I am trying to view the 800 Hz tone of the MMIC2 EVAL board with the setup described as in the user manual. I can't seem to replicate the plot shown in the evaluation window successfully in MATLAB. I exported the data as a CSV file, read this into MATLAB and took the FFT. The power on the y-axis is off and i am unable to narrow the window enough to view the 800 Hz peak. Any help would be greatly appreciated.
