I have a DSO1202B:
-First of all....it has a battery. Otherwise it would be a bit useless
. I think there is a OWON Lab-Series that can be equipped with a battery. Maybe you have mistaken that
Now to the rest. All in all it works. I don't fine the case to be very well made but it didn't came apart yet. Doesn't feel as rugged as a fluke, but OK...for the price..
The Display gets scratched pretty easily. SO maybe buy some screen protectors and cut them to size if you plan to carry it a lot.
The battery runtime is fine (I think about 6hours), but it seems to me that it does use quite a lot of current when switched off. Even if the battery was nearly full, it drained a lot when unused for two weeks.
The Multimeter mode can't compete with a decent handheld multimeter. It is updating quite slow (about 2 readings/sec)
The big memory can come quite handy, but most times I use 4k or 40k, as it really slows down with 512k or 1M Memory (button reactions and the display looks a bit "rough") So mostly I use the deep memory for single aquisitions when I need it.
The CSV export seems to be limited to 40k max and the proprietary Hantek format (HWS....not the National Instrument Data Format
) seems only to be readable by the DSO itself, not the Hantek software. Workaround suggested by Hantek was "use the CSV".
The support wasn't the best I ever had in terms of speed and solution, but I also had worse....Hopefully I won't really need it one day....
All in all: It has its backdraws, but for the price works nice for me.
I needed a scope that could operate with a battery, is light and small compared to a Lab DSO (indeed the DSO1202B is bigger than I expected it to be) and shouldn't cost as much as a new car. So the Hantek fitted pretty much, but it is not a real substitute for a Lab-Scope.
If you need/want a portable scope it is quite handy (apart from the issues mentioned), but if you wan't a scope for use at home...maybe check out the lab-scopes
