REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
<< < (415/566) > >>
Carrington:
I am really interested to know the new values (and also the others, C and R without marking code) of the input stage. 
And also I want to know where are connected the following points (Red circles).

So the rise time of the pulse is much slower than the rise time of the pulse from TEK Type 284 generator.  The measured rise time is 1.5 ns and over shoot only 3.5 % with old measuring input stage.

What exactly are you talking about or think Batronix/Rigol are talking about when referring to new and old measuring input stages respectively.

I'm pretty sure when Batronix wrote "new measuring input stages", they were not referring to HW 2, but just referring to DS2000 in general and that it was written when the old HW 1 was all there was known. IIRC this has been on their website for a long time: http://www.batronix.com/shop/oscilloscopes/Rigol-DS2072.html
So when they wrote "new measuring input stages" they were not comparing HW 2 to HW 1, but just comparing DS2000 to older Rigol series scopes, maybe like DS1000E series which might have a bigger overshoot.

Batronix haven't even updated their website yet to mention anything a bout DS2000A series scopes.

Yeap, that seems. Although I'm not 100% sure.

I just checked "The Way Back Machine" to make sure, and this info was on Batronix' website already on October 13, 2012, long before HW 2 came along. Source: http://web.archive.org/web/20121013114141/http://www.batronix.com/shop/oscilloscopes/Rigol-DS2072.html

Maybe so, I don't know. Here is however the same picture with text "lower over shoot" under DS2000A web page:
