Re: [TCML] Bipolar tesla coil
The spectrum was computed from observed secondary voltage, by means of the
buildt-in FFT feature of my Tektronix TDS2024B digital storage scope. In my
little report you can see the corresponding screenshot on page 21 (center of
page). The screenshot is also giving an .csv-file in higher resolution (2500
samples/shot), which was used in an Excel, in order to generate the diagram
at the bottom page 20. The secondary voltage waveforms were taken by means
of a Terry Fritz "plane wave antenna". Thanks for your comment.

Neat setup. Unfortunately I can't read German and have a question about
the 'double-humped' spectrum at the bottom page 20. Was this measured
with a spectrum analyzer, computed from observed secondary voltage, or
something else?

This coil can easily also be converted from a halfwave- to a quarterwave
TC.
Merry Christmas to all.
