content: I was looking for a handheld scope, specifically a used Fluke but the new Hantek handhelds look tempting, in particular the DSO1102B. Anyone have a opinion on usability/quality?Am I correct that they do not have a battery, but need a external DC supply? In that case I take it the leads are isolated?Thanks.

content: Huh? What use or How is a scope handheld if they are tethered to a plug pack?Of course it isn't. It's not well stated on hantek's website

content: 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 thatNow 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

content: Thanks for the detailed write up Achilles! It won't be my Lab scope, I've got one (or 3) already.The reason for the battery question, was I had assumed it had one, but after downloading and searching the 'Hantek DSO1000BUserManual.pdf" manual there is no reference to the keywords 'battery', 'charge' or any other term I could think relevant.The only thing I found in the manual was:Power SupplySwitching AdatperAC Input:100-240VACRMS,0.6A MAX,50Hz-60Hz; DC Output:9V,2ADC InputDC8.5-15V,2APower Consumption30W

content: Dear RRobot:--You can see Martin Lorton using the Hantek scope in video link below. Mr. Lorton is a bit more plodding and baritone than Dave, but meritorious nonetheless. He is a member here and is well regarded. I am a Fluke man myself, but I have not used either.--Also there is a rather nice Fluke Handheld at the below link. Probably worth a look, see picture.http://www.ebay.com/itm/TEKTRONIX-222-PORTABLE-HANDHELD-DIGITAL-STORAGE-OSCILLOSCOPE-/200829847238?pt=BI_Oscilloscopes&hash=item2ec26446c6"Does not squirrel crack nuts on bough of oak tree."Lao Fu 1410 1620Best RegardsClear Ether

content: Mine DSO1060 came with a battery, and it's OK. Word of wisdom: battery comes unplugged, so the first thing you do after getting it is to take off back cover and plug the battery."That's a trap for young players." (c)

content: Quote from: aluck on October 13, 2012, 02:12:04 pmYeah, but better than deep-cycling the battery through long storage periods in the shopsAh, as you spoke of isolated from the mains: Be a bit careful as the Hantek only handles up to ±20V on its BNC's. So keep that in mind when you setup your probe. I think most labscopes (you may be used to) are more tolerant here.As (maybe interesting) alternative there is also a new Siglent Handheld series released now (SHS800). These seem to be more compact and the built quality (external) looks nicer.The performance and functions seem to be more or less the same, but the Hantek is also available in 200MHz (SHS end at 100MHz)
