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

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 . --- End quote --- I can't replicate this particular error on my Rigol, so I'm not sure what is causing it. --- Quote ---Fuzzy Traces --- End quote --- 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. --- Quote ---It looks like Min. Presistence is set to an incorrect value!!! and is about 200ms --- End quote --- 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). |

That seems like a pretty specific bug ;D --- End quote --- 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 |
