Dear Moku Support Team,
I recently came across the ADC input noise plot for Moku:Pro (attached below for reference). I would like to reproduce a similar plot on my own Moku:Pro device to evaluate the noise performance of its analog front end.
Thank you,
Xiangyu
Hello @xiangyuwei ,
Thank you for reaching out! The method we used to produce this plot was to terminate the input with a 50 Ω termination resistor and start the Data Logger. Then, you will have to take a few different measurements at different sample rates in order to get the whole span (i.e. 100 Hz, 20 kHz, 2.5 MHz, etc). Then, you can just stitch all of this data together and perform ASD analysis. We used MATLAB’s pwelch function to calculate this and plot it on a log-log scale. I hope this helps!
