Hi Guys, What are the functional differences between the 1740 and 1740A? And, more importantly for me, are there any differences between the DB25 remote ports? Thanks, Stefan

Hey y'all, I've always been curious to see the applications that were available for my TDS784D back in the day. Have any of you even seen these applications, or know where I might find them? In the da

I don't suppose there are a bunch of plug-in extenders floating around, so looks like I need to build one. (I see one on ebay, but out of my price range) If I can locate a source of the connectors, it

Hi folks, I've been unable to chase down this knob for my 485. It's 366-1385-00. Similar to other knobs for this purpose, but with a "skirt" at the base, without which, it's more difficult to tell wha

I am looking for a front "clip-on" cover for a Tek2225 but they seem as rare as hens teeth - but it occurred to me that a cover from another scope in the 22xx range may fit. Can anyone suggest a likel
