Dear All,

I'm in a need of new scope and I have two contestants at the moment. Rigol DS2072A vs Rohde&Schwarz/Hameg HMO1002
Rigol looks on paper winner hands donwn. 2Gsa/s vs 1Gsa/s and 14Mpts vs 1Mpts. R&S is even more expensive than Rigol, but it is German design instead of Chinese Rigol.

Is there any reason to go over R&S instead of Rigol? I've seen the recent videos from eevblog where Dave tests scopes and is impressed with the R&S but it seems it was higher value HMO1202 instead of 1002 so perhaps same doesn't apply for 1002.. My budget is less than 1000$/1000€ so if there is some better option than these two please suggest. My use is hobby use so I know I could manage with cheaper scopes as well but I want bit better.

Your help is greatly appreciated.
 

Me too am looking for a 'scope.

I am thinking of buying from China because they offer good price. China manufacturing has come a long way- they are not at all bad.

My budget is still less but it seems I can afford one. Please tell us which one you decided...
 

there are really THREE things you need in a state of the art scope:
1) memory size
2) ADC bit number. i.e. avoid an 8 bit ADC front end, even if it seems fast enough.
3) as high a sample rate as possible
 
Some of the Rigol and other scopes come with protocol decoding either included or can be added for a good price. The R&S and more expensive brands normally come without any of it installed, and they cost a lot of money to unlock or add. It is all about your needs/budget now and later down the line.

You often find that you need a good analog and digital scope. I use a 200 MHz Agilent with all the protocols and digital channels but also frequently use a 400 MHz analog scope. Then we have a couple of older Lecroy boxes packed with power math/analysis functions, high sampling rate and deep memory.
 
Thanks for your input. What comes to the ADC bit I think anything above 8bit is way out of my budget.
Good point that protocol decoding thing. Rigol seems to have promotion that you get the decoding functions and more memory for free. Which make me think are they about to announce new products soon? If that's the case it might be worth to wait for a while. I might just pull the trigger for RS2027A even though it seems until now they haven't been able to publish bug free firmware for it.

Cost is exponentially related to the state of the art-ness of the scope.
