owon: OWON two channel 100MHz Oscilloscope SDS1102: Brief review 2

I left my scope running non stop since yesterday, more than 12 hours now, sampling a ~20MHz ~90mVrms RF signal in FFT mode.

Nice and stable for such a low level signal considering this is a low cost scope.

 

And now injecting a RF signal at ~110MHz and the scope acquires it reading ~78mVrms, not bad for a 100MHz scope!

I can not test it above 110MHz because my old vintage Heathkit 1G-102S is it its maximum frequency now.

owon: OWON two channel 100MHz Oscilloscope SDS1102: Brief review

Recently I bought one of these OWON SDS1102 2-channel scopes.

1. Small intro.
Having worked in electronics since the 70's on several different fields from radioisotopes labs to telecommunications, I had my fair share of professional equipment from brands like Tektronix, HP,  RACAL, FLUKE, and so on, and it is easy to lose perspective of things when you are spoiled with 1GHz real time oscilloscopes in the 70's, some with storage memory.

2. Is this OWON SDS1102 a low cost scope, as advertised in their own website?
Yes, absolutely.
OWON is honest in what they are advertising.

3. Is it garbage?
Not at all.
For the asking price (I paid 190 EUR delivered from Spain on AliExpress) I can not ask better specifications and above all, real performance above what people may think.
It is an honest product, very useful when you need a dual trace scope with memory to do some basic repairs or adjustments on consumer electronics or even on professional equipment, why not.
The integrated counter and meters are spot on, I have checked it against my calibrated 520MHz vintage Fluke  1920A.

4. Is it badly designed and built?
Not at all.

If you are into electronics and have experience and knowledge on design and build equipment, you will recognize that this design is on pair with any other brand design on the same price  range.

Do not get fouled by the apparent simplicity when you remove the back cover and look to the three main assemblies.
This is a modern design, well laid out, properly shielded where required. It has nothing to do with lesser integrated designs that use bigger components and huge metal cans that give you a feeling of robustness, surely, but that has nothing to do with real performance of that product.

This is a complex design, miniaturized with SMD components on BOTH sides of the PCBs, and made as simple as possible without compromising the specs and performance.
In fact, it is impressive built considering the price point.

5. Are there compromises in design and implementation?
Sure, there are.
But you will find them in any other oscilloscope, irrespective of price range. You will want more. That is the human nature.

On this design, the analog vertical amplifiers and ADC could have 1mV/div instead of that 5mV/div with limited bandwidth, and the trigger could be more efficient to handle RF audio modulated signals.

On this implementation, the switching power supply could have been enclosed in a metal can. But again, why people, like myself, tell this? Did we actually took measurements on using shielded power supplies in this model? That is assumptions we made, without any proof.

Talking about power supply on this model, some reviews mention on how simple the power supply is, like a more complex design would be better. Again, that is an assumption without any proof.
The implemented power supply achieves the required specs with safe margin, and it is not as simple as people may think. The PCB has components on BOTH sides.
Additionally this SDS1102 model uses LOCAL Regulated power supplies close to the respective loads (look closer to the main PCB).

Do I like to see a huge electrolytic cap mounted over the main PCB in piggyback style, like they had second thoughts about the implementation?
No, I do not. But looking into other OWON models and PCB revisions, I understand that that decision is deliberated, probably to save precious PCB space and maintain the manufacturing costs in check.

The plastic injection used for the case components looks good to me, but it could be better. On my unit, the handle is warped a little on one side. Small thing, but enough to show where they cut costs.

6. Wrap up
That is all, folks.
This is my honest findings so far.
Others will have other opinions about this scope after they have used it for a while, I respect that.
