![]() ![]() I also recently got my hands on a nice THS720P, a fully isolated battery powered scope. I have somehow ended up with around 10 of the TDS500/600/700 series scopes, I really should sell a bunch and buy a TDS7000 series for some slightly newer fun. I have a TDS794D too that I got cheap and replaced some faulty RAM to get it working 100%, the 2GHz bandwidth is nice, but the inputs are a bit restrictive sometimes in real use. I usually turn to my 1GHz TDS784D when I need a digital scope with some real bandwidth though. I’m still trying to find a supplier of FSTN polarizer film to get them all working nice again so I can pass them on. I have 3 more in pieces with the common burnt polarizer issue on the LCD. I usually end up using my TDS220 for daily use, it’s compact, has the optional Maths Module, and 100MHz resolution so it does most of what I need when I just want to see a squiggly line. I have a 2467 and a 2467B as well but I tend not to fire them up too much as the CRT in those is delicate, and the later model digital scopes I have are more functional for most things. Useable bandwidth, lightweight and not toooo big, real knobs and dials and no waiting for it to boot up. Posted in Tool Hacks Tagged nostalgia, oscilloscope, tektronix Post navigation Picking a scope is a pretty personal affair, though, so one person’s great scope might be another person’s piece of junk. Then again, the new scope won’t have CRTs and exotic Tektronix parts to wear out, either. While you can get a modern scope for $200, it probably isn’t the same quality as a Tektronix. The shipping, of course, could potentially almost double the price. For example, we found several 2221s or 2221As for under $200 without looking hard. On the bright side, these scopes today are pretty affordable on the used market if you can find one that doesn’t need a repair with an exotic part. We loved these old scopes, although we also like having very capable scopes that don’t strain our backs to lift. You’ve got to wonder if the narrator understood what he was saying or if he was just reading from a script. Even if there was a Home Shopping Network in 1987, we doubt many of these would have been sold despite the assertion they were “low cost” - clearly a relative term in this case. We assume this was made to show at some trade show or the like. You can see it below and enjoy the glorious music and video production standards of the 1980s. We can’t remember ever seeing a late-night TV ad for oscilloscopes before but, for some reason, Tektronix did produce a video ad in 1987. ![]()
