REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
Teneyes:
There also looks like an Error on the other end of the Persistence settings, It looks like there are different processing for these two settings
Below I show settings of 20 seconds and Infinite Persistence

It would nice to be able to turn off SinX/X .

I can't replicate this particular error on my Rigol, so I'm not sure what is causing it.

The Siglent changes the grading a bit when when turning on more channels, but not nearly as much as the Rigol. In fact, the intensity grading on the Siglent is really quite beautiful - much better, in general, than the Rigol. I'm going to make an extra short video just about the intensity grading and post it in the next couple of days.

and is about 200ms

Min. persistence is zero persistence - just intensity grading. And even though both intensity grading and persistence produce the same visual effect of shades of color, they are calculated and graded differently (although I don't know exactly how Rigol is doing it).

to Clarify , the setup is :
FW 00.03.00.01.03
300MHz options, all Options installed??
mostly observed on 5nsec/div
70 MHz input
2 channels On
Memory Depth = 28MPts, , AUto sets to 700 Pts and Blurs traces
Single scan to show ripple (less ripples with only 1 chan on)
DIsplays with DOts and Vectors at Infinite Persiostence

It has to be a 70MHz input @5ns/div? That seems like a pretty specific bug ;D

Well ;D, It shows on the peaks of 30-120 Mhz, and more at 5ns/div.
I say it is a quirk of the SinX/X implementation
I un-installed all Options an only added 56MPts back
Here are Gifs. , of Vectors and Dots Recording with 50MHz input ON FW00.03
Note how the dots are follow on the sin curve but in VECTORS there is a rolling ripple of 1 GHz !! :-//
The next Post will be on FW 00.01
