REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol

<< < (362/566) > >>

marmad:
I have to say: so far I'm rather disappointed with Rigol's latest firmware release (after waiting 6 months).

I haven't seen any new features added (most disappointedly: no change to the lame External Trigger) -  although I have found at least one minor bug fix so far (see next post) - and perhaps more to come with further tests.

So far, the only UI thing I've noticed that's different is the way they display the Options Installed table - slightly smaller and more condensed (room for more entries):

It seems Rigol has definitely done some work on the intensity-grading in the Zoom window of Delayed Sweep in the latest FW release. It was often too light - much lighter than when just stopping the DSO and zooming in by shortening the time base - which forced you to crank up the intensity all the way some times.

Here is a screen image I made documenting part of the problem for them (via Drieg) back in June using FW 01.01.00.02 - with the intensity setting around 30%:




Here are the exact same signals and settings (including 30% intensity setting) using the latest FW 02.01.00.03:

Marmad,

The intensity grading looks much better in the new DS1104 scope. I am presently evaluating both DS2202 and the DS1104Z side by side along with my agilent DSX3000. The best intensity grading is won by the Agilent with the DS1104 a close second and the DS2000 last. That was one of my complains in evaluating the DS4000 series in that the display was in certain conditions too dim.

Ooo, did they fix high res in roll mode? It had the same problem.

This would be a purely subjective opinion - it sounds like you prefer intensity-grading with a narrower band. Both the Agilent and the DS1000Z have <=64 levels, while the DS2000/4000 have up to 256 levels.

I like the intensity-grading on the DS2000 fine - more than what I've seen in videos for the Agilent X-Series and DS1000Z. The main problem, IMO, was the implementation of it when in Delayed Sweep mode - and it appears that Rigol might have finally corrected that issue.
