I need help to select the PXI card and supporting hardware to test the 0-25mA output signal from our device.

[Sumit35]

We have the product which is generating the 0-25mA output current.We are planning to test it from the NI.

We have NI PXI 6259 card (AI).would you please help us, how to test it 0-25mA output current with 6259 card?

You can just use a 500 Ohm resistor in parallel with your signal.  I would also add a buffer circuit to protect your DAQ.  Or you can do a quick search for isolated converters.

If this will be a product quality related measurement, you have to look at uncertainties and traceability (calibrations) ...

For a quick and dirty check any 500 Ohm resistor from (or underneath 😉 ) the bench will do it (0.5W better 1W) , otherwise you have to look for a stable low tempco resistor....
