Hello again Raymond, A few notes on the CAL and fast rise pulses. 1/ Tek service manual CAL procedure is vague in a few places, see the notes from Chuck Harris on tekscopes2. 2/ since 1980s, we

Michael, Resistors: R1853, R1854, R1871, R1872 and R1880 are stressed. It is advised to make them 1W 1%. when these go bad, the focus will be off or not at all. R1991 is advised to replace with a 1%

To find the "where used" info, you need to refer to the RPR microfiche.

Congratulations! I meant High Drive Focus when I wrote (high intensity) focus. Raymond

When we closed our Electronics shop at the University, I bought a pallet full of stuff. In that, there was a small parts cabinet with drawers of components. About half appear to be Tektronix, many

The 2465B should keep focus when you turn up the intensity (at least you shouldn't need to change focus from low intensity to high intensity). Quote from the manual: "Focus tracking for intensity

Jim Williams used the phrase "verifying rise time capability" in relation to his pulser. In my opinion, often the meaning of this is misinterpreted. I'd like to present the most important (or maybe

Daniel, Note there's a dedicated Fluke group dealing with Fluke instrumentation specifically. May be worth taking this topic there. Radu. [email protected]> wrote:

Evan, I apologize for the late response. I can accurately measure the outside of a 79xx outer bezel. The depth of the?control s is something I hadn't thought about. I started looking for a Maker

I know this is a long shot, but doesn't hurt to ask. I want a P11 phosphor tube for my 570/575. I know the pitfalls of them vs regular green P1/P2/P31 phosphor for day to day use, but I still want

Jim WIlliams wrote at least one application note where he presents a pulse generator with ~350 ps rise times. I took a quick look through my collection of Linear Technology application notes and found

I have a few Tex 453 scopes. Two are oddballs in that they are MOD0703K so they differ a bit from the manuals available, although folks here pinted me at a doc that lists changes. The biggest

Although not 100% accurate schematics for the TDS400 series have been posted to the files section of this group as well as TekWiki. They were scanned from "C" and "D" size engineering drawings and

(Home made) tunnel diode generators obviously need very careful physical layout with minimal dimensions and preferably, checking and adjusting with a fast (sampling) 'scope. In my experience, S-52's

If you have CTT option the cal requires a precise 50% DC precise frequency and level. If no CTT option ignore Jon

Re-reading your message: Are you saying that when you need to use a high Intensity setting to achieve reasonable trace brightness because of low trace duty cycle/fastest hor. speeds, readout loses
