Second Example PlugIn - Log-Log FFT Plot
A frequent requirement is to plot a frequency spectrum on two logarithmic scales. The instrument
provides a vertical scale, so CustomDSO has only to change the horizontal one. Here is an
example. The first figure has been truncated on the right side.
These examples were made with two different instrument setups: in the second, the FFT was
zoomed vertically. The graph has a red line to represent the theoretical envelope for the peaks.
This has great potential for testing the transmission characteristics of amplifiers and filters, since
the output can be compared with a theoretical curve. Furthermore, if the output is divided by the
