How to connect the PFI interfaces to oscilloscope?

[su27]

I have a BNC-2110 connector board. I want to display PFI0 signal by oscilloscope. How can I attach this signal to oscilloscope? Just by a normal copper wire or some gadgets from NI. I am a freshman to DAQ.

Any information would be welcome.

Thanks

Hello,

For most cases that is correct you just have to wire the output of the connector board to the oscilloscope. Bare in mind the sample rate,input impedance and voltage range of the oscilloscope if you are generating high frequency/voltage/fast switching signals.

L.E.: Also you might have 2 different grounds in this circuit which may give you erroneous data, the last graph in this shows what I am referring to so take this also into consideration.
