Having you looked at the cost of options for what they compared their scope to? This isn't a replacement 1054Z.

I understand what you are saying that its not a 1054Z replacement and compared to A brands its price is competitive.The thing is that its new and untested, and has not been independently assessed by any qualified 3rd party yet. New ASIC feature set and specs remain simply advertising blurb until tested live in the lab.

Rigol are good cheap test instruments that generally if buggy when released get fixed, but the DS-7000 as I said before does not tempt me. Cheap to get into then expensive to option up. Rigol need to add value for the prospective customer to consider this scope over others.

To make this value brand scope sell then Rigol will need to sharpen their pencil and add real value for the user. IMO Rigol need to offer all protocol decoder options free on all the DS-7000 models. The cheapest 100MHz BW model as well as having the decoder options free, should also start at 200MHz and drop the 100MHz model option altogether.

Rigol need to understand that their market share comes from the value for money sector of test equipment. When spending $11000 on a value brand like Rigol DS-7000 the other 'A' brand DSOs will win me and my money.

I would love to buy a feature rich DSO like the DS-7000 but Rigol need to be more realistic in their pricing. Option enabling on the scope is value adding for Rigol only, (increased profit) and not the customer who can clearly see hardware is already in place.

It would take a massive pricing rethink by Rigol to tempt me to buy their new scope. I would love to upgrade to the new Rigol instrument, problem is its priced like a Porsche and in reality its brand is the analogue of a Great Wall pickup.

When are we going to see independent reviews on this new Rigol scope?

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.
jjoonathan:
Seconded. Rigol's 4000 series had a bug where serial decoding didn't work in segmented memory mode until years after release ::) , it would be good to know if there were any similar bugs in the 7000.

The 4000s also have annoying trigger UX, but AFAIK that's a result of the firmware and software, not the hardware. The hardware trigger works OK -- no sub-sample spacing but otherwise fine, and no clock jitter on trig out, so it's a real trigger rather than a GPIO abomination. The jankiness comes from the fact that its time offset isn't calibrated out in the FPGA so the software attempts a secondary digital trigger to nudge the trigger crossing a few ns to the specified trigger location. This works fine when the trigger is on-screen and not at all when it isn't. Also, for some reason, the software trigger isn't applied while scrolling, so on low ns/div the signal appears to hop between the uncalibrated hardware trigger and exact software trigger, which is frustrating. You can work around this problem by manually entering a timebase offset to calibrate out the trigger delay, but ugh.

Dave! if your reading this?
Have Rigol made this new scope series available for test and tear down anytime soon with you?
pascal_sweden:
Yes, we are all waiting for this detailed review as per above description! :)
