Soviet Oscilloscopes (Made in USSR)

[schmitt trigger]

CMjones;

Coincidence? I believe it is Very unlikely.

Most likely, the Soviet designers decided to maintain Tek compatibility, such that they could install genuine Tek modules, if the need arose for whatever the reason.

[daxliniere]

Hey @imo, any chance you still have the schematics for your S1-99? (C1-99) I just got one for a bargain price and I have my doubts about the big electrolytics in the power supply being still usable (and not prone to bursting).

Thanks in advance!

By the way, my unit has an English front panel with Bull Electronics BE-2 printed on it. It does still say "C1-99" on the side and that's how I found this post.

Cheers everyone!

Bull Electronics! There's a name to conjure with. I wonder if it's the same company (J & N Bull) who used to advertise inside the front (or back) cover of the hobby electronics magazines advertising all sorts of surplus bargains, including their famous £1 "baker's dozen" packs. I still have some components bought from them, including one £1 pack which turned out to be a board from a Ferranti Pegasus computer, complete with valves.

To understand why the USSR copied technology, you need to know that in the USSR there was no intellectual property. Everything that was invented was done for the benefit of humanity, not for personal enrichment. There was no competition, just a socialist contest. Soviet engineers worked for a salary, sometimes received bonuses and awards, but did not become rich. All the engineers who conquered space and created the hydrogen bomb lived a little better than the road builders.

I think the KGB made quality of life more then just a little better for critical military designers to discourage defection to the west and espionage. I think you got past alot of bureaucracy, waiting lists, etc. You were taken care of in a ill functioning system. I noticed that people that had some sort of military/government ties in the USSR and Allies always had a better outlook of how it functioned, because the 'bugs' were worked out for them in a silent manner and they were near people (g-men) that could give you the best methods of dealing with a system that many felt was hostile towards progress (what to say, who to talk to, where to file papers, mannerisms, etc).

In the free world you just need to increase spending to allow for better outcomes.

[S. Petrukhin]

Where is the free world? Do you think the modern world is free? A world dominated by hucksters? Which suggest you rather-rather eat more-more. Do you have the freedom from the fact that the new processor is about to have 128 cores and you really-really need it? You have to work hard to be sure to buy it! Otherwise, there will be no happiness in your life. Do you think it is your free choice to pursue everything new and you are not inspired by the merchants?

The communists tried to create a system higher than the struggle for survival as in the wild. Unfortunately, people in the general mass were not able to live without fear and the whip. Having the opportunity to live in peace at any level of return to society, people in the USSR worked worse and worse, did not strive for quality, did not strive for development, with rare exceptions. Only the fear of being hungry can stimulate people. Only the possibility of capturing and defending territory moves society. These are animal instincts. Socialism and communism are utopias unattainable in human society.

Communism is not a utopia, it is a criminal system by law  and by people  experience in my country. Solidaryty movement swept it out for freedom, not for animal instinct.

To keep long story short, that CCCP utopia resulted that modern, developed in my coutry technology was prohibited by Moscow rulers, 'no' for computer faster than anything made in CCCP anytime, 'no' for public  communication infrastructure, 'no' high-tech factories, 'no' for modern cars, only alowed outdated soviet technology, produce what CCCP demands for CCCP needs - coal, steel, food ... local needs/development  completely neglected ...

Hydrogen bomb has polish-american roots. Soviet one was probly also 'copied' ...

Does anyone need food, coal, steel, and so on in the same volumes that the USSR bought? Is there much progress in free Poland now? The USSR bought up the products of the socialist camp countries in order for production to be loaded, so that people had jobs and money. Nobody needed these products, we had to use low-quality and backward products of former "friends". I remember the Polish radar at the airport, which worked steadily less often than the demonstrations took place. When it was thrown out and replaced with Czech, it became noticeably better. And there are many-many such examples. And for not being able to buy computers faster, say thank you to the United States. Let me remind you that there have always been sanctions for the USSR and the countries of the socialist camps, and among them was a ban on the sale of equipment.

Where are the most powerful technologies of free Poland and supercomputers now?  If you think less about your greatness, curse history and blame the USSR for all the troubles, if you understand that in all countries there are good and bad people, that talented engineers, for example, exist in any country, not only in Poland and in any country, it is not always easy for a talented engineer to find recognition now, you will find life easier.

And the bomb - of course, Russians stole from careless Americans and copied it. Moreover, finding errors and fundamentally changing the design to a completely different system of primary compression. By the way, I didn't know that Von Braun had Polish roots. I have heard that all people are descended from Ukrainians...   

And last week, backward Russians delivered astronauts to the ISS in 3 hours... This is not just to save time, this is a huge technological solution, which, by the way, has a dual purpose - it is a demonstration that our bears can shoot down any satellites with a balalaika.

This is technical forum, please do not polute it with political stories.
>Does anyone need food, coal, steel, and so on in the same volumes that the USSR bought? Is there much progress in free Poland now?

I think you are lacking  infomation and I know that it is hard to accept that dark time.  To illustrate different point of view between your and our view- coal was not bought by CCCP , coal was 'taken for free' This 'exploration' was so dramatic that  even polish comunists decided to resign from german compensation which CCCP was in charge to pay to Poland , after this CCCP agreed to stop that 'free exploration'. You can imagin how big this roberry was that even comunist government  (many were KGB agents ...) tried to stop this.

