How to simultaneously acquire data by PXI DAQ card

[sageliu@18053]

Hi all,

I’m trying to acquire a noise signal with the PXI-4464 card in our STS system (4 PXI chassis). I ran the NI example, selected two channels for simultaneous capture, but I get an error each time. When I click the red-circled dropdown, many options appear, and I’m unsure which one to choose. Any input from you would be appreciated.

You are using the example for synchronizing two different cards. Use the example for acquiring data from a single card and choose both AI channels as your input. The two channels will be synchronized.

As @mcduff explained, put all the required channels (even across cards) into the same session to synchronize them together.

Is this any case the T4 STS with massive amount of 4464 and 4463?

Please reach out over DM if you think I know what I am referring to.

Thanks for your advice. Yes, it is a T4 STS. When I click the drop-down button, many items appear. I just want to know which item is the correct one to select for the code.
