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?
- --Peter (talk) 08:11, 20 September 2023 (PDT)
- 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.

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)

What do think about condensing the information like in the example I have added above, 7623 (A,B)?
- --Peter (talk) 03:36, 19 October 2023 (PDT)
- I like it - but in that form, it loses a little bit of info where the 7623 with no suffix was available while the 7623A was also available - it's easy combining A and B by comma separating - but a null suffix... how would we show that? Hmmm - I tried (-) - just to show what I mean. Qfissler (talk) 04:48, 19 October 2023 (PDT)
- I also thought about combining scopes like the 7834--> 7934 but not sure if it still makes sense. Right now have not a lot of time for this. So everybody feel free to edit! --Rubasch (talk) 05:30, 19 October 2023 (PDT)
- We know from catalogs or announcements in ads, articles in TekScope etc. when new models came out. There is no comparable hard info on discontinuation - mostly this comes from models no longer appearing in catalogs. I think it is therefore not meaningful to infer from the model pages that there was any sort of overlap - at some time in 1991 you got a 7623B, whether there's a theoretical choice that you could have requested a 7623A as well is not substantiated by the information we have collected – therefore the box for the first year when the newer model came out would simply show that, i.e. 1991 shows "B". I also find the "(-)" symbol very awkward. The colored box says the model was available in that year, the fact that there is no suffix in that box says it's the base model. Thirdly, I would only combine suffixes, not different models. Just my opinion in the "keep it simple" spirit. --Peter (talk) 06:37, 19 October 2023 (PDT)

- Maybe also put the R-Versions in?
- Strange. As soon as I put this comment to the article, one row loses it colours (only) in the preview --13:07, 19 October 2023 (PDT)
- I think it's because that row uses CSS and fails in preview for me, too.Qfissler (talk) 15:24, 19 October 2023 (PDT)
- My idea was something more like the 7904 (sorry for messing up the table). Then the sorting by year would make more sense: which was the most expensive device in that year. You could see how prices develop. Problem: I used the prices "2022 Dollar". this will be no use in a few years. AND its a lot of work. So, any guess how the table can be kept up to date with litle work? Greetings --Rubasch (talk) 07:37, 25 October 2023 (PDT)
