[OBTAINED] Analog oscilloscope wanted under $100, 10+ MHz BW.

[DJKA]

Hi, I am looking for an used but working oscilloscope, I am EE beginner.  Dual trace one would be PERFECT!
Does anyone have to give away or sell for less than $100? My budget is really tight.
Thank you!

For you budget I think you should have a look locally. A

Also eday.de/ebay.uk has some cheap Hameg CROs. E.g:

Are there hamfest in your part of the world? If so I would start there.

The old Soviet military forces got rid of a lot of stuff when the USSR folded.
Some may still be around in your country,tucked away in someones back shed,or in an ordinary junk shop!
The hard bit may be finding out the specs of some of the old stuff,unless you can find a veteran who has used it.

The USSR folded about 20 years ago. So whatever was leftover is complete junk by now. I think the OP has a better chance looking at local hamfests and second hand websites.

[vk6zgo]

I Googled,& found a lot of people have old Soviet 'scopes still up & running,a lot more than I thought would be around.
Most of them aren't military though,apparently the USSR exported them,mainly,but not only, to the old Warsaw
Pact countries.
The ones I saw videos of seem quite nice units,maybe not Tektronix level,but certainly that of the later Telequipment stuff,or,dare I say it?---Philips!

My Tek 7613 & BWD 509 are both around 30 years old!
The BWD has a triggering problem,but otherwise works.

The main reason I suggested ex-military stuff is that it would be probably made to a higher level of reliability,though perhaps not performance.
He is more likely to find this kind of equipment at hamfests,as they would have been used in his country in the old days.

Hey, I bought some new scopes recently and have no more use for my old one.

It's an OS-5020 from the company  LG (there seem to be identical ones out there from EZ Digital).

The specs are:

20 MHz 6" CRT
1 Mohm 30 pF
2-Ch dual trance
horizontal: 0.2 s ... .2 us in 1-2-5 steps
vertical: 5 mV/div ... 20 V/div vertical sensitivity (can get down to 1 mV/div ... 1V/div with the 5 x amplifier switch)
rear connectors: Z-axis input and Ch1 output
10 x sweep magnification
X-Y mode,

link to the manual

Forgot the dimensions (60 x 60 x 30 cm I guess) of the box but it's fairly light (8 kg or so)

50 EUR + shipping?

[SeanB]

How much for shipping to ZA? I do not do Paypal, but can do a bank cheque to Finland.

[DJKA]

Hi!

Damn it! I've missed this one!
Well, I've never had a success getting a cheap scope from eBay(under $100 inc. shipping), but thanks anyway!
Have to be more keen on that!

Hi, this one looks fine, I reckon it's a good choice for me as for starter... Price is also OK, I am just curious about shipping cost.
Also, do you have probes included, if so what are the specs of those?

The Hameg sounds crappy. The seller says the pots are bad. You probably missed a box of grief 

How about this?

You seem to have a computer...

[Neganur]

Sent you an email. Shipping is 25 EUR as 10 kg international priority parcel  (http://www.posti.fi/english/pricesandinstructions/)

I may have two TT-LF 312 probes somewhere, they're neither new nor special and I may not be able to find the probe hooks anymore.  Specs are: 15 MHz(1x)/150 MHz(10x), switchable 10x/1x with 10...60 pF compensation range (http://www.testec.de/DL/TT/MA/LF312_EN.PDF).

How can they claim 48 MHz bandwidth while the sampling rate is 48 MHz?

Quite easy,they lie!

They can use equivalent time sampling which means a repetitive signal is sampled multiple times. Most of the older scopes that go up to many GHz have ADCs that sample at frequencies like 200kHz.

[Neganur]

Fair enough. I thought they meant single shot.

But at that level of operation it is only as good as a analog... On a device that must be coupled to a notebook, still smaller then a 100megger analog
