Testing the TK Tar Baby

[Rosemary Ainslie]

And that wasnt the question I was referring to from Pico. Its the one about the transistor being bad/shorted and the scope showing it.

The question related to the transistor being bad/shorted as you put it - is the ONLY explanation that picowatt can use because there is no other reason for the current from the battery to be prevented.  Why don't you see this?  It's because the voltage signal at the gate is not strong enough - not positive enough -  that no current flows from the battery supply.  What picowatt is relying on is that since the voltage from the signal is strong then it should enable the flow of current from the batttery supply  His argument is that since there's no current then the MOSFET must have blown.  Either way he's trying to INFER that there's a misrepresentation in our claim.  He relies on this.

Why don't YOU show some due diligence and integrity and FAX LeCroy for your self and present their written reply?

If that is what it will take, I am sure someone can find the time to do this for you.

And again, even if the Q1 gate drive were 6 volts as you incorrectly state, why is Q1 not turning on?

Will you also claim that we are not reading the CSR trace correctly?

Thank you.  I see a glimmer of light.  You're acknowledging that your argument is PURE NONSENSE.  NOW.  Take it one step further.  Look at what happens when you apply the OFFSET.  If you're not sure then check out TK's videos.  Even he knows this  He showed it.  To us all.  THEN.  That's what's happened.  The offset takes the voltage lower yet.  You also SURELY are aware of this?  If not then go and learn something.

At least you have confirmed that you do understand the question.  The indicated gate drive IS more than sufficient to cause Q1 to turn fully on.  Yet the CSR trace does not show the current flow one would anticipate if Q1 were turned on.

So, yes, the question is why is Q1 not turning on?  Q1 must either be defeective or not connected as indicated by the schematic (Q1 can't have a DS short or lots of current would flow, so if it failed, it failed open circuit).

The reason people will "buy in" as you say is because the data is staring at all in the face.  The 'scope traces do not lie, and all can see from the schematic that if the gate of Q1 were to be made positive, current should flow and be indicated by the CSR trace.  The 'sope says +12 volts going to the Q1 gate.  Even your supposed 6 volts should turn it on more than sufficiently to show significant current flow.  FIG5 only shows around 6 volts being applied to the gate of Q1 and look at all that current flow as indicated by the CSR.

My dear picowatt

Why should I go to the trouble to faxing anyone at all?  To convince you?  Or to convince the likes of Mags?  I think what would be much more appropriate is that - before you rather recklessly and slanderously made claims as to the performance of our apparatus or to the measurements from our instruments  - that you acted as a professional and CHECKED OUT THE FACTS for yourself.  As it is you've been spinning these confusions and misdirections with no application of moderation or with any professional constraint.  And you pretend that you're 'harmless'.  You're toxic.
