linearity in the vertical scale of Picoscope 4424

Postby Guest » Fri Jan 30, 2009 7:17 am

The data sheet says that the DC accuracy of the vertical scale of Picoscope 4424 is 1%FS, but not mentions the linearity and reproducibility. Accuracy of 1%FS is sufficient, if the linearity of 12 bits and the reproduciibility of 1LSB are assured. However, if they are not given, one can say nothing about differences smaller than 1%FS when comparing two wavelets. Culd you give them :?:

Hi, we do not have any figures, however having spoken to the engineer he estimates the linearity to be better than about 2 counts.

Hope this helps.
