Re: Right to Repair - Re: [TekScopes] Digital scope with CRT
When it comes to safes, like lock pick sets, there is a very real fear that less than honest folks will use the information for less than legal purposes. Now ask me about TE manufactures who keep

Re: Right to Repair - Re: [TekScopes] Digital scope with CRT
I've followed this topic with interest for a while now. I am not at the electronic level, circuit wise that most of you are. I have had a furnace controller go out over the years and unfortunately

Re: Tek 4654M; No Trace, No +5V, No +95V; Help
I checked F558 and to my surprise it was blown. I know I had checked it numerous times and it was okay. It must have blown during one of my probing expeditions. I noted with or without F558 the unit

Hi Nick, The error is probably indicating that insufficient horizontal waveform positions were filled during acquisition. Do you also have the calculator keyboard? If so, you can set the display in

Re: Tek 7854 intermittent issues
Check the power supplies for level and ripple. It looks like you have a mostly digital problem, and the digital side is more susceptible to noisy supplies than the analog. Dave Casey

Re: Reverse part lockups
Tgerbi, I'll put something together tonight when I get out of work at 11:00pm. My ABBYY come with a professional PDF software, OCR editor and a screen shot OCR capture. I some cases you have to do it

Re: Reverse part lockups
Dallas, Do you have some examples? I am always looking for better software. Don't know if I have seen anything specifically done with ABBYY software, since people usually don't say what they used.

Re: Reverse part lockups
Hello Tgerbic, Adobe never did well with ORC conversion, that's why I use ABBYY OCR software, The RPR lists on TekWiki converted perfectly. Abbyy OCR is not that expensive, paid about $150. Dallas

Re: Reverse part lockups
I have done a lot of scanning and OCRing (Adobe) and find the text is extremely dependent on the scan resolution and quality of the page. Text size matters and proportional spacing can be a problem.

Common design parts catalog vol 1 aka the yellow book. It's under manuals & catalogs / reference /components on the wiki . Not for model numbers, but good xref for 156 / 151 / 152 / silicon

Re: Successful TH720 battery re-build
Did anyone say ¡°put it in the Tek wiki¡± yet today? If anyone goes through with an 26650 (or 18650) Li-Ion hack, photos of that would be interesting to have in the wiki as well. Gr¨¹?e, Carsten
