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. |

Dear John ! My application will be a spectrum analyzer.

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 |
