Are you familiar with the high Q fixed value capacitors that were recommended for use with that Ring Down Q meter?
I think they were characterized for Q. If you know the Q of a cap, you can subtract it out of the total LC Q and know the
true coil Q. From there you could characterize other capacitors with a known true Q. Unless you have a Q over frequency graph,
you may still be stuck at only knowing Q at one frequency.
