Re: Automatic Brightness Control : was it ever implemented ??

Re: Automatic Brightness Control : was it ever implemented ??
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 ?

Re: 7a26 rise time
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

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