For second question -  yes, progress is visible everywhere in all fields, it is amazing how fast all is progressing.

Von Braun has no polish roots, but hydrogen bomb was not developed by him, but by two other scientists Edward Teller  and Stanislaw Ulman.

Russia and CCCP  has big contribution to space exploration, no question 
Btw we have also common scientists in that area like  polish-ukrainian-tatar-russian  Konstanty Ciolkowski.

How all this relate to CCCP scopes ? No, I will not respond for any political theread anymore, this is technical forum.

Just Scored a C1-93     is needs a little clean 

to Compliment my almost new C1-118

[Neper]

When the USSR broke apart and the Berlin Wall came down, West Germany was flooded with surplus radio and lab equipment from the East, much of it new or rarely used, all built like the proverbial battleship. Not latest state of the art but well made and rock-solid. No comparison to the cheap stuff that came from East Asia, at the time.

I was looking for a 2 channel scope and drove to the surplus store of Helmut Singer in Aachen to have a look at what was on offer. A new Russian scope, 2 channel, 50 megs? No prob. He waved to one of his employees to grab the pallet truck and get one from the warehouse. That guy returned with an enormous wooden crate, about 3 x 3 x 3 feet, called one his colleagues to bring two crowbars and 5 minutes later the scope was heaved on to the workbench and hooked up to the mains.

Long story short, I might have tolerated the noise of the fan, obviously made by Tupolev, but what really put me off was the picture tube, supposedly by Crayola. :-)

Shortly afterwards I got myself a re-worked Philips PM3219 50 MHz analog storage scope that just recently has been replaced by a Rigol digital scope.

Having said this, I still own a number of measuring and communications equipment from the USSR and East Germany and all of that works fine to this day.

I remember reading a comment from a Soviet researcher who said, "Unless the lab equipment was made for the Soviet military, it did not work well."

[madires]

Some of the Russian and East German T&M was also sold in West Germany, often rebranded by the importer. For example, Conrad was selling a few scopes made in East Germany under their VoltCraft brand, and Völkner was offering Soviet scopes under their original names.

[Pawelr98]

I own an S1-107 portable analog oscilloscope. 5MHz bandwidth on a single channel, yet it also has XY mode, with separate X input, multimeter functionality (values displayed on the screen) and can run off 220Vac/115Vac and 27VDC.
At 27VDC it draws around 0.5A while internal DC voltage levels under typical mains operation (30+V) allow to power it directly from an 7S Li-ion battery pack.

Hi!

Can anyone tell me the part no. in Cyrillic of the 4 way Russian in–line female connector that goes in the multimeter front panel plug of the C1–112A please?

Also, has anyone got a complete (Cyrillic will do!) Technical Book for the C1–112/C1–112A oscilloscope they can scan or point me in the direction of please?

The complete books have transformer winding specs and full parts lists in them, and I could do with the parts list, etc!

I've won a c1–112 on the evilbay with a suspect mains transformer, and if I can get the whole book, rather than the circuit on it's own, I can extract the transformer info from it!

Already have a copy of that - it's the actual copy of the original Cyrillic Technical Book I'm after for the parts lists !

Hi!

A helpful Member sent me a full German Manual and I found a full Cyrillic one after a few days searching on a Russian radio forum, so work on a brand–new full English Technical Manual has now been started!

The last page of the manual illustrates the two special tools that need to be manufactured for the collet knob fixings, and I attach my new drawings for them here!

First two new circuit sheets giving Block Diagrams in English also added!

Chris Williams

PS!

I missed off a link from the "Sign Trigger" block to the "Digit Unblanking Pulse Shaping" block in the second page of the "Circuit Diagram Sheets 1 and 2" attachment - I've now corrected and re-uploaded it!

[Chris56000]

Hi!

Circuit Diagram in English, Sheet 3, PCB Unit 1, Sync, Trigger, T.B. and X Amplifier for the C1-112A Oscilloscope!

Original Soviet–era circuit diagrams unfortunately do look very much like somebody has vomited all the сomonent symbols all over the page with no thought as to how to lay them out in a functional and workable manner, and I hope that my replacement diagrams fit the bill a little better in this respect!

Chris Williams

PS!

Diagram updated with minor corrections, additional notes and symbol details - please use this one for all future work!

I have this Soviet/Russian-made school-laboratory oscilloscope which is supposed to be used as “teaching aid in high schools and radio-amateur practice”. The model is H3017 (N3017) and was manufactured in 1990. Based on a poorly translated Instructions Manual it appears to be a 100 kHz scope (amplitude non-uniformity, referenced to 1 kHz: (i) 0-100 kHz +/-30%; (ii) 100-500 kHz +/-65%). The time base and y-channel amplitude potentiometers for fine adjustments are not calibrated/graduated, so accurate voltage and frequency measurements could not be performed with this scope. Only waveform shapes can be visualized.

The text-only translated Instructions Manual makes reference to block and schematic diagrams for this scope but I don’t have the original manual in Russian. I need to get a 120-230V step-up transformer before I could test the scope to see if it still works.

Does anyone have information about this model? Or, would anyone have access to the original Instructions Manual in Russian, including the diagrams?

Thanks!
