Some years back there was one "statistic" that was widely reported that

BTW: Both suppliers were american companies. The plant in England is

The real reason for the shortage is that any left overs can't be sold so
to maximize profits, they try to make just exactly the amount they expect

the government funds surplus production, this is the way it will be

Downstroke is firing. When ramp crosses threshold power device
(driving coil) turns on. So this crossing determines "dwell".

Device control is simple-minded (my preference ...

Device has three states:

Off... Fired
Saturated, coil charging
Current mode, regulated at 5.5Amp

So I only look at two conditions... when firing occurred was I in
saturation or in current regulation.

If device was in saturation, dwell didn't start soon enough so I
decrement the threshold. If device was in current regulation dwell
started too soon so I increment the threshold.

Worked like a champ.

Magnetic is what I'd do because it is cheap. A toroid coupler can be
made
for 50 cents. But for a DC-200MHz job this requires modulation or
sampling
before the transformer.

My understanding is that this is exactly how it's done -- modulation with
a
pretty high frequency carrier and recovery on the opposite side of a
transformer. I wouldn't be surprised if optical coupling were used to
provide the carrier reference to the isolated side.

Overall it's an impressively effective and _cheap_ way to accomplish the
task!

Yep, exactly. I asked because I just got one TPS2014 to try out at work. The
defining parameter for us is the capacitance to ground and for this scope is
should be fairly good

Bytheway it has a nice look to it and the battery mode is a nice feature one
normally pays dearly for

Here's the transcript (notice the repeated "yes"):

(Videotape, April 18, 1971):

MR. KERRY: There are all kinds of atrocities, and I would have to say
that, yes, yes, I committed the same kind of atrocities as thousands
of other soldiers have committed.

Note the "as thousands of other soldiers" and the fact that he did not say
that he committed "war crimes". He is confessing to being a part of
something he now regrets not confessing to any type of crime. It is very
clear.

The US doesn't have peasants. Most farmers are serious business people
nowadays; ignorant people don't last long as farmers.

You thought I literally meant peasants (and I really men serf, but for
some reason I like using the term peasant)?

I can site plenty of cases where Christians, and perhaps some Buddhists
(I'm not nearly as familiar with) promote one standard for the powerful
and another standard for the power-less.

Instantly Jerry Falwell and his doctrine of Christian forgiveness comes
to mind. Dr. Falwell teaches one should forgive even if admission
repentance is absent. However, it is moral and just for the state to use
the death penalty to punish crime. Gov. Bush (in Texas) refused many
pardons, even of one repentant Christian woman.

The standard and policy for the individual or small group of individuals
is inferior to the standard and policy applied to large groups and
representatives of large groups.

There is one standard for the aristocracy that wields political power,
another standard for those subject to their power. Somehow the label of
"government" confers a different standard of morality and conduct.

Besides the US is full of peasants. AFAIK, Most people do not own
capital assets. Most people use fiat paper currency, and are at the
mercy of those running the global monopoly game. And calling the mixed
economy a monopoly game is too charitable. The slaves on Uncle Sam's
plantation are chained with fiat currency.

I'm not sure I would agree to your definition of "pseudochristian"
because I don't think you know much about the Bible or contemporary
Christianity. Even if you can identify the foolishness of obeying a
degrading double-standard out of tradition, which is pervasive in
contemporary Christianity.

Would Jesus vote for a warmongering murderer?

Remember, Bush is a dangerous liar.

So is Kerry. I would think Jesus would be in Iraq, trying to get the
archaic natives to realize they are on top of 1/6th of the world's oil,
and someone is going to kick their ass and take it, or delegate the
violence to a 3rd party directly or indirectly, if they can't get their
acts together and use that immense wealth for their and their neighbors
good, rather than harm.

I think the only reason you know to bash Bush is that the leftist media
is, and the leftist media is because the socialist French, Germans,
Russians and Saps have gotten stiffed on all the money they loaned
Saddam to buy guns.

Why don't you find some good reasons to bash Bush so I can agree with you?

No, you didn't paraphrase, you rephrased, but even taking your
rephrased version. If he was involved that does not mean he was
guilty of war crimes. The victims were involved as were many US
troops who did not know at the time what was going on or did not have
the "mens rae" needed for their actions to be crimes. The guilt for
the war crimes that happened rests higher in the chain of command.

Of course,Kerry never reported any war crimes to the military while he was
IN the service(in Vietnam),and all the "vets" that were part of his Winter
Soldier testimony were found to be false.

There were a couple of cases where Kerry had either admitted or strongly

an admitted war criminal or a liar about very important issues.

I suggest that anyone who thinks there is a shred of truth to Dyson's

How is the isolation done inside the scope? Its quite cheap, around

All I've seen was a reference to magnetic coupling. Anybody see more?

Probably something similar to the now discontinued A6902 isolated probe
system.
They just incorporated it into a scope instead of a separate instrument and
all the extra cabling.
IIRC,they used a optocoupler with a magnetic thin-film transformer(for
isolated power supplies??),but I'm not 100% certain about that,not having
worked on any A6902s while at TEK.
