Here picture with Owon
(inside pictures also Rigol (from Galaxyrise pictures) and level adjusted for same size div's)
Owon input open. Capture mode peak. (so it use 1GSa/s data)
(owon screen size is 800x600, image resized)
Very similar! Did you have persistence enabled on the Owon? I'm guessing you did not, and that's why the Rigol line is more "blurry"
Very similar? Nearly 50% more is very similar?
No persistence on in Owon.
But persistence do not add detected peak values. Rigol images did not have mesurement on display so it can not see with numbers but still brightest part of Rigol trace is more fat than Owon.
It is not competition and difference is nearly marginal and I do not mean proof anything.... but I'm wondering Rigol advertisements where is
"...to deliver an extremely low noise floor to help you capture smaller signals." Can we now advertise Owon that it have very extremely low noise floor.
but Rigol advertised claims about special low noise is just ad without nothing more but just empty words. And this is "fun".
(we also know that Rigol front end is nearly copy from Owon, but perhaps from earlier Owon.. )
How can advertise low noise if there is 500uV/div what have around 1000uV noise. But building of the imagination is advertising professionals work. And it looks like Rigol is very good in this.
I have heard example total bullshits that Rigol DS1000E series signal capturing quality is better than Owon SDS. Of course these kind of opinions without facts are too easy to shoot down with raw data. Totally other question is who is listening becouse religions make it difficult. Very easy it happends that mind manipulating falses start live they own life. It is so easy to tell just like this cup is half of empty, but this cup is half of full, I take this last one.
It just so simple case that Owon have some marginal amount less noise. It is natural also technically becouse SDS7102 have some amount less ADC noise. Rigol (DS2000) is with 2GSa/s (2x1G) ADC and Owon use 1GSa/s (2x500M) ADC but also it looks like Rigol use RuiFeng ADC (what also Owon have used previously). (not big difference but part of decibel here and part there etc.. it makes finally some amount less noise. But also it is good to note that Owon BW -3dB point is over 170MHz. Also Owon discrete fet front end (previously dropped out one noisy and hot amplifier) have less noise than old precessor.
