Dear,
I need some clarifications about SDS7102 specifications -

In highest sensitivity mode (2mv/div) do I have to keep bandwidth limit on ? Or can I keep it off ?
and can I use 2mv/div on any probe atten setting (1x, 10x,..) ?

Is it possible to extract data from the scope in like for example WFM format ? If not what other alternative way can I extract the data ?

Sorry about very late answer. Perhaps you have find answer before my answer.

But this may be useful also for some other people.

2mV/div BW limit is always on and can npt shut off.

If you set probe swith to 1x and you set also scope probe setting for 1x then you can set V/div down to 2mV/div
If you set probe swith to 10x and you set also scope probe setting for 10x then you can set V/div down to 20mV/div

Scope menu probe setting just change numbers in V/div scale and nothing else.

It means that even if you select probe setting in scope menu forr 1000x and minimum is now 2V/div. If you set V/div to 2V/div and you connect 2mVp-p signal to scope input BNC then scope show just 1div signal. (but numbers in scope tell signal is 2Vp-p.)


You can save captured waveform example to USB stick.
There is now file header and after this sequantially every sample point in 2's complement binary. (one 8bit byte is one sample point)

If you read scope using Owon PC software (long time I have not tested this kind of things with Owon, so I can not quarantee today versions (scope version and PC softwre version) functionality exactly
Time when I have more tesdted these things have been 2012 and 2013.
With this disclaimer:

You can read scope waveform to PC. (PC-USB connection)
With Owon PC software you can convert this waveform raw data to .CSV format what is commonly used with many softwares, as also example with Matlab. Of course it can also use for many kind of selfmade or other third parties softwares.
