ADC Evaluation Library

python-adc-eval

A python-based ADC evaluation tool, suitable for standalone or library-based usage

Details

Package based on esynr3z/adc-eval

Tiny tools collection (Python NumPy+Matplotlib based) to do spectral analysis and calculate the key performance parameters of an ADC. Just collect some data from the ADC, specify basic ADC parameters and run analysis. See example.ipynb (you will need Jupyter Notebook to be installed).

Inspired by Linear Technology (now Analog Devices) PScope tool.

USAGE

To load the library in a module:

import adc_eval

Given an array of values representing the output of an ADC, the spectrum can be analyzed with the following:

import adc_eval

adc_eval.spectrum.analyze(<adc list>, <adc_bits>, <adc vref>, <adc fsamp>, window='hanning', no_plot=<True/False>)
