Owon ADS804A oscilloscoop

Very interesting DSO from Owon. In fact in certain aspects it beats the DHO800 series from Rigol. Especially the FFT (though slower) is more accurate and has a slightly better dynamic range. Also the peak markers alongside the peak listing is better than DHO800.
Greyscale & Colormode works very good which really surprised me. This one is more aimed at the analogue guys versus digital guys. THe traces have a very fine resolution and noise is quite low. Mind you the input capacity of 20pF! OK for a 70MHz unit, but can be problematic if you go for the 100MHz or even 200MHz version. Same for the 900 series with 125MHz/250MHz. Even the biggest model of 900 series does not offer a true 50 Ohm termination unfortunately.
What really put me off (a question of choice and discovery) is that the analysis section is very poor to almost non existing. Forget about trying to record a data stream and analyze it frame by frame. Even it has segmented memory you cannot go frame by frame. It simply is not implemented. That makes it almost unsuable for any post analysis of data frames. That I consider a serious ommission and did not expect. Otherwise it is quite a capable acquisition system. It has a Windows trigger. Unfortunately it cannot display the pos. & neg. pulse side (you have to manually switch polarity) the same time! A Windows trigger is supposed to do that by all means, otherwise why set the pos. V and neg. V level the same time?
So, this one will unfortunately go back even though some aspects I really liked during testing. It depends what the user really wants. I see it more as an inexpensive analogue aimed tool and less an analyzing tool (for the on scope tools - post capture on PC is a different story of course). Quality of the unit feels quite good and it has a regulated fan, which is really nice plus a RTC!
