Experience with China Oscilloscopes?

(1/3) > >>

fchk:
Hi,

I'm thinking of buying a new Oscilloscope. I've got a Tektronix TDS220 now, but would like to upgrade on these reasons:
- 4 Channels
- more memory
- better screen

My options are:
- buying something better from Tektronix, LeCroy, Agilent,... used (I'd like to spend 5k, but I simply can't)
- go for some China equipment new

When I buy an TDS3014 or an TDS764, well, I can assume that there are certainly no serious design or software bugs in it and the only risks are worn-out crts or leaked capacitors. But I'm very unsure what to expect from Rigol or Uni-T or Owon etc etc.

Greetings from Germany
and sorry for the 4:0

Dave has an extensive review of the Rigol DS1052E.  You might know what to expect after checking that out.

squeezee:
The annoying thing about these chinese manufacturers is that while their 2-channel, entry level scopes offer very long memory depths; None of their more expensive ones do! (although compared to the tiny memory in the TDS220 anything will be an upgrade)

Exactly how much are you willing to spend? and i assume you're looking at something with the same 100MHz bandwidth?

saturation:
Chinese oscilloscopes are a hot item on this forum.  Dave's Alexa ranking has been growing steadily, and Rigol and the 1052E are top search terms that lead folks here.

On reading Dave's original queries about the Rigol in 2009 elsewhere on the 'net [ where discussant dissect other Chinese scopes like Atten, Owon etc.,]  one scope that was left out but seems to perform very well, and has a company with a stellar reputation, is Instek.  Given a 4 channel scope has not yet been reviewed here, AFAIK, I'd like to hear what anyone has to say about Instek scopes and particularly its 4 channel models.

Face value, the Instek 1062 is a direct competitor to the eevblog popular Rigol 1052E, but most talk is about getting a low cost 100Mhz scope by hacking it, than examining all its functions as a general purpose scope.

Hacking aside and all things equal thereafter, the Instek offer better value with an upfront cost difference of $16.

I'm prepared to spend 2k Euros.
