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)

P6015 refill with oil
R114 has an absolute permittivity/dielectric constant of ≈2 as a liquid and near 1 as a gas.
As a substitude for the R114 I used Shell-diala-s4-zx-i with a dielectric constant of 2.
The Probe body is modified as follow:
- cleaned in ultrasonic bath
- cleaned with isopropanol
- airfree filled with oil
The compensation box is modified as follow:
- C1: 47 pF ceramic capacitor parallel
- C2: 220 pF ceramic capacitor parallel
- C3: 220 pF polystyrene capacitor parallel
The P6015 is tested at 20 kV DC for 5 min.
oszillograms:
empty (1000 V peak) | oil filled without compensation (100 V peak) | oil filled with compensation (1000 V peak) | |
