Reducing sample rate oscilloscope

Hi, I would like to design a FIR-filter for the input signal of the Moku:Go oscilloscope. The problem is that the sample rate of 125MSa/s is too big for the Matlab filter designer. So, can the sample rate be reduced somehow?

Thanks, Tim

Hi Tim,

are you using Moku Cloud Compile to implement a MATLAB designed filter ? If so, the input sample rate for the MCC slot is 31.25 MHz. Is that suitable ? If not, you could implement a decimator in MATLAB.

Also, in case you have not noticed, Moku:Go includes a FIR filter box instrument that might be useful for you to filter before the oscilloscope - see attached.
