The sampling frequency is too low to detect a 130 Hz vibration:
A = readmatrix('DutyCylce82Vals2.csv');
A(:,1) = A(:,1)*1E-3; % Convert To Seconds
Ts1 = mean(diff(A(:,1)));
Fs1 = 1/Ts1;
This calculates the mean sampling frequency (note that the signal is also not regulalrly sampled, and it needs to be) to be about 41 Hz. In order to detect a 130 Hz vibration, the sampling frequency must be at least 260 Hz (sampling interval at most 3.84 ms), and ideally much higher than that, for example 300 Hz, with a sampling frequency of 3.33 ms.
