I'am in need of a Analog Oscilloscope used but working for my personal use building circuits at my home so I can learn more about how they work . PLEASE HELP ME WITH THIS , THANK YOU

[Don Young]

I was going to buy one of those cheap digital Oscilloscope kits off of eBay but was told to check with this group and ask if anyone has a old working used Analog Oscilloscope that they would donate to me so I could test the circuits I have been building . I really like tinkering and have learned a lot in the past 2 years and a Oscilloscope would be my next piece of test equipment , but a new one is out of range for me but a used working old unit would be great for learning on . If anyone could help me I would greatly appreciate it . I Am disabled and working with electronics has opened a door for me that otherwise would leave me bored and doing nothing . I do not care if it is scratched or dented up as long as it is working , if anyone could help me , contact me at "FAKE NEWS" on You Tube (I do not open e-mails for fear of being hacked ) Thank you , Don Young ( looking forward to a reply and some help )

I hope this isn't too controversial. :)

I would recommend you get a guaranteed working Tek analog scope on
eBay, probably $100, $150 at most. The newer the better, but if it
is working when you get it, it will probably serve you long enough
to satisfy your needs.

DSOs are great once you have some familiarity with what to expect, but
can be very deceiving if you don't.

There are probably still some CROs finding their way onto the market as
people go digital.

Some of the test equipment brokers aren't too generous, but its worth
trawling through the ads in the back of various magazines.

There's a lot of non-bargains out there - but with a bit of effort you may
find a real gem.

What Sam says. Years ago I sought advice here and on the basic
electronics newsgroup for buying a used 'scope. The consensus was to
get a Tek 465B. I found one for about a $100.00. It still works great
and has always been trouble free.

My 465 was given to me free.

Every once in a while it needs a pat on the side to get it going.

Certain to be just a dry joint - but even with the manual, it wasn't obvious
how to get it open.

I looked on ebay and did not see anyting in that price range that I
would buy. There were some , but sold as is and not guranteed to work.
They probably will, but I would not take a chance on one if I did not
think I could repair it. Most did not have any probes either. Some
comming out of China are ok and you can get a pair for around $ 20.

I agree with the 465B scope, Probably the best analog scope for the
money. I bought one off ebay a few years ago, but it was over $ 200
without the probes. For that kind of money I would go to about $ 300
and get one of the China digital scopes.

How much money do you have to spend?
I bought a Rigol DS1052 for home use. ~$400 when I bought it... ~$330 now.
There are many who sing the praises of analog 'scopes. But for common daily
use a DSO is great... and the added features (FFT! storage..) are a real plus.
(I set up the 'scope with a microphone for my kids.. we then banged on the
piano and watched things in both the time domain and frequency domain at the same
time.. That was years ago.. I should do it again, they're older now.)

The digital scopes have came down. I bought a 200 mhz one for $ 299
shipped. Years ago I paid almost that for a used dual chanel 5 MHz
analog scope. Some are even less expensive.

Seems that many of them are rated in MHz and price. They are suspose to
be the same but different softwear. Sometimes the components are
slightly different.

YOu did not say what MHz yours is, but there are plenty of hacks on
youtube to upgrade them.

I am somewhat with the Craigslist crowd on this. Maybe eBay but shipping can be a bitch and a CRO could be damaged.

What people do not understand (maybe that is why the engineers over on SED don't want to pay new grads anythng ?) is that when you take a regular CRO down to very slow sweep speeds and then conect a battery to the test probe, even a five year old gains a certain appreciation for electricity. I have not see an DSO that can duplcate that, but I am sure they could de velope one if they got their eyes off of having the most useless features. And for a beginner, having a spectrum analyzer is useless, plus from what I hear many of them are linear scale. Without accurately depicting the octaves, what good are they ?

It might be a good idea to just go look for electronic surplus, and don't even look for a scope that is in pristeen condition. Learn to fix it and calibrate it by the seat of your pants so to speak. There should be places like HGR and ESI all over the place. It is just a matter of looking at the item description. Mainly you want it to have a trace, both channels. you need the vertical positioning controls to work, on both channels. that will pretty much clear any unobtainium ICs and whatnot in there. If it does not pass those tests then keep the mohey down. Offer like twenty bucks.

It is always best to go see the unit. some people are paranoid to go to strangers' houses but come on, if you are about to get robbed usually the deal is too good to be true. When you are around $50 or whatever, it is not a setup. And if you think it is, take a gun.

Take a paper clip or something to hit the V input on it and see if you can get that "hum" waveform, if so, that much the better. You should be able to synch into that. Watch the controls, like "synch source" for example. Do not poke the paper clip into the BNC connector, it will make it loose and it might be in a predicament that makes it very hard to change. Just hold it at the outside and make the electrical connection.

If you get that 60 Hz waveform and the scope will synch into it you are way over halfway there. Sure, there could be alot wrong with it but that is a different thing. When they are dead, or have no trace or whatever, that is when you really don't want to sink alot of money onto it.

I have three lower bandwidth scopes but I can't afford to be giving shit away. I might be able to hook you up with something in the mid range of CROs, my buddy has a couple of Teks around. One actually you can probably get reasonable is like a 465 or something, but it is a B or whatever, a bit rare. I think it moight have a hair more bandwidth. But it is supposed to have dual time base and that part is not working. I ran the problem down to the triggering (or retriggring) and kinda got lost there. But it works fine as a normal scope. Not sure what he wants for it but if you RSVP here I will ask.

Bottom line, the CRO is boss. I would consider a digital if they would make one actually REALLY emulate a CRO. All you digital scope folks, this is your chance to get a convert. Other than that, I am a CRO afficianado.

Right, I saw the same hack on Dave's EEVblog. I never bothered,
I've got faster 'scopes at work if I need one.
