Hi Chuck, Thanks for that... didn't occur to me :-( So in short, the patents that Tek filed originally with the intent of PROTECTING themselves... is 20 years down the line playing AGAINST them ?

Hi Vincent, It is all much easier to understand if you are a money grubbing, scoundrel thief. In a word, the reason they won't make the information available: lawyers. If they show you the source code

Fabio. There is no way a simple 33 ohm resistor could cause that... pshhh... HAHA. Nice job!! /g/TekScopes/photo/49370/7?p=Name,,,20,1,0,0

Yeah, I am not a librarian so if you say it costs so much to stock all their paper/printed manuals.. well you certainly know what you are talking about, it's your area of expertise after all, dealing

Just made a little donation (35, not a US citizen so not tax deductible...), every little helps. Been a month and a half and I see only 90 people donated ? Despite the important number of members on

Hello Lop Pol, Well... Attenuator blocks are not really swapable "Plug-andPlay" as they are usually adjusted to match each 7A26's input capacitance... But, since the behavior is consistent and the

When I replaced the bottom half of the probe body, the replacement part did not have an opening to allow adjustment of the DC offset Trimmer. I disassembled the probe and drilled 1/8" hole in the

Hello, I didn't see that you got a reply to your fan mount question yet so let me 'take a swing' at it. The manual for the 180A does not show us a picture of the fan mounts, but they might be the

If it's only happening on the 20mV/div setting, it's probably something to do with the attenuator compensation capacitors. These are also prone to problems, though I've found that it's not so much the

But you must pay close attention to your return address or you will end up sending mail from the wrong address. Ask me how I know. I have 3 e-mail addresses with Yahoo and I use Thunderbird as my

Messing around today after i THOUGHT i had things straighted out, I was looking at the rise time again and 50mV is good 10mV is fine but now 20 mV only has horrible rise time. Do you guys think that

You can use more than one Email program at a time. Michael A. Terrell

There is more than one way to skin a cat. Actually one could just open a new email account just for this group and possibly a very few other things. Problem there is logging out of one and on to the

The battery powered scope is actually floating the scope, but they are designed for that. Even if not they will be quite tolerant of it. In the case of your LED example, one could only hope that

OK, going back to basics, the scope has two channels, which may be added

Hi Nielsen, Just to clarify my experiences when using "CH1 + CH2 Inverted" I was never floating anything. I would consider that to be dangerous and not a valid or approved use of the ADD function of a

One more thing - the add and invert functions have been included in many scopes over a very long time. You should read the manual - it likely has instructions and examples of making simple

Without rehashing this whole thing, just change your thought picture terminology from "add/invert" to "subtract" - that's what a differential amplifier does. The issue is, how well that subtraction is

I see that I need to clarify further. I thought the topic would be enough, but I should have been more specific, from the replies this topic has received. I wasn't aware what scope I was referring to
