Sniffing the Rigol's internal I2C bus
Mike_H:
A quick post to say thank you to all the hard work that this thread represents.
After 3 days of reading and play, I was able to enable the options I wanted on my new to me 2302A.
For the record my firmware is 3.05
Thanks again! :-+

Hi all,
who used J-Link (J-Link V8 ARM USB-JTAG) to download memory dump from MSO1074Z, tell me please pinouts connection. TCK, TMS, TDI, TDO it's clear. But where to connect TRST, VREF, SRST (what pins of J-Link)?
Thanks for any help!

I'm looking into the firmware for the past weeks or so to try and enable the 50ohm option on a non-A ds2k model with v2 hardware. I would except this to be a simple enough patch as long I could find the handling of the scpi "CHAN1:IMP FIFTY" command.
I'm just lost in those 8k of subs and simply fail to find the references to the "FIFTY" and "OMEG" strings. Could some one please point me in the right direction?
