What happened to the nice handle on Rigol oscilloscopes?

[pascal_sweden]

The current oscilloscopes from Rigol don't have the nice handle anymore like the older Rigol models used to have.

Example: Rigol DS5202CA



I think that the handle on the Rigol DS5202CA looked really nice and was very robust.

The newer oscilloscope models are not that deep anymore, and that's why they could actually replace the handle with plastic feet on the bottom. Still I believe that the handle was looking much better!

Interesting to note actually that the function generators, digital multimeters and RF signal generators from Rigol still have this nice handle today.

When is Rigol going to launch a retro edition again of their oscilloscope?

Is there anybody out there who has a Rigol DS5202CA? That oscilloscope could be a nice collector's item! =)
If so, can you make a nice review video about it on YouTube?

These older Rigol DS5000 models ending with (E) also supported Equivalent sampling up to 50 GSa/s.

From the Rigol DS5000 User's Guide: "Equivalent sampling: Known as Repetitive sampling. In this mode, you can get up to 20 ps of horizontal resolution (equivalent 50 Gsa/s). This mode is good for observing repetitive signals, and it will not be available for single-shot or pulse."

Why do newer scopes no longer support Equivalent sampling? Does anybody know?

Note that the first oscilloscopes from Siglent also had this nice handle.

Example: Siglent/Atten ADS7202CA

Probably because newer scopes are not heavy at all.
Also, that kind of handle will use some extra space on your desk.

The newer Rigol scopes have a nice handle that folds down flush with the top of the scope, and easily pops out if you want to carry the scope like a briefcase. As far as I'm concerned, the new handles are far superior -- allow a denser layout of equipment on my shelf, never get in the way, and fulfill every requirement of a handle.

Any feedback on this question?

Yes, I read about your comment regarding ETS mode on the DS6000 earlier today.

That's actually why I brought up the question here on the older DS5000 series

Rigol used to have several "E" models in their DS5000 series.
They had several models without "E", and several models with "E".
So it should have worked there properly at least, back then.

Maybe it is more difficult to do now with the newer ADC chip and dual FPGA architecture?
Wonder what ADC chip and FPGA architecture that they were using back then.

Is Rigol actively working on this for the DS6000 series? Would this affect many customers?
Can you provide specific examples and application areas for ETS on a scope that already has 5 GSa/s?
What is the maximum potential sample rate in ETS mode on the DS6000 series for a repetitive signal?
(I mean, under the assumption that it actually would be working on the DS6000 series)

Do you know more details about the ADC chip and the dual FPGA architecture in the DS6000 series?
Are they still using an 8 bit ADC in this high-end scope? Or is this 10 bit or 12 bit?

[pascal_sweden]

Do you really need such a high sample rate (200 GSa/s)?

If not, you can try to find the older Rigol DS5202CAE model, where ETS mode works perfectly fine!

From the Rigol DS5000 User's Guide: "Equivalent sampling: Known as Repetitive sampling. In this mode, you can get up to 20 ps of horizontal resolution (equivalent 50 Gsa/s). This mode is good for observing repetitive signals, and it will not be available for single-shot or pulse."

Maybe Rigol still has some NOS models of the Rigol DS5202CAE scope in stock.



You can check with your Rigol contact in China, and if they do, let me know.
I like to get one as well, if it is NOS =)
