New Zhiyuan ZDS2022 scope released

[ataradov]

I don't get it. Why do people even consider this thing when all documentation is in Chinese, but the prices are comparable to properly documented and warranted scopes?

What's so special about them? The company obviously does not want to sell to western markets, otherwise they would have bothered to have a site in English.

[pascal_sweden]

This company seems to make a lot of other test and measurement stuff

Yes, maybe only for the Chinese market, but still it is exciting to hear more about them,
and find out what they have.

Yes, they seem to have a site full of test gear. Or maybe they are into 3D-modleing test gear? No way to know really, unless you read Chinese

FFT implementation
===============

Here are some videos about their FFT implementation with 4M points:

Other cool videos

Many other cool videos can be found in the earlier provided link under the Chinese blue button:

Enjoy!

[ataradov]

Those "videos" are big ZIP archives of something. The download speed is abysmal, so I have no idea what's in the archives. Do they not know about YouTube, Vimeo and other video services? I assume some of them are banned in China, but surely there is a way to get around that. Or there must be Chinese video streaming service.

pascal_sweden, do you know Chinese, or just click random links until you get something interesting?

[pascal_sweden]

I don't know Chinese, but for the videos you can recognize English keywords in the description.
(E.g. UART, FFT, CAN, etc.)

The videos are in FLV format, and they play very nice with VideoLAN.

Really cool videos. Believe me! It's definitely worth the download.

Although they speak Chinese in the videos, they have very good details on the look&feel of the scope.
And I must say that the scope looks very responsive!

He's our forum ferret  , he hunts out all sorts of neat info to share with us.     

[nctnico]

Well finding a relatively cheap oscilloscope which works and has meaningfull features is much harder so even from that perspective it is worthwhile to investigate how well (or not) ZLG's scopes work.

[pascal_sweden]

I watched a few of their videos, and I believe that the protocol decoding is done in hardware,
as it is blazing fast!

This is really a strong contender
250Mpts memory, >330.000 waveforms/sec, FFT with 4M points, protocol decoding in hardware

It has support for many protocols, including RC5 and RC6 infrared protocols.
So, you no longer need to use your sound card for capturing and interpreting this stuff

Their 6 1/2 multimeter for 800 EUR is pretty neat too!

[Carrington]

I like what I see, these instruments looks very good.
And by the way, amazing PC software.

I found the following company information about ZLG, that I thought is good to share here:

http://toshiba.semicon-storage.com/us/product/microcomputer/designsupport/partner-list/partner-26.html

http://www.nxp.com/webapp/connect/displayPartnerProfile.sp?partnerId=1-BRTJ-16&tid=vanZLG

This confirms that ZLG is a professional company with a good reputation, and not just some new Chinese kid on the block

[Hydrawerk]

Why the hell do they copy that Rigol design when

[ataradov]

I don't see a copy. It looks like any other scope (with exception for LeCroy). If anything, it looks worse than Rigol, but it is mostly a matter of personal preference.

I'd like to see some independent reviews. Do they even sell them for real?

[ataradov]

Also, getting on that list of "partners" is very easy in many cases. I would not consider it a proof of anything. Company has been around for 15 years, but not a single product of that company ever got into hands of people willing to write a review? I smell BS.

Try and find a review of a recent Lecroy scope!

edit: BTW these scopes are rather expensive. $2250 for the 2 channel model with 56Mpts of memory to $4500 for the 4 channel model with a whopping 250Mpts of memory (all 200MHz bandwidth). This isn't exactly hobbyist territory. http://www.beststore-online.com/item?id=42027292068#81254081006

I'm not asking for recent. I'm not even asking for a scope. Any product released by this company in the recent 5 years will do.

There is lots of gear out there from reputable manufacturers for which you won't find a review.

There you have your reviews!

BTW: On Taobao.com these scopes range from ¥ 10.000 up to 20.000 = 1350 EUR up to 2700 EUR

There are also lots of crappy manufacturers. The thing is, we don't know. And they did absolutely nothing on western market. They may not be interested, but then why pursue them? Why do you want to even learn about the scope you can't buy?

You didn't see the link to the webshop I posted above? You can buy it for sure! What would worry me more is being able to return it if it turns out to be a buggy lemon.

[pascal_sweden]

I will contact ZLG tomorrow and ask them if they look for a distributor in Scandinavia and Benelux

Will keep you posted on my conversation! Stay tuned =)

[ataradov]

You can buy one,  of course.  Are you even sure it has English UI? All documentation and software is in Chinese.

[pascal_sweden]

Distributors don't buy stuff, but get free samples

That was addressed to nctnico, but I did that post from the phone with limited quoting ability.

Good luck getting a sample. Actually, good luck getting any reply to your request at all
