It is nice to see that Owon continue and highly focuses to develop HW. Signal quality is number one. Now it is even better than before although it was very good. (inside this price class) I'm satisfied they do not hurry hurry run to add many more features to user interface.

The World’s Most Powerful and Affordable Mid-Range Oscilloscope • 10G Sa/s Max Sample Rate • 500 Million points of deep memory • 600,000 wfms/s Waveform Capture rate • Search, Navigation, and Record utilities • Advanced Analysis Capabilities • 6 Instruments in one.

They focus to signal quality (first) In my opinion They have selected right road. Old rf-loop made table.

I have add new measured data. (marked with color) (measured with cursors, value is in () ) first value is oscilloscope automatic measured p-p value. Scope settings. Normal acquire, 1M sampling buffer, 50us/div Clear improvement! Look these 5 - 100mV/div values. (resolution is too rough for measurement higher V/div values.

(8 bit ADC and also display resolution) Also I can tell that front end run now markable cooler. (all tests are not yet ready, just started) -aghp Note: HW V2.6.2 it means equipment version (including FW) It is functionally same as 2.5.1. If look with user eyes.

(It is maybe different if look internal hardware interface) Also it looks very stable. Also this FFT tell something about noise level. (there is infinite persistence for show peak levels of noise floor. Scope settings 50mV/div (50 ohm Tektronix feed thru terminator in scope input of course) FFT zoom 10x and upper cursor is 0db (maximum signal level but of cousrse 100MHz is littlebit attenuated.) Signal level adjusted so that same level with 1MHz give just 10div p-p and with this level in signal gen frequency 100MHz (signal generator maximum error in flatness in this area is under +- 0.2dB) Then next picture. Signal level from generator dropped 60dB (in this case signal level is 172uV rms (-62.3dBm) Not bad result!

Well, some remarks. Firstly it's rather annoying for a customer when Owon releases one 'better' hardware after the other and customers of the now obsolete hw revisions feel like they're setting on a piece of outdated crap, wondering if they'll e.g. Ever get a firmware update again. Secondly this evolutionary development approach doesn't sound very professional. Usually you develop something first and then bring it to the market. Changing the hardware over and over again means nothing less than selling alpha and beta hardware to the customer in the first place. This might be an interesting financing model for Owon, but as said before, this is a bit frustrating for the customers who have an outdated hardware in no time.

Thirdly, it's not like the software was in a state where they should focus on the hardware. The hardware was always the best part about the Owons. So they should better invest a few Yuans in the SW finally before they scare away the last potential customer with the low end GUI, the lack of features and the crappy PC software. As long as you can't even measure a pulse in the 100µs range more exactly than 1µs at 1GS/s, who cares about improving their noise level a little bit more? Well, some remarks.

From start of SDS series all versions meet specifications. And yes, I know.

Some time ago I buy TV. New nice TV and all ok.

Next week I go other reason to same store. There was new TV. Lower price and BETTER and just same manufacturer (but slightly different model) In history I remember some TV. (yes tube) Some months before my friend buy good TV and later I buy same model, exactly. There was (1980) this evolution. My unit was different. First time it fails repaired and ok.

Metallicheskaya ferma chertezhi uzli avtokad. It fails later agen. (and agen and agen) My friend TV, no any fail.
