Then maybe sparks you can build an device and show us how you do it .

   I am asking the question about what makes electrons move about a magnetic field line or a neucleus for that matter  because I DONT KNOW.  I do know that whatever force or combination of forces that govern unbound electron motion is an important thing to figure out.  So I"ll just keep on asking questions and researching until I know and then I'll tell everybody I possibly can as many times as I can what the fuck is going on.

     Back in the day I worked alot with unijunction triggering of scrs.  They were the fastest things around with the least drop.
The ujt would have to be heatsunk to last as it is purely a resitive element but if it picksup the field reversal and triggers the scr to shunt the reflection it may work as an active transient suppression device.  If it works I wouldn't waste the current on just heating though.  The ujt would act as a reversed field sensor and fire the scr into conduction until the transient voltage dropped below the holding voltage needed for scr conduction.

A short video showing the stability of one of the DDS modules.

A digital radio receiver is tuned into 40MHz LSB and we hear the audio tone of it heterodyning with the DDS module also set around 40MHz.

When a Tektronix FG504 undergoes the same test it falls rather short.

Sorry about the crappy video/audio quality.

   Nice oscillator I can see why you are worried about frying it.  No way to use optical isolation for your finals?

@Yucca!
That is one sweet setup and test with good solid results!
How are you going to synch or phase adj the 3 DDS60 units?
