OK, to get the subject back to hacking. If I buy a MSO5074 (so I get 4 probes), I can currently take the Rigol offer for their bundle.
Once that's done, what are the steps to get extra bandwidth?
Is there any other feature you don't get from the free bundle?
Has anyone created a DIY LA harness?
Thanks in advance.
LOL Keysight...
yeap, I removed it now . It was on my clipboard . I searched for it .
I still don't understand how one may want to get rid of such scope and turn to a Rigol ....
sorry for offtopic .
Yeah, I read through that thread and thought it would be better to buy the Rigol original. Thanks.

There's a lot more to those adapters than just a few cables. I'm not saying they cost $300 to manufacture but making your own isn't for the faint-hearted.

Yeah but they were getting wrapped around the axles on detail like balanced pair routing and equal length tracks; it's a 350 MHz scope at which frequency the wavelength is 0.86 meters and the logic signals would probably not go over 100 MHz anyway.
I think a much simpler design with less exotic buffers and standard 0.05" ribbon cable would work just fine.

I'm going to permit myself this one off-topic digression and then suggest we shut up and keep the design discussion of an LA cable out of the hacking thread.
Routing
is an issue, but not because of delays or anything like that - it's down to managing current return paths. The kind of fast comparators you need for this task tend to splash a lot of current about and quite spiky current at that. If you don't manage your routes so that signal and return current keep physically close to each other with small loop areas you get into crosstalk and impulse noise issues. If you're packing 16 fast comparators into 2 sq in of board space you're going to have to spend significant time on getting your decoupling and return current paths properly sorted.
Read the probe thread carefully, apparently there is a lot of noise from the homemade probes, and the cost is not low, probably only 50% of the cost of the original one. And most of the published PCB files has mistakes on them.
The noise is internal to the oscilloscope, has nothing to do with the probe. If you enable the LA by shorting the pins on the connector, and don't connect anything to it, ghost signals will show up on the channels as they are unterminated internally. If you have any inputs connected (on DIY or retail probe), there are no ghost signals on those as the inputs are being actively driven. Rev 2 of the probe has the correct pinouts.
Can someone please do us new purchasers a favor and make a summary comment on the latest state of play with regards to hacking? I am ready to buy an MSO5074 but looking through the thread I'm confused as to the latest recommended best practice approach.
Thanks
[EDIT] Is post #933 still the latest to follow?

No, that's for firmware version 01.01.04.04 and the current version is 01.01.04.08.
Start reading forward from this post
Reply #1293 which contains the most recent reasonable summary of the manual version of the update.
Please note that if you're Unix/Linux competent you can make this manual process much easier to do by using 'scp' rather than shuffling appEntry back and forwards on a USB stick - basically get ssh access and then run the update entirely using ssh/scp.
I would suggest augmenting that procedure by checking the md5sum of both the pre and post patched appEntry to make sure that you've got it right. For reference:
md5sum of appEntry before patching | afe3e7c2d38bdebb66d3f1f11d910743 |
md5sum of appEntry after patching | 3f95cb3236b47826e303de960596f966 |
If you read later on you'll find mabi has posted a script to automate applying the same patch automatically from a USB stick. If using mabi's method be sure to save the
patch.txt file with Unix line endings, not DOS/Windows ones.
The instructions/attachments in
this message work for firmware 01.01.04.08.
Rigol had updated the V00.01.02.00.02 firmwire for MSO5000 few days ago. Does anyone use this latest version?

Yeah , but doesn't seem to worth loosing "upgrades".

[Supported Model] All the MSO5000 Series Digital Oscilloscopes
[Latest Revision Date] 2020/02/25
[Updated Contents]
--------------------
v00.01.02.00.02 2020/02/25
- Optimized the connection HDMI start problem optimized the connection HDMI start problem
- Optimize the vertical gear, channel zero elimination error
- Optimization of the inconsistency between SPI CLK and SDA names
- Zoom mode square wave display in optimized 2S time base
- Added command to get pass / fail times
- Delete the default email account and password
- Problems in remote instructions are optimized
- Optimized 1K storage depth, waveform recording
- The problem of too many stuck events in optimized decoding
So, I hope the experts in this topic would soon begin looking into this version of the firmware to see how the enhancement can be performed. Rigol has tried to make some of its AWG harder to "enhance" with the latest firmware, it would be interesting to see if they will do the same to the MSO5000.
mabl and tv84, would you kindly look into the feasibility of creating a patch file for this version of firmware, as well as whether there is any updated GEL file required to enable SSH?
The patch adaptation is a no-brainer that others can easily do. About the telnet .GEL, I think the one that is available can still work. If not I can look into it.
Thanks tv84, I appreciate it.
i didn't noticed before but wtf rigol, zip != rar
I afraid they are referring to the email feature documented in the manual, not the undocumented phone home feature. Who knows, they might actually have fixed the undocumented one
Any chance you can work on a new patch file for this version?
If we take it as a new major firmware version (upgrade from 01.01.xx.xx to 01.02.xx.xx), it seems that Rigol have no intention to add some new useful features (like Bode Plot, a better hi-res implementation, etc).
I suppose in the future there will be only incremental improvements for bugs.
Still, MSO5000 is a funny brute force beast. And hackable

No, they are referring to the default username and password that I used to log into their IBM Notes system because :woops: it wasn't just a placeholder.
