Help with measuring voltage analog input with 7852R

[Biochemist_MU]

Hi,

I am trying to measure three voltage signals off a QPD, the three signals are connected to AI on SCB-68 and then I used the example vi for Acquiring Analog Input with FPGA R in the example finder. However, I am getting a range of very big numbers. I don't know how to convert those into volts or what are those numbers, units...etc.

Any help with that, please?

Thanks

Hi Biochemist_MU

Please take a look at the forum post entitled FPGA Analog Input and Output Scale.  It discusses the scaling for our R-Series cards.

Hope this helps and let us know if you have any more questions.
