Re: measuring Capacitance or Inductance


 

On second thought, forget it. Those of us who have been there, done that
know better. I have a well outfitted RF lab covering to 21 GHz and know
how to use the equipment. I'm through replying to your posts. Go find
someone else to flame......

OK. I'm stupid and really don't know what I'm talking about. I spread
snake oil, saucery, witchcraft, and magic as applied to RF. Smith charts
are just disguised wiggie boards. And, of course, the earth is flat and
all celestial movements are determined by epicycles and epispheres. I
spent 10 years in RF design and the last 30 in EMC/RFI. Color me stupid,
dumb, incapable of handling DC Ohm's Law and don't know which end of the
soldering pen to grab.

I do not appreciate being attacked for my posts. I am working on data and
will post to this group.

Electrolytic, tantalums do NOT make good bypasses for high frequencies. I
proved that to myself decades ago in RF design and following in control of
EMC/RFI. Go build a preamp using only SMD 'electrolytics'. Control RF
emission of a ?P ringing at 3.6 GHz with only SMD 'electrolytics'. I am
taking data on that and will present it to this group. Please hold off on
flaming me further until that work is complete?

Forgot to ask, what's this legendary piece of equipment,
it has transistors so it can't be that good ?

Yeah, I remembered that about the one on the left after I sent the
pic.
The one on the right he called a "buzz kill".

The left hand one is bypassed with a .01 so that doesn't count. I

puzzled by the other one; what's it supposed to do?
