I will definitely grab all the captures you uploaded! |

Hello, a 10 MS (16 bit) file with 1 s from 1 kHz sinus. https://mega.nz/file/Re9VkQJR#HHbTFgsZAMDCldRT3S3wF6PWZqAiBuFDoB_ISOW82uA FFT from picoscope and FFT from octave Best regards egonotto PS.: Octave code clear load e:/sinus_1000_10M_16.mat; Length,RequestedLength,Tinterval,Tstart tr = linspace(0,(Length-1)*Tinterval,Length); ts = rot90(tr,1); t = flipud(ts); clear tr; clear ts; C = fft(A); D = 20*log10(abs(C)); D1 = D(1:10000,1); t1 = t(1:10000,1); plot(t1,D1); |

There are no constraints. Actually, creating the waveform software could be part of the curriculum. Here's a simple app I wrote to drive one of my Arbs. |
