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

<< < (374/566) > >>

Fix the print screen problem:
The Ultra Sigma will not take a screenshot with the DS2302 if we upgraded. The reason is that the Ultra Sigma could not recognize the DS2302 during the hand shaking process.

I found out a way to fix this, there is an Init file(file name "Init") under \RIGOL Technologies, Inc\Ultra Sigma, Open it and locate to
[PrintScreenSCPI]
......
DS4012D = ":DISPlay:DATA?"
DS2072 = ":DISPlay:DATA?"
DS2102 = ":DISPlay:DATA?"
DS2202 = ":DISPlay:DATA?"

Add following line below the DS2202
DS2302 = ":DISPlay:DATA?"

Save the file

That is all.

Ok - after these latest tests, I'm happier with the newest firmware from Rigol.  ;D

Rigol has improved the waveform update rates at many of the lower time base settings, with the following results:

The DSO is now able to achieve close to 50k wfrm/s (Dots mode) @ 3 different time base settings: 1ns, 5ns, & 20ns - and @ 2 of those (1ns & 5ns) using vectors.
At the other 3 lowest time base settings (2ns, 10ns, & 50ns), the DSO is faster with both channels ON (Dots mode).
With any setting (1 or 2 channels, dots or vectors) @ <= 10ns/div, the wfrm/s rate is >= ~24k.

The one detrimental (and rather oddball) change is single channel, vectors @ 20ns/div (and yes, I checked it several times): it has dropped considerably from it's previous rate (making 5ns the fastest rate for a single channel using vectors). But considering the improvements in the other rates, I can accept it.



The old wfrm/s charts in the first post will have to be updated, so I've removed the old ones for now.

Bugware:
I love it! That are good news and impressive improvements! Thank you for your work!

NikWing:
and that's not a new bug?
dropping from 47k to 17k while nearly all other values got better?

Carrington:
This is strange:
