New Rigol DS7000
pascal_sweden:
The actual review should be detailed and not be fluffy!
--- Quote from: pascal_sweden on July 04, 2018, 03:04:57 pm ---When is Dave Jones going to review the MSO version of the new Rigol 7000 series?
In this review I would like to see an extensive real world protocol decoder test and Logic Analyzer test.
The test should test the speed when using full memory depth, and should verify if the protocol decoding is really done in hardware.
One should also make a long memory capture, and search in the long memory capture to verify how easy it is to search within a long trace.
Maybe use an actual PCB board of a commercial product, where I2C, SPI, CAN signals are present, and perform a real world protocol decoder test and Logic Analyzer test.
Perform a real world troubleshooting session, to put the product to a real world test!
This video would have a dual function: verify how good the MSO version of the new Rigol 7000 series is, and at the same time educate about troubleshooting techniques using powerful protocol decoder and LA tools.
Of course the test should also verify how good the new analog front-end is (bandwidth, trigger implementation, jitter, noise level).
Rumours in the past indicated that Rigol engineers have no clue on how to properly implement the trigger circuitry, and that there actually is a fundamental flaw in the design.
Maybe the trigger implementation can be verified in the new Rigol 7000 series.
Another nice test would be to check if Rigol has a similar feature as Siglent to generate Bode diagrams on the oscilloscope, where the oscilloscope controls an external signal generator.

Such a thourough review takes a lot of time (I've been down that road before a couple of times) and doesn't lend itself well for video. I think Dave will take it apart and do a quick tour on how it works in general (and that's probably it). The teardown will be kinda interesting but not something you'd use for a purchase decission.

Emona Instruments clearly state they will be making the DS7000 available to Dave for a review. There is a clear expectation that Dave will review the product and I'm sure he will also do a teardown while he is at it!
pascal_sweden:
Such a great and marvelous piece of equipment deserves a great and marvelous review!

Since Dave did the quick teardown of the Siglent 1104X-E 8 months ago he has not seriously revisited this scope. I know when he did the Rigol 1054Z it was a market changing release and he did a couple (2 plus a dedicated summary) indepth reviews of it. Since I am in the market for a low budget 4 channel scope I am disappointed at not seeing a more serious follow up of the Siglent. I know Dave is more of a hardware guy than software, and most of the changes to the Siglent have been soft/firmware. I am quite interested in seeing how he treats this Rigol 7000D, in what seems a fairly substantial release from them. Will he give it the indepth 2-3 video attention he gave the 1054Z? Is he getting away from dissecting equipment that deeply? I know there have been a good number of other YouTube reviews of the Siglent 1104, but Dave has been kind of the standard I use to judge the others by. Even though this scope is way out of my market, it's design and components may trickle down to the hobby level I am at.
