Sniffing the Rigol's internal I2C bus

I have followed the tutorial on a MSO2072A it works perfectly. ;D My firmware is 3.03.sp1.
Thanks a lot for that ! That's a really nice work.

For curiosity, I want to understand the details of these hacks, but this thread is huge. I've already read the first 40 pages and want to summarize only the technical details without all the chatter. Or just extract the relevant threads. Is there anyone else who want's to join me?

Does Rigol have an average/typical release cadence for new/replacement products?

--- End quote ---
The DS2000 is still one of their newer series. I'd be very surprised to see a replacement line before 2018 or so.

That's not to say there might not be a model introduced with some minor tweaks (like the change for DS2000 to DS2000A, which added the 50 ohm input, or the -S version with the AWG added - at extra cost).

But the DS2000 series is still extremely competitive, I'd expect Rigol to be working on other things - for example their DMMs are getting old (much older than the DS2000). Compare to the latest Siglent and Agilent...

for my DS4024 I see options for enabling decoders.  However, are there known ways to increase BW? 

don't see discussion of that in the thread (I didn't read all 262 posts tho) and gotroot only shows non BW related option enablement.

will DSH9 "all options" also bump bandwidth? to what?

This worked for me: https://www.eevblog.com/forum/testgear/sniffing-the-rigol%27s-internal-i2c-bus/msg633003/#msg633003

I have an MSO2072A with firmware version 00.03.00 SP1 and hardware version 2.2.

I tried the USB port but it wouldn't work so I tried the LAN connection and that did the trick.  :)
When sending the commands using RigolBildschirmkopie.exe it said "There was an error when sending the SCPI command." but it worked anyway.
Looking at the installed options, it says I have both the 200MHz and the 300MHz options installed, along with all of the rest of the options.
