What is the difference between buffered acquisition and non buffered acquisition?

[Flamboyant]

What is the difference between buffered acquisition and non buffered acquisition? How will I decide whether I want buffered acquisition or non buffered acquisition?

[Christian Mergl]

The difference is that you use a buffer or not.

So either you get a certain amount (maybe fixed size, maybe variable) with every iteration of your loop in software or you get just a single value (single point acquisition).

Very often you have to use buffered acquistion because of high sample rates or high channel count.

I will also add that with non buffered acquisition you have to use software timing. Windows is not a real time OS, so the the timing is not accurate. But if you use buffered acquisition the timing will be controlled with an accurate internal clock on the Daq unit. I think non buffered acquisition should be avoided in most cases.

No, you can e.g. use "1 Sample Hardware Timed".
