Finding a card or cards that allow different scan rates for different channels

[bear956]

I was told that my SCB-68 card did not allow multiple scan rates for different channels. I was wondering what card or cards need to be connected to do this? It may require getting just one more advanced card. I am using LabVIEW to create an application that measures voltage and other stuff.

I have just started using LabVIEW this week and I am really in the dark on this subject.

I'm not aware of any stock cards that allow this function. However, is there any particular reason why over-scanning your "slower" channel/channels is a problem? You can always through out the extraneous data. I've always been of the opinion that it's better to HAVE the data than to WISH you had it! :=) I'd just set your card to scan at the rate necessary to collect your fastest channel, and let the slower channels just collect the extra data points.

Just a thought.
