

These manuals have detailed information about the theories of peration oof the internal workings of these devices.  In addition, check out the following tutorial describing common DAQmx function calls.
