Re: Coil Self Resonant Freq/Signal generator Question

["Kennan C Herrick" <kcha1@juno.com> (by way of Terry Fritz <twftesla@uswest.net>)]

The way I do it is with a signal generator, scope & counter:  Connect
generator & counter together so the counter reads the generator's
frequency.  From that node, drive the bottom of the coil via a low-value
resistor e.g. 1K.  Connect the scope to the 1K:coil node.  Tune the
generator for a max. on the scope and read the resonant frequency from
the counter.  ...and note how it varies when you move around the coil!
