he said he was browsing around and asked me today about hantek (on aliexpress) any thoughts from anyone here on those i notice in reading some hate them and some seem to like them. just curious.
DSO2C10, DSO2C15, DSO2D10, DSO2D15: a relatively new model. people seem to have various problems with firmware bugs, and they seem to be designed and built to a
very low price point. i'd personally not recommend them unless your budget is very constrained, and advise to keep your expectations quite low. having said that, they are better than no scope!
there is also Hantek's DSO5072P that he may have seen and has been around for quite a number of years. relatively small memory depth (40kpts i think) and they seem to have a propensity to occasionally blow up their power supply or corrupt internal firmware. again, only consider if your budget is constrained and keep your expectations low.
as for AliExpress: don't touch with a barge-pole! you will have next to no backup if anything goes wrong such as a warranty claim. i buy quite a bit from Ebay (china), and
occasionally from AliExpress, but
only small items where i am happy to write off the purchase if the purchase turns out to be a dud. small components and electronic modules, nothing costing more than a few dollars.
my scope recommendation would be to go for Siglent, their models are a generation newer than Rigol's DS1054z et al. OR, if he can find a cheap/small transistorized CRO built post-1980 for us$30 or less, get that as a stopgap until he decides upon a DSO. a CRO is still usable for many things, but as others have said a DSO can do a whole lot more.
all 100% opinion, of course!
cheers,
rob :-)
