Cheap Oscilloscope? Voltcraft DSO-3062C

[h0nk]

The upper plot is for trigger only.

The white plots are 'reference'-plots. Look for: Save/Recall -> Ref -> Save.
Dont forget that You have to recall the plots also to make them visible.
The scope has two of them: RefA and RefB.

So You make Your first measurment, save this as reference.
Then You modify the parameter of interest and can see the both measurments on the screen.

Hope this helps.


Best Regards

Very interesting thread.

I have ordered a Voltcraft DSO-1062D for 329€ and will report as soon as it arrives if the patch to 200 MHz works without problems.

Should be a very cheap and reliable 200 Mhz digital storage scope for my home lab if all the reviews that can be found on the net are true.

Keep your fingers crossed ...

It is a nice price. The 3062C was *the* absolute scope bargain at 269 euros vat and shipping included.

The fpga in the 1062D may be either older or newer than the one in 3062C according to reports on eevblog. Please let us know what you got and your experiences.

Very interesting thread.

It is nice to have an user club on sonsivri, but be sure to check out the thread on eevblog as well. Most of the information here originates from there.

all these cheap oscilloscope seem toy:

I bought this model a couple of years ago.

I wanted to use it as a cheap portable oscilloscope when I am working outdoors. Never had any problems, I would recommend it.

If i understood everything correctly you can change the FPGA design (not the physical FPGA) "at will" by just loading another design file into the scope which will be used from next boot on.

There is also a very long thread (in german) about all this here:
www.mikrocontroller.net/topic/249628

and here:
www.mikrocontroller.net/topic/205820

As soon as i have got the scope i will try some of the modifications and report here hoping to help others who are also interested in a cheap storage scope.

I have canceled the purchase of the Voltcraft DSO1062D in Conrad, long before they could send it to me. And just an hour after it was sent by DHL they tell me that I can not return, because they have already sent it. 

Any advice is welcome.

Check their written cancellation and return policy.  You are probably bound to that policy unless you local consumer protection laws state otherwise and give you additional rights.

Sometimes people refuse shipments when the carrier arrives.  I don't know if that is actually a good idea to try or not, nor what the laws governing that behavior would be.

It is not uncommon to have difficulty canceling items from companies that have large or complex operations even if you think you are cancelling well before they ship.  They don't always have a mechanism internally for stopping an order once it's gotten beyond a certain point.

In NL there is a 7 day cool-off period for internet purchases if the purchase is done by a private person, not when ordered as a business purchase. Don't know which country you're in.

If you accept the parcel, you probably end up paying for the costs of returning it. As Gallymimu said, check your local cancellation and return policy.

I do very little business with conrad, but the times I had contact with them I found them friendly and forthcoming.

[Armageddon]

Today Conrad sent me an email, asking me refuse shipments when the carrier arrives, and I did. Without costs of returning it.  
But the money is not returned to me in a month...

The truth is that after viewing the electrical schematic and the ADC datasheets Voltcraft has stopped like me.
This is gonna sound a bit silly, almost I prefer Owon, despite its poor internal construction.
Specifically this model SD8102, among other things, because the ADC MXT2001 is a clone of the adc08d1000, ENOB is 7.3 (TYP) @ 498 and 248 MHz.
The input stage on owon has good A.O, great BW. Memory and sample rate are OK (see attached).
Additionally the manufacturer (owon) has been correcting firmware failures. And if price is around 400 €.

What is your opinion?

[sarah90]

Your first attachment refers to the hw1005 of the hanteks, which were ancient and badly broken.

I don't think there is a pure winner in this low end scope arena. Why not skipping these old models, and go for the new 2000 series of rigol?

Or do yourself a real favour and buy an agilent.

Note: If I were to choose one of these for free would not be the Owon.

Agilent will cost you TWO organs for a new Scope and only ONE organ for a refurb ebay deal.

I vote also Rigol, very solid product for the price (not the best ENOB) My only regret is I should have paid a little more and got the Mixed signal version with 16 channels of logic analyzer built in would be nice.

Armageddon, A low ENOB can indicate a noisy design.

[Armageddon]

Sorry Optikon, I change the post just now. I like the Rigol also. I'll look the Mixed signal version.

Optikon. What scope has mixed signal [MSO] with 16 channels of logic analyzer built in?
If it is the rigol DS1102D, it's the same dog (Voltcraft DSO1062D) with different collar.  

What do you think of MSO8102T? 700 € (ebay) http://www.owon.com.hk/MSO-en.asp#nogo
But finally buy the SDS8102 http://www.ebay.es/itm/290612117039

today I stumbled across a new local store that opened its doors couple of week ago. I found Hantek DSO-5202BM oscilloscope for $492, is this one OK to buy compared to the Uni-T I talked about couple of weeks ago?

I think the hantek series beats the uni-t hands down. The BM series has double the sample memory of the B series discussed here. I don't think the extra memory is very important, but it won't hurt. As it is already 200MHz, there is no case of a cheap upgrade from 60 or 100 MHz, but the $492 sounds ok (about 375 eur).  The hackable 60MHz B-model was 270 euros (VAT + shipping included) at the time, so the price for direct 200MHz + M is not too bad. For all the information be sure to check out the eevblog thread, it is only 100 pages.

to be honest with you, I don't like the way dave made people deviate towards Rigol DS1000E series. I will check that thread, cheers.

The thread is not dave at all. I don't think he even noticed hantek yet. The thread is created by a "crazy" German, who just desoldered all the components to be able to draw up the schematic. If you want to avoid the eevblog, he is active in some german language forums too. Not sure if that is your cup of tea. You'll find several contributions from me as well in the hantek thread on eevblog (under another name  ).

what's the nickname of that german guy?

Trust me Metal, forget Hantek DSO-5202BM. It comes to be the same as the Voltcraft DSOX062D and Rigol DS1000 series. In the end hardware does not convince me, and if I opted for the SDS8102 this has been for some reason.

[metal]

Which Owon software do you use with it? Also, your reason is deep memory plus 1Gs and?

[medik]

Having read this thread, I concluded that first i must have an oscilloscope to enhance my learning curve but local suppliers in Ghana don't sell scope meaning i have to order for one. I'm just a hobbyist and require something that can handle signals up to say 100KHz in case i need to learn how to build sine wave inverter and low cost, easy to handle by a newbie like me.  Any advice on this will be nice as i live in a remote area.

[sarah90]

It's tinhead. He started the topic.

The guy seems to be from Iran :- )

[Ichan]

Do I (We) need an oscilloscope? 

I am seeking for opinion, not to flame any.

Don't think he is entirely honest about that. Or he just moved. That's probably the case.
