PXI 6289 Accuracy Calculations

[Bicbehr]

I'm trying to calculate the absolute accuracy of a 6289 reading using the formulas in the spec. In looking at the example on page 5 of the NI 628X specification the number at the bottom that is calculated for absolute accuracy is 980uV. Is that +/- 980 uv?

Bicbehr,

After searching our website a little bit, I believe it is +/- 980 uV.

Here is some documentation that might help you.

Thanks for the reply. I reviewed the same info on your website and think you are right.

AND don't forget the page 2 of the spec if you read more than one channel!!

Since the settling time error(s) are not covered in the these caculations.
