Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China

<< < (146/258) > >>

Fungus:
Anybody have contacts at Rigol?

AFAIK they never gave any signs of reading EEVBLOG forums.

Yeah, think as tv84 and 2N3055 mentioned it's very early in the lifeline of this new HD DSO.

They did spend significant $ on the custom chip developments, so maybe Rigol decided to release early to save debugging $, and have early adopters help with the debug? This could be their business release plan for these new HD DSOs!!

We were very interested in the Channel & 12 bit ADC Linearity, this would be mostly for use with FFTs. Now raises the question in light of what we know, is linearity a factor for this HD DSO?? 

Anyway, it is what it is and has damped our initial enthusiasm some, being not as well polished as we had hoped.

Best,

... If you put scope in Auto memory mode, it will have high enough sample rate and you won't see this..

This is one of the problems, my scope was in AUTO memory mode, as i said I use most of the time auto setting, but maybe this is not a good habit. You should pay attention all the time at this parameter as it can change over a lower limit. The automatic memory management is not so reliable and in some cases, like this, it will not allocate the correct memory back to the necessary number.

In my opinion Auto mode is only way not to go mad in everyday work.  You go manual when you need.

I will exercise a bit more restrain before passing judgment and give them a bit more time to start releasing some FW updates.  When R&S released half baked RTB2000 years ago, everybody was full of understanding for almost a year, until R&S made it decent enough..

OTOH I knew it was too early to release it, and never had early adopter fever... But Rigol has a chance now to prove their mettle... or not. It's up to them.
