Testing the TK Tar Baby

@TK

As someone who's spent a good chunk of the weekend tearing out my hair transferring VM's around, I'm content to give the benefit of the doubt.


I want to make it as easy as possible for RA to share the data she has committed to sharing, no strings.

Wow, I totally missed that "why should I fax anyone?" comment.

Gee, I don't know, because as the author of a paper you promote as factual it would be due diligence and demonstrative of integrity on your part?

Just guessing...

You'd need to guess.  You clearly have no CLUE.  If you doubt our presentations  then the ONUS is on you to DISPROVE them.  And ALLEGING conversations with LeCroy experts won't cut it.  Sadly.  You'd need to show conclusive proof.

And the rest of that statement is just nonsense. Especially since nobody can "let Ainslie know" about anything... her mind is already made up. She cannot even allow herself to THINK about things like FGs passing current, or the real use of AC coupling on a scope, because she already KNOWS the "truth" about those things.

Exactly.  I certainly do know the FACTS or the 'truth' as you and MileHigh put it.

Poynty?  Are you joining this bandwagon?  I expected better.

That video link  tells me that it's 'currently unavailable'.  And let me know how a square wave voltage generated at the gate has a DC coupled value.  it would be UNIQUE amongst square waves.  Golly.

Rosemary, I am simply posting a link on useful information and facts on the differences between AC and DC coupling in reference to the use of an oscilloscope.

Sorry the link doesn't work for you. It works for me.

Rose, every wave form has a DC component. The DC component is "0V" when the wave form is exactly symmetrical, such as would be the case with a 50% duty cycle square wave or sine wave, and the OFFSET is also set to "0V".

If the duty cycle and/or the offset is set to anything other than 50% or 0V respectively, the wave form will exhibit a DC component.

With reference to a MOSFET Gate drive, the absolute voltage level is paramount to know. Remember that it is the Gate-to-Source voltage that determines the Drain-to-Source behaviour (ON-characteristic) of the MOSFET. The Gate-to-Source voltage is unipolar (positive for N-channel), which means the Gate drive is actually pulsed-DC (a DC voltage that is ON and OFF), with some associated duty cycle.

It has been three month's since I asked this simple question regarding Q1.  You can insult and threaten all you want.  It will not change the facts and the data.

Everyone with basic 'scope skills can see what the voltage applied to Q1 is during the positive portion of the cycle and that no expected current is flowing.

First you attempted to tell us we were not factoring in the LeCroy's offset numbers.  Now you are sticking with this very silly AC coupling thing.  Anyone with basic 'scope skills knows just how silly this is.

There is a problem with Q1 in FIG3 and FIG7, and their associated "close-ups".  You arguing this point is like arguing that 1 plus 1 is not two. 

Keep digging, it is your hole...
