Does anyone have any experience with Owon?

Just for kicks I ran a test to check the delay of the trigger out jack between the Owon SDS6062 and a LeCroy LT584L 1GHz scope.

I connected a cable from the the trigger out jack into channel 2 of the scope under test. Channel 1 was triggered from a fast rise pulse, the delay was measured from channel 1 to 2. The LeCroy showed 62nS of delay. The Owon showed 2uS of delay.

Many thanks to ALL of you who have replied to my thread. The amount of knowledge, feedback, and friendliness is, in my opinion, without equal across boards all over the internet. Thanks for the video, it was great.

I've also decided to go with the SDS6062 around Sept. 1. I hope it will go down in price by then but if it doesn't so be it. It seems like you have all made your case. I was kind of against getting the Rigol just because of the number of topics that have cropped up about it that were negative. It seems as though the scope itself is not that bad and even though the Rigol can be updated to a higher bandwidth, it seems that the resolution is lower than the Owon.

Thanks for all the information, advice, and replies. I appreciate all of it more than you know!

The 10 megapoint record length scope will capture 20mS worth of data (2nS X 10 million =20 million nS = 20mS). So you have a 20mS record with 2nS per point resolution.

right, this scope have max sampling rate of 500MSs...

I have attached a simple spread sheet where you can enter a scope sample rate and see the effects of maximum record capture time verses record length.

... but others might have different max. sampling rate while in long memory mode than in short memory.

In principle all low budget scopes sampling max. 500MSs within long mem and max sampling rate in short mem.,
even for the new "low budget" Hameg DSOs i didn't got ANY answer on the sampling rate while in long mem.

How the SDS7xxx/SDS8xxx are handling these 10M memory and on what sampling rate we don't know yet,
we have to wait for an review.

Found a review on the SDS6202 here:

https://www.mortoncontrols.com/blog/files/category-oscilloscopes.html

He also reviews several other of the competing scopes, well worth a read. In the photo, below, the Owon is the scope in the upper left hand side of the group.



EDIT: His review also shows that the ATTEN ADS1042CML scope can do a single channel split screen display of both a regular waveform and FFT, does anyone know if the HanTek DSO5202B can also do this?

The 'review' is not very good, it also about the usability and appearance, it has not one comparison of how good they are as measuring instruments, which is really what you want. 

That the review spends some time explaining what FFT is suggests he is not a technically versed person, and he even uses a Mac! .

LOL. I've seen some people use Windows and still manage to have some technical skills, so I guess a Mac user with a clue is possible .

I should not have written review, he only stated "first impressions". For me, that page is very good because I'm a novice to this subject and it does provide information, at my level, I am interested in.

Yes, I understand.  But, you'd really want to know the scope works as a scope you pay for, before anything else.  Its an important first impression of any test gear.  A technically minded person would immediate jump at the core functionality, just as with new PCs or mobos,  tech folks would appreciate a system benchmark test to determine overall speed.  What good is ergonomics if the scope measures unreliably or poorly?   Since the reviewer has all those models available, its a unique opportunity to compare if they are all functionally similar, or not.  A rise time or single 10MHz square wave response is all that's needed, and if all the scopes pass then what makes a difference between one scope and the next is mostly ergonomics, and that's what the extra costs are all about.

  Sorry for the stereotype, I couldn't resist, and its not good to stereotype anyway.  You're right of course.  After all Labview was first designed for Macs only and Mac OS-X is pretty much Mac favor of Unix.

Sorry to Hijack this forum, but my question is somewhat related to what was discussed earlier.


Do the OWON SDS scopes use the full 10M when displaying FFT?
and
Can FFT be displayed with the signal?
(all the screenshots I've seen show the FFT by itself awkwardly in the middle of the screen).
