Testing the TK Tar Baby

@MH: it seems to me that from what you are saying that the currents in the CVR are tiny during the oscillations. They certainly look to me to be quite symmetrical plus/minus wise, even though they can have high apparant peak values of several amps or more. But even in the greatest negative power product claimed by Ainslie, these oscillations on the CVR trace are never extremely asymmetrical about the zero line. A few percent at most, usually much less as far as I can tell.

So it's really really hard for me to see just how that SCRN0235 could possibly average to 50 Watts, since the power is so high-- 5 amps x 73 volts -- for 45 percent of the time. The other 55 percent of  the time the current must be well over 2 Amps in the other direction, for the average to wind up at 50 Watts.

I'd really really like for someone to show me the complete chain of reasoning and calculation that leads to the 50 Watts average. And if the answer is "you take one number in the box and multiply it by the other number in the other box"... well...  I dunno. Can a person die of flabbergastment? I think the true average power is quite a bit higher, but of course I'm always willing to be SHOWN where my errors are... so that I can correct them.

Golly. Guys..... slander. Libel! TRADUCEMENT !!! LOL....

@MH: Timing skew? Now how could that be. Doesn't the LeCroy have a deskew function?  Oh.... yes, I see that it DOES.
But if there is a timing skew and the scope's deskew function isn't used to compensate for it.... doesn't that affect the ACCURACY of the math that is being performed by the scope?

But why are we talking about "averaging" anyway? No self respecting scientist would ever use AVERAGING on a switched circuit.

I just can't figure out what they DO use..... because it sure looks like averaging to me. And I can't figure out whether Ainslie is FOR or AGAINST averaging.... this week.

Why, if averaging is bad, do all these scope traces show means? Isn't a "mean" an average? Or does "mean" not mean mean but mean something other than "mean" which is defined as the arithmetic average? To contrast it with median and mode, the two other measures of central tendency?

Well... at least we can tell that the "deskew" function was NOT used for this trace. But where do these turnips come from? I'd really like to know the explanation for these envelopes. I have seen nothing like them, but I have an idea how they might be reproduced.
