Favorite Tektronix Scope

I will second this line of thought. I have worked on both, and the 465's, and 475's are way easier to work on than the 453/454. The 465M is modular, and was designed to be serviced by military module swapping automatons.

And even easier still is the 2445, and 2465. The parts problem is a nuisance, but the scopes are wide open, and put together with the serviceman in mind. Not to mention the fact that there is no scope, of any vintage, that is nicer to use than a 2465.

OBTW, on my bench, you will find a 585A, 475, 2465, 7633/7D20..., and a 326.

I use deoxIt and progold (now DeoxIT GOLD) now since a friend of mine received it in an Agilent test equipment at work. I figure if it is spec'ed in there it must be the best. They have an interesting site, with lots of information and ways of using their products. I have a treo 650 which was not charging and communicating - a few wipes with Progold, oops deoxIT gold and everything is working perfectly now.

Emissions compliance testing.

What plug-ins?

When one of your scopes breaks. How will you fix it, without a second scope?

Yes indeed that's is very good purpose if for a spectrum analyser

A long time ago I purchased (in the UK) a spectrum probe useful between LF and 90 MHz meant for EMC testing in conjunction with a (if you wish as low as 1 MHz) oscilloscope. I find it a very useful instrument for homebrewing HF equipment ,although it is of course not a complete spectrum analyser .

Yep. A 2445 lets me do very nice things, like built in "caliper" kind of thing, triggering on selected signal, blah blah. It is a great all around scope for a dude like me.

I worked on an old Nicolet The switches were terrible, most all of them. I spent weeks trying to clean all the switches, mostly the rotary ones. I had to use all my toughest cleaners. The hardest part was getting into the partly sealed switches. I used my best cleaners, alcohol, Contaclean, Alcohol-Cramolin, Bufffrog cleaner. Over and over. I didn't use Deoxit, because I ran out. Cramolin is no longer sold as Cramolin. Its called Contaclean by the Cramolin Co. a German company. Available from InOne, Farnell.

If you part with that 475, then sooner or later you'll be very, very, very sorry.

I changed my mind. I will not sell my 475.

Now... I have little interest in homemade radio or audio stuff. So far my little forays into electronics centered around power electronics. Given that... Is there any possible reason to keep a spectrum analyzer?

Well said.

The 7603 is very nice. I use them for the spectrum analyser plug-ins as the bigger CRT helps. But for normal trouble shooting, I much prefer the

For smaller units, I prefer the 475. Nice and solid.

To complement the Tek 3052B digital scopes, I use 7904 with high speed plugins (like 7A19 and 7B92). The 7904 is the stand for the 3052B.

I use SC502 and SC504 in the TM500 racks when I want to watch something on the bench without taking up space.

Does anyone remember the "Jetronics" knockoffs of the Tektronix 'scopes?

When I was going to Army radar school in 1966 / 67, We used a Jetronics

The Jet was fine for school. Triggered sweep and good to at least 30 Mhz. Before I was drafted, all I had at home was a Simpson "Handiscope". Rated to 100 Khz, but would see a 262 kc. IF signal.

It's comforting to know that once I was assigned permanent duty at an Army missile site, all we used were Tektronix and Hickok 'scopes.

1. As others have said, when you need to fix your other scope. My 465 just took a dump a couple weeks ago. Used the 475 to troubleshoot it. One of the HV ceramic caps has excess leakage :( At least it's a replaceable part.
2. It's also nice to have a spare when the other scope goes down.

1. Sometimes you just need two scopes to do the job, especially when your project is divided up between two racks of equipment.

2. Sometimes you need multiple scopes because your events are asynchronous.

1. Some scopes are better at doing certain tasks like those nifty microchannel plate intensified scopes.

2. Sometimes you have multiple projects going and it's nice not having to disassemble your test setup.

1. You may have a 7000 mainframe, but need a portable scope like the

1. It's also nice to have a modern digital scope for slow events, math functions, and documentation. But, keep those analog scopes around as they convey more information about the signal at a glance than any digital scope I've used.

You also mentioned something about spectrum analyzers. Extremely handy for certain types of work. Depending on the anlyzer, they are great for characterizing filters, amplifiers, noise in low-level amplifiers, EMI issues, unwanted oscillations, impedance, and a host of other things.

Hi Blakely

I would like to correspond with you on some problems with a 141T.

My email is snipped-for-privacy@comcast.net.

Hi

Caig has DeOxit in 5% and 100% formula, the 5% works most of the time. You can get it in standard aerosol (hazmat ship fee ups) or the pump can D5P (no hazmat fees)

DeOxit is standard issue for Xerox service staff, our service lady told me about it, she is also a amateur radio operator like me.

I own some scopes. Though, my favorite is not one of Tek ones, but HP-1741A storage scope. Anyway, I realized that when I troubleshoot my scopes or fix something with them, I always got extra screws left. It is a bit annoying experience because I know those extra screw were being used somewhere. I think that test equipment are made of way too many extra screws.

It's probably a matter of total operating time instead of how old it is. I heard a story from an old analog engineer saying that when storage scopes were new, they were SO EXPENSIVE that you just couldn't keep them turned on, but only when you need to take a vital measurement you were allowed to turn it on. If that is true, I think some old storage scopes are actually bargains instead of to-be-avoied.

Switches in that environment

I owned one 454, and later used one 454A. The 454 seemed to comsume much more power than 454A. In winter, having the 454 closer was nice.
