Integral / differential non-linearity of the ADC

Postby Ilya Tsurin » Fri Dec 07, 2007 2:46 pm

Dear colleagues !
What kind of ADCs do You have in the data logging devices:
Wilkinson / Flash / Successive Approximation / ... Do You apply
a sliding scale linearization techniques to the latter types ?
Thank You for the answer, I.T.

Hello Ilya,

Do you have a specific application requirement?

Dear John ! My application will be a spectrum analyzer.

Differential non-linearity

Postby Ilya Tsurin » Fri Dec 07, 2007 4:09 pm

Hello John !
I've got an idea: i can measure the same amplitude with all available
channels (11) and then average the result - this would provide a
reasonably good smearing for gaps and spikes in my spectrum.

Does the PICO data logger have any analog buffers at the ADC inputs ?

Hello Ilya,

Which particular Data Logger did you have in mind or, is that a general question about our product range?

With regards to your spectrum analyser application, do you have specific performance requirements?

Regards
John
