Multifunction DAQ

[Aneece]

Dear Ni Experts,

I am trying to display an electric signal on personal PC that converted from a photdiode through third party conditioning signal board, can I interface this signla with basic DAQ PCI-6251. the third party board already have shielded cable 68 pin.

Your help greatly appreciated.

Thanks

Hello Aneece, Have you found the answer to your question yet? If not then can you give some specific details on the signal coming out of the third party board please? Thanks, Alistair

Hello Ali,

the signal that I would aquire it is coming from a photodector, the photodetector is being connected to an amplifier/signal conditioning.

As long as the voltage to the DAQ card is within -10V to +10V, you are fine.  We use op-amps to perform signal conditioning before sending the signals to the DAQ cards.

Thanks crossrulz for the reply, the problem I couldn't manage to know the model of the signal conditioning board that already connected to the photodiode.
