Hello John,
                Perhaps I should elaborate a little on my original 
answer to this question:

I am looking at the stored ringdown/beat envelope of a *non-breakout*
waveform I captured and stored in the scope *right now*. The waveform 
was captured at 300BPS.
     Time to quench: <25uS   7 complete beat envelopes, Amplitude <25%
of first transfer at quench.
     Time between breaks: 3.33333333333 mS

Does that answer your question?
