yokogawa goes 12 bit
« on: May 16, 2024, 09:44:34 am »
I came across this video from Yokogawa. It was apparently a livestream showcasing their new 12 bit DLM5000HD scopes:



There doesn't seem to be much about yokogawa scopes out there, much less of these 12 bit ones. Are they only big in japan? i really like their scope design, and they seem to be pretty high end, like on par with Rohde & Schwarz/Keysight/Tek, but they also seem to be pretty obscure, at least in the english-speaking world, why is that? hmmm!

Anyway, this scope looks really cool, too bad that they streamed from like 2005 and so you can't see too much of the 12 bit-ness in the video

They are also well-known here, they are professional suppliers, they don't have anything cheap in their range.
Prices are only available on request.
We have paperless data recorders and a 16 channel "oscilloscope" from them, the quality is excellent.
The DLM5000HD will also be excellent and has nothing to hide.
Down-to-earth data such as 500Mhz and max 2.5GSa/s, but 1Gpt memory - the ones from Yokogawa are simply analysis cracks.

You can have fun and ask for a price... ;)

a few years ago i came across their vertical layout scopes, and absolutely loved the design, but also couldn't find any reviews or anything out there, so i contacted them out of curiosity about where i could get one of those, and they also gave me a quote of ~8k usd for i think the 200MHz model?  :scared: but about this one, i'll pretend it's around the same to keep the daydreams alive :P

it would be fun to see a proper video review of one of their scopes.

this video from the olden times shows one of their vertical layout scopes in action, but it seems to be the only yokogawa scope review on youtube

I still have my DL1540 - which has ultra-nice handling and requires only limited desktop space. Plus it can be carried around like an old Macintosh. Can't beat that armada of selenoids clicking into the right settings :)
That thing is packed with electronics, they certainly know how to build advanced instruments.
Unfortunately, it is *loud*, so it got replaced by a Rigol. (Which is not silent either, but much more on the "OK"-level.)
Unfiortunately (2), these are very expensive, waaaay out of my budget.

Hi Folks,
             What a positive Yokogawa thread, other than the comments about visibility in the market outside of Japan. Hit's me hard as the person responsible for the distribution and marketing of the products within Australia and New Zealand.

Let me answer your question best I can. Yokogawa Oscilloscopes are not for the masses. They don't have a entry level point model, and don't go particularly high in bandwidth.  They are more designed for the power engineer. Yokogawa T&M is foremost a power measurement related company, DC, Low frequency AC, and Optical Power.  Available in 4 and more importantly 8 channel, Yokogawa  were the first to market with a 8 channel scope, and again I believe the first to market with a 8 Channel HD version.  Coming from a multi-vendor background I'm quite aware their are other options out there, but if Power is a concern, you will want 8 Channels, you will want deep memory, you will want a very high quality A/D frontend with low noise. What you won't want to hear (as has been mentioned) is the price, but the guys in precision power will know what I'm talking about.  You might also find the Yokogawa PX8000 an interesting unit, it's a older model, a hybrid of a  4 Ch Oscilloscope, and a 4 Ch power Analyzer, the later having 4 direct input current shunts allowing direct current input. Quite novel.

I'm a salesguy, please don't be too harsh. I'm not here trying to sell anything, only inform.

You could "inform" us of the nominal price, so we know how much of our lottery winnings to set aside...   ;)

I'm based in Australia, and you appear to be in the old dart ;) (England for those unsure)

If so, the DLM5000 series starts at around £12k and rise from there depending upon actual model and options, which are wide and varied. Guide pricing above is not for the latest HD 12Bit / 16Bit version.  You would need to check, with your local representative.

As for the brand reignition, it is amazing how many people ask me for a famous Japanese brand of car tire that is spelt and pronounced   
in a very similar way when enquiring about one of Yokogawa's fine products.  A bit cheeky from a newbie, but consider yourself "informed"  :-DD   

PS If there is enough interest I have no doubt I can get one in Dave's hands, but a teardown it shall not be, if you win the lottery, buy one yourself, and then and only then are we likely to see a teardown. Good luck ;)

It would be nice to have Dave take a go at a Yokogawa scope. In the Netherlands I do spot Yokogawa oscilloscopes in the wild occasionally. And not just the ones I own(ed).
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

yes! that would be really cool. i'm a fan of Yokogawa's look, so it would be really cool to see them in action and how they do against the offerings from R&S and Keysight, to see if it's not only got the looks!

