WebSep 16, 2024 · In my example, I did so. Using the "Meas" command, I determined the duration of 1000 periods and calculated the signal frequency. Then I used the "Four" command and ran the calculation again and calculated the harmonics. I made a calculation for 100 periods. I also did an FFT analysis. WebThe LTspice directive becomes .tran 0 1m .9m. Explanation of the preceeding zero: The syntax is: .TRAN [Tstart [dTmax]] [modifiers] If Tstart or dTmax is specified, Tstep must has to be specified as well. Tstep is the plotting increment for the waveforms but is also used as an initial step-size guess.
