Very good video, thank you for passing on your knowledge of this beautiful oscilloscope tektronix 7603, I hope for new videos on your channel. I'm signing up now
20€ for a 7603?!? Is he kidding? The guy who sold it obviously didn't have a clue or was doing a huge favour. They usually go for 10x that (albeit working). That said, these are great scopes. Very flexible, well documented and pretty useful still. But difficult to calibrate (you need an unobtainium plug-in for proper calibration), and not cheap to expand either, particularly with some of the more specialised plug-ins. I have the 7D01 logic analyser and used it to revive my comatose Tek 4052. Of course there are far more capable analysers around nowadays, but it was a good intro for a n00b like me. The readout board can develop issues (mine had zeroes reduced to dots) and you'll have to hunt down the custom ICs, which I believe are diode array ROMs that define the characters (quite clever for early 70s tech, actually). I managed to get a replacement for a reasonable price, but YMMV. As mentioned, this thing is enormous and _very_ heavy; with plug-ins it easily exceeds 25kg. Absurdly, it's fitted with a carry handle -- I'm not sure if Tek was being serious when they included that in their design. If you plan on getting one of these, be prepared to sacrifice significant bench space -- and a few muscle fibres. 😉
Do you mean 7L13 spectrum analyzer? Anyway, I get all the Tek manuals from Tekwiki, it’s a fantastic site where you can find almost all manuals for Tektronix equipment
