use the scope to record the response and export it to a text file it is only a few minutes work to import the data to Excel and do the FFT there (using the Engineering tools add-in that comes with Excel, but is not automatically installed). Since...
E: Delay, this is used only in LTspice to move your signal within the plot window. Generating an Eye Diagram Mask In Part 1 of this article series, we described how to use drawing elements to display EMC limit lines over an FFT spectrum. In this article we show how to...
This area selects figures to plot and save as well as a number of data save settings.It only applies to the automatic version of SFRplus in Imatest Master (also EXE and DLLs) — it is not forRescharts. The leftmost checkboxes in this section select figures to plot and save. Note that...
which are stored by my logger software and imported into Excel. You can see that the frequency of the spike in the Fourier plot corresponds to the frequency of the original signal. (I’m doing a 1024-point FFT, which results in a frequency resolution of 15.625 Hz. So, in general, the...
