Should I buy a Rigol MSO5000?

Great, that appears to be 12 MBits/second (2x 6,06 MHz) in comparison to the 480 MBits/second in the measurement i made on a CM6631A audio interface. You used cursors to determine the bit rate using two bit intervals, while i set a measurement gate to let the scope determine the frequency within that gate. And i could extract two different zooms, each one with its own gate and measurement.
It appears those scopes serve to derive the bit rates and the Rigol is good for full speed USB, while the Lecroy WR64Xi does USB2. This example is a bit silly anyway, since none of both scopes decodes the data. Don't know whether Lecroy offered this for the WR64Xi. We have a Lecroy SDA 6020 6 GHz scope that does it and puts the results into a table.

Risetime in your Rigol measurement seems to be about 80 nsec. Is this real or is that a bandwidth limit of the scope or the differential probe you are using? What is the input capacitance of that probe?

Regards, Dieter

PS: I guess it is real, because the differential logic amplitude is about 6 or 7 V, so it's an unterminated transmission line with the risetime determined by cable capacitance.
timber23:
The differential probe DP10013 has a rise time of 3.5ns and an impedance of 10M ohm/ 1pf.

The scopes rise/fall time is 750ps.

Following your argumentation, the cable is the reason for the slow slopes.

Best regards

There are many MSO5000 treads but this one has the title that asks my question!

Three years and several firmware updates later, and the Rigol is on sale now with the extra functions bundled so no need to hack if 100MHZ is enough.

Is this still a scope to consider?  Beaten hands-down by a newer rival?  Shipping with a brighter LCD?  Most bugs fixed?

Thanks in advance for any comments...

The answer is still the same: "What sort of things would you normally use it for?"

On paper thie MSO5000 exactly right for me - a cost effective mixed signal oscilloscope for a hobby use on small FPGA and embedded analogue/digital circuits.  Most of the discussion, and all of the online reviews, including EEV blog"s date from 2019.  I"d like to know

1. Have the firmware updates fixed the worst of the bugs which it was being criticised for?

2. Is it shipping with a better LCD these days?

3. Any new scope out in the last 3 years in the same price bracket that strongly rivals or supersedes it?
