REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
<< < (231/566) > >>
Leon:
I've ordered a 2102, it should arrive pretty soon.
devitrify:
I recently received our DS2102 scope -- it's my first digital scope, and it's a huge step forward over my old circa 1980 HP!

We plan to use it for our high school robotics team.  I hope to use the decoding functions for our CAN bus, and I am pleased to see some great demos of this capability already posted.

I've run into a few bugs, and have contacted Rigol who says they are known but that there is no firmware update released yet.  You can see in the attached image, a bug where all the test data is wrongly shown as identical.

My DS2102 scope shipped in May 2013 with:
   Firmware:00.01.00.00.03
as reported in the file NewFile1.txt that I downloaded onto a USB flashdrive.

Though maybe not a bug, I noted that when I download a waveform onto a USB drive, the resolution is reduced below that displayed on the scope.  For example, at 2 V/div, the resolution in the downloaded file is 0.080V.  For a full screen deflection of 16V (= 8 x 2V/div ), the # of steps is 200  ( =16V / 0.080V).  I'll have to explore more to see if it is possible to download at higher resolutions.

In spite of the bugs, my first impressions of this scope are very positive!

Hydrawerk:
Those Rigols are feature rich, they have good hardware, but because of those bugs
 :palm: :palm: I would never trust this scope.   :-- Anyway, when they finally make a good firmware without bugs, it will be a good scope.

This bug was just introduced in the last version of the FW - and has already been fixed in the upcoming version. It is in our bug list on the opening page:
Re-selecting two or more measurements from the left-side menu after booting-up can cause some of the measurements to be incorrect.
Current workarounds include:
Only select one measurement for screen bottom
or - use 'Display All' (with 0 or only 1 measurement at screen bottom)
or - make sure System -> Startup is set to 'Last', then select the measurements you want at screen bottom and reboot.

I'm not sure exactly what you mean? What file format are you talking about? WFM? CSV? TRC?

I'm not sure what benefit you think these kinds of comments are bringing to this thread, but in any case you're wrong. There are very few bugs in the FW (and certainly nothing serious) - it's completely trustworthy - haven't you noticed that Dave uses it all the time in his videos? And the DS2000 is unquestionably both a more powerful DSO, and a much better deal, than the Agilent DSOX2000.
