Detect phase difference using NI PCI 5401

Smiley HappyHi Forumer..

I'm newbie here... the situation is like this;

1) I have the NI PCI 5401 (digitizer/scope) and NI PCI 5112 (Function Gen)
2) Now I involve in bioimpedance measurement project where I inject current to the body via circuit and read back
   the voltage via circuit by using scope. My scope have two channel.
3) My friend doesn't design/have a circuit that can measure current to be feed into digitizer.
4) I don't have DMM (digital multimeter to measure current)

The question I want to ask is...

Is it possible to detect phase delay with scope with just one channel by just using RTSI trigger with func gen?

or

is there any connector with one SMB connector to 2 BNC connector so I can put one BNC to my friend circuit and another
to channel 1 on digitizer..

thank you... 🙂

Hi Jamaloogy,

If I understand your question correctly you are trying to synchronize the digitizer and the generator. I'm not sure what phase delay you want to measure though.

This previous Discussion Post talks about how to synchronize those two boards so I recommend you take a look at it.

Hope this helps. If I misunderstood your question please include more information about the phase delay you are trying to measure.
