Sniffing the Rigol's internal I2C bus
Howardlong:
Yes, the scope should be on and booted. The dump process will freeze the scope though.
FWIW, the dump I had was on a Mac Mini 2012 Server running Windows 8.1 x64 which has its own problems, not least that as I remember I had to switch off enforced driver signing.
phersus:
Thank you Howardlong,
I got the same result in Windows and MAC OS X (at least the error is coherent :P )
This is the error message I'm getting:
phersus@MacBooKs-MBP:~$ openocd -d1 -f ./interface/olimex-arm-usb-ocd-h.cfg -f ./target/imx28.cfg

Any suggestion on what to try next ?

Re DSA815 with firmware 00.01.12.00.02: Can you please show us, or describe what the Full Scan (on initial boot-up, or after pressing the Preset button) looks like with the Scan set to to X = Log (for the Log. Frequency display). Thank you in advance.

Thank you 'mhwlng', we are both seeing the same results. I thought that this was Ok, and I feel better confirming it. The Rigol DSA815 also works well down to 9kHz as long as you set the Freq. Span., RBW, etc. for the appropriate Log. Freq. measurements. Thank you, Wall-E
