Multi Channel Simultaneous DAQ

[nins]

I'm trying to acquire multiple analog voltage signals from a BNC-2090 DAQ device and read the data in different wave diagrams simulataneously. Specifically, each voltage is associated to a different channel. Is there a way to acquire, store and display this data in real time?

The BNC-2090 is not a DAQ device. It is an adapter to the DAQ card with BNC connections. Truly simultaneous data acquisition is possible if the DAQ board has a separate A/D for each channel. Most DAQ boards are multi-channel but they share a single A/D among all of the channels. There is a mux that switches between channels. The inter-channel delay is part of the specs of the DAQ board, so if you find the actual model number, that info can be obtained.

What software are you using for the data acquisition? Both LabVIEW and CVI ship with examples that show how to do what you're asking.