The Netherlands, is actually home to Yokogawa Europe, where they have their lab with ISO17025 power accreditation run by a Gentleman that used to work for the Dutch NMI. I hope to visit on my next trip to Europe.  If Dave think's a review is in order I would speak with those that matter from a Yokogawa stand-point, and maybe you agitate your end. As a Newbie, I have limited sway vs 27k posts ;)

   It's good to have you onboard!  I've never used one of their scopes but I own several old Yokogawa analog meters and I can say that their build quality is absolutely first rate.  If price wasn't a consideration (LOL. That will be the day!), I would buy a Yokogawa scope in a heart beat. 

  Are the manuals for any of the Yokogawa scopes online? I'd like to take a look at the specifications and features.

Yes, they are online. Unfortunately, their datasheets are via their portal which you register to gain access. I'd rather it be a simple process, but hey I don't make the rules. The marketing stuff is much easier to see, and is still quite informative as attached.  Having just downloaded the user manual and Features guide, (both over the 8MB upload limit)

In name of decency a Gdrive link to the manual and features guide (40MB) - https://drive.google.com/drive/folders/1Fhv1yej6oLjFLvWWjfZInP5SICx0P8m9?usp=sharing

The DLM3000HD is out, and it looks so good. Too bad I could never justify the premium, maybe in 20 years on the used market! :palm:

people will respect your work because they see the yokogawa name working all over the place in the forms of controllers of various kinds. its not a object they expect to break

I think they have a reputation for not bullshitting data unlike some controllers


I associate them with temperature though.


Their power test equipment market grew because it got popular to "vet" low cost modules that are designed by chinese power supply companies for custom products, and companies need advanced testing for qualification for making basically any goods that use substantial amount of power. Its how you get lower prices then stuff like meanwell. Also, inverters.

And, for miniturization of power products, you can't use a module. They end up having strong requirements for form factor , meaning they need custom solutions for consumer products. I think other then PC's, the market did not really exist 20 years ago. For a global release you need really high confidence in cheap complex power goods meaning a shit load of advanced testing done on a continuous basis.... it still ends up very profitable despite the advanced test facilities. If you had manufacturing control, you don't need as much testing because you develop trust... with over seas suppliers you never really gain trust because anything can happen .

Yokogawa is notoriously known on the second hand market  for unavailability of service manuals for their test equipment, that is why no sane person was buying their used gear other than for parts scavenging.

I think that is a sales strategy to make it elite... so kind of like a fancy suit for your laboratories lol

I doubt it shows up much in academia because well, it does not really do anything better, or save you money, but it might 'convince' people

i never felt better about it over omega, just scared of what certain people with strong opinions might think. it seemed to be a way to close an avenue to 'quality improvement' harassment from bigger companies


I got annoyed by the prices, because it seemed not to fix anything that was actually happening, so the money was going essentially to shore up things that don't need shoring instead of shoring things that need shoring, but it seemed to keep the peace between certain parties, despite not really doing anything (aka not a design improvement or a manufacturing process change that resulted in increased output or reliability). What ever it was meant to improve or prevent, that fault would get picked up some where else, guaranteed, making it somewhat frivolous, because there were mad obvious problems that should have been focused on.. a mind numbing decision


so external quality people see a problem that is a problem in their rulebook, it has no effect really. we have problems that are obvious to us but the quality people are playing their guidebook and they don't see it, or its hard to understand. the result is buying alot of yokogawas and calling it a improvement...? i think of that more like paying for landscaping, ok its nice?


but there is another factor, there is just not that much competition with AC power analyzer scopes. its a solid option due to the market being as it is, but I don't feel that way about them on the PLC market. maybe is better if you have like hundreds of them and its crashing a giant assembly line. but for small amounts its hard to stomach that purchase (in cost/benefit). If there is a shit load of them the problem that can be started by a down PLC is so bad that its worth paying a shitload more. But unless you have people running around with carts full of PLC, I can't rationalize not just buying a spare omega! And for facotries they often want spares ANYWAY, so unless small downtime is absolutely not tolerable, you end up paying ALOT to have it in your ISO process. Like you can get written up for not having spares around in a inspection. So the reliability is almost moot unless its super bad or super sensitive.


but the bottom line is, yokogawa some how ends up being a solid choice for reasons of peoples opinion, which you can't get away from, even if its nuutty, given the status quo.. those clueless quality people are NOT going away lol

I got access to DLM3000. To this day I yet to figure out how to use the serial decoder, or if it is even usable at all.

Also, I see here they still retain the f*ck*ng annoying joystick center click as enter button. Missed the center? off you go clicking something else who knows what.
