Usage a NI-6224 as a ADC

[Scamper]

The question at hand is using a NI-6224 to measure an analog (DC signal) and using the ADC on board the NI-6224 to convert it to a 16-bit digital word/signal.  A task that was asked of me and believe that the NI-6224 is a data acquistion tool to move signals (analog or digital) from the outside world to LabView or vise-versa.  Please let me know if I am understanding the usage of this device.

Thanks

Sure, it can do that.  Check out the product page ( https://www.ni.com/en-us/support/model.pxi-6224.html )

It actually does the conversion to voltage for you, but if you really want the bits just multiply by ( 2^bits)/(Full Scale Voltage)  (for a 0 to n Volt signal) or

(Voltage +FullScale/2)*(2^bits)/(Full Scale Voltage) or something like that for (-n Volt to n volt signal).

That board also can do a lot more, using different pins.  Do you also have a terminal board such as the SCB-68 to connect your signals too?  (It connects to the 6224)

Yes I have the boards (I/O) that go with it, older TBX-68, but they will work.  So since you answered the question all I need to do is input the signal, assign the pin as the input the I select (digital or analog) then use the assistant to play with the signal.  I know that is a rough explaination but believe that is a good starting point.

Thanks for the reply and truly appreciate your answer.
