If you like it, you like it but wait until you need advanced feature like protocol decoding to work. What baffles me is that people buy half baked products and pretend they are equivalent to equipment costing 5 to 10 times more. :palm: Rigol will need years to fix it. The threads about the DS1054Z, DS2000 and DS4000 series are all the proof you need. If Dave can spot several simple issues right of the bat then there are many more lurking because Dave's testing isn't thourough to begin with (and that is OK because really thourough testing would result in a long winded boring video). Edit: besides that: the Rigol MSO5000 isn't an entry level or cheap scope to begin with. They want a serious amount of money for it. |

The known issues from the latest release notes only lists two: https://scdn.rohde-schwarz.com/ur/pws/dl_downloads/dl_firmware/pdf_3/RTB2000_ReleaseNotes_v02.202.pdf --- End quote --- nctnico, I think his point was that I counted 55 bugs squashed after the first firmware. If anything, it was far from perfect when it was released and there were several basic issues. The remaining triggering bug is almost not even worth mentioning: it says it happens in "rare cases": how rare it may be debatable, but being on the other side of the fence (support and development) I can tell these types of issues may never be addressed due to resources being diverted towards more pressing bugs or features (or even entirely new platforms). As I mentioned before, any new platform needs time to mature, either from R&S or Rigol. What counts is the time to react. So far, the ball is in Rigol's court with the MSO5000 and the comparison could be R&S and their metric of 55 bugs fixed in two years (among new features). How many were fixed in the same timeframe on the DS1000Z platform? What about the DS2000? I can tell that, within 4~5 years after market introduction, the DS4000 reached the status of a very good and useable platform - not perfect, but all very important bugs were squashed. |

What counts most is the severity of the bugs. If a bug causes an entire feature not to work then it is much more problematic than missing a button press every now and then. Edit: And perhaps R&S isn't the best example. According to what I can find on the Google GW Instek announces the GDS2000E series beginning 2015. When I wrote my review (published februari 2016 https://www.eevblog.com/forum/testgear/gw-instek-gds2204e-(200mhz-4-channel-dso)-review/msg855862/#msg855862 ) they had a pretty much mature product and where able to fix the bugs I had found within weeks. |

Two (that I mentioned) are what they officially admit knowing about but didn't fix yet. One of those is from initial release 1.0.0 Other dozens are list of "improvements" (fixed bugs) On release it had more bugs than MSO5000. Just read release document. But they are R&S and they and they own their mistakes and fix them eventually. And everybody think it is Ok to be understanding towards them and their bugs are Ok. In two years (March 2021) we'll reconvene here and see if Rigol fixed their errors. That is fair, that is level field, that is not xenophobia, sinophobia or whatever crap is this smearing campaign here. If they didn't I will apologize to you and agree you were right. In meantime, you have nor right nor reason to categorically state "they will never fix it", unless you are clairvoyant and can see future.. |

I never said they'll never fix it. The fact however is that there seems to be a relation between sales and the frequency of firmware releases by Rigol for a product. The MSO5000 sits in a higher price bracket so they have to rely more on sales to businesses than hobbiests. If sales aren't what they are expecting then bug fixes will be slower or they might even abandon it. Time will tell but be honest: do you want to take that chance? Can you postpone buying a piece of equipment you need now by several years? Or put differently: do you want to buy a product which doesn't do what it is specified to do but you might find out when it is too late? There is a reason why I tested the crap out of the GDS2204E: I wanted to be sure it wouldn't throw me a nasty surprise at the worst possible moment like the Siglent SDS2000 did. |
