Sniffing the Rigol's internal I2C bus
Daruosha:
I ordered an Olimex USB-OCD-H. Let see does that work or not.
On things i was wondering could cause connection problem was the way i connected the pin hearders. Since i didn't want to fully disassemble the scope, i put 2 rows of 5pin so called "military" headers on the scope pcb and put an IDC cable and put rather heavy thing on the idc connector to keep the pin headers straight on the PCB. It sounds very stupid and rather idiotic, but i think the pin headers make a reasonable connection with pads. I couldn't find pres fit headers and i cannot think of any other solderless solution.
Any suggestions?
qwertymodo:
That could work, but I'd never trust it for something that takes this long. I've done exactly that for reprogramming micros, and sometimes it'll take 2-3 tries, which isn't a big deal when the whole thing takes 10 seconds, but do you really want it to come loose 40 minutes in and have to start all over?
Here are Samtec's press-fit series, you can get the exact 2x5 header you need: https://www.samtec.com/products/pht

My scope had firmware 4.03.SP2 installed, and I still had some time left on the feature trial licenses so I just halted the processor while the trial time remaining screen was showing and dumped the image.

Glad to hear that worked for somebody else. Looks like the timing of the dump really is (at least part of) the issue. Not sure what that means for people whose trials have expired. Maybe in that case, it might be possible to open the Options>Installed menu where it lists the trial options that have expired and try taking a dump while that dialog is displayed. psysc0rpi0n, maybe can you try that?

I didn't checked this thread for a few days... I'll try it right away!
Edited;
Ok, the generated keys were the same as the previous attempts so they were a no go! I halted the scope with the board of the installed option on the screen but no good!
Daruosha:
Let's assume I have the codes for 2000 minutes trial license keys. Can I uninstall them when it's close to expiration and re-install them (with SCPI commands of course)?
Is there anyway to completely factory reset the scope?

For those who have an interest in the DS4000, I have found the option codes for selecting the bandwidth .
This also sets the model type.
For example the code FAB9 will select 500Mhz, (DS405x), with all Decoders enabled.
The attached file contains all the details.
There are also two un-documented, possibly future, options called "Power Analysis" and "MA".
The option codes have been tested with firmware ver 00.02.00.00.04 and ver 00.02.01.00.03.
*EDIT*
Attached updated PDF document to include the option selection codes for LIN and 1553B decode.
Also included are two possible future options, Power Analysis and I2S decode.
Power Analysis has been listed for some time, but the I2S decode is relatively recent.
The original un-documented "MA" option has become the 1553B decode option.

Hello,
I successfully added decoders option to my MSO4024.
soft ver 00.02.03.00.03
hard ver 0.1.3.1
The 4-letter parameter to add decoders permanently: BAA9 (RS232, SPI, I2C, CAN, FlexRay, LIN decoders)
