7000 Overview Table

Hi, I've extended the table a bit, what do you say?

Is writing speed in cm/μs not a cleaner spec than div/μs?

Can you add the digitizers please?

Mostly I found div/µs, that's why I used it. but we can change it of course.
Done the digitizer. Kinda. Maybe they belong in another table with better fitting details (sample rate, resolution, etc.)
Barrytech said there is no R7704A http://www.barrytech.com/tektronix/tek7000/tekr7704.html. should we delete it?

checked in catalogs - the R7704 remained non-A and was available until 1985 -- Peter

about the 7603: what is "some" cooling? :-)

some models, as noted on the page --Peter

are you sure with the 7623B writing speed? should it not more like the 7633?

spec from 1991 catalog, p.68 --Peter

I love the table! I came here to mention that I have a 7704A with a cooling fan - but you also have the question re the 7603. The weirdest thing is that the 7704A service manual makes no mention of a fan! This led me down a bit of a rabbit hole of reading... I'd not be surprised if some 7603s had cooling fans. I thought that there might have been a period they tried some fans before Tek change from linear PSUs to the more efficient switching PSUs - I've found no data.

I've condensed the writing speed columns into two less, and added some of the missing data from my notes. --Peter (talk) 10:12, 21 September 2023 (PDT)

Looks a lot better! Thank you for your effort. --Rubasch (talk) 00:07, 22 September 2023 (PDT)

On the page 7000-series scopes there are production dates for the digitizers. But there is no source for that information... --Rubasch (talk) 10:59, 22 September 2023 (PDT)
