I have a 7J20. Unfortunately, I don't have the sampling head. I've had it for a long time, and when I got it, I knew it was uncommon, but I figured a sampling head would eventually turn up. No such

In an over-the-counter repair shop, this would be sage advice, and I'm not sure I'd take you up on that bet. I believe Vincent is, however, more interested in the journey than the destination, and by

Early on e.g. 1960's, WD-40 used fish oil. It changed to petroleum around the 1970s when fish oil became more valuable as a food supplement. That has not stopped the salmon fishermen out here from

That's not too surprising. The only inverter input where it is reasonable to do is the 1-2 inverter. The input there is weakly biased, rather than being positively driven from another logic

I think now I understand what you asked me to do. If you were referring to these wave forms shown before the CRT section I should be expecting at different points, I don’t. Point 87 (J6-10) and 88

HI! A german Tektronix fan constructed three plugins: 1) RO510 10MHz Rubidium Oszillator. Two protoypes were built. http://w140.com/tekwiki/wiki/RO510 2) DP512: A 12GHz 1:1000 prescaler. One

I’m not sure about folks outside of the US but if it were me I’d take a side panel down to the paint store and have them color match it. I’ve used this method on my house where it works well,

I believe at one time a company called Spectracom built a TM500 rubidium frequency standard plug-in.

Yes, and no... You know what the values should be, and you know relatively where they exist in the calibration file, but you have no idea how, or where, they exist in the 2K RAM. Tektronix went out

I am interested in the 7J20/J20 for light source spectrometry. I have an Ocean Optics fiber-optic one that works for what I usually need, but hey, one that works with my Tek 7000-series scopes would

What exactly don't you understand about the Bluebase 79126 reference? I am guessing here, but I think you might have a difficulty in understanding the technology of making a particular color

It takes a brave person to admit to liking and using an 11k-series scope :) I have a couple and "like" them in remote-controlled applications, but hands-on operation is a different matter. The

Here’s a quick review of what’s important to know about the wide assortment of scopes and scope features available today. https://prezhost.com/2020/06/25/how-to-select-an-oscilloscope/

Hi guys! I opened exerciser 2 on my scope and copied all the data from 00 to ff by looping through all of them as I was recording a video. If I input the said data in my programmer and flash a new

There has been communication on Tek blue paint ever since I joined this Forum. May I respectfully suggest that you have a search through the past posts to find all you can. There is a lot of

Hi Dave, Abc Xyz did not report back so far, so the scope can be yours. I will send you a PM to clarify details. Chris @Abc Xyz: Sorry, but even in 'modern' times where salutations and signatures in

I notice something I didn’t pay attention to before. That is TP1486 should go from 15V to 75V depending on the position of the Intensity control knob. However, mine goes from 15V to only 31V with

Hi to All, Inspired by the 7J20 and J20 scarcity remarks.There are other items. Seldom seen. Sometimes only once. Recently many overpriced 067-XXXX-99 Fixtures pop up on eBay and also TekWiki has a

I think if you find one of those, that it will be protected by unicorns. According to Dennis Tillman in TekWiki, there were only about 40 made. If I understand correctly from past discussion on this
