Hi All,
I apply a sine wave (1KHz, vp=400mA) in series with a dc source to my DUT. When I use the function of DFT in calculator to plot the spectrum at the input, I see a harmonic at 833Hz; and the frequency interval is 833Hz, why is that? For the DFT function, I do like this : dft( vin 0.2u 1.2m 1024 "rectangle" 1 1)
