Thanks PA0PBZ!
I did not realise that also the bootloader file had to be renamed.  |O

The system information is now:

Software 00.01.09
FPGA 00.01.09
Hardware 01.01
Keyboard 06.01

Is the calibration still OK after the 1.09 upgrade?
If the calibration is back to defaults, your amplitude and offsets are way out.


I'm asking because if you upgrade the firmware on a DG1022, your calibration is lost, and loads factory defaults. I had this with my DG1022.

Just be aware that upgrading software on RIGOL generators it might loose your calibration!

If the calibration will be lost, I have lost it already two times before this update. This was third FW update for my DG4162. There is only manual calbration which is behind password.

http://bayfiles.net/file/1lrDi/0Wrw06/bfin_rigol_cybernet.rar (for IDA 6.1)

bfin module is (c) Andreas Schuler, rigol ldr contains some of my mods to also read GEL files right away.
PM me if u need the IDA DB with my initial reversing of the .GEN files.

maybe its worth checking new vs old bootloader to prevent rigol from preventing u to downgrade.
the old BL is fully reversed if somebody has questions about it.

unfortunately not much time for rigol stuff lately, but i see its in good hands ;-)

i would expect that ppl who can make use of my shared files are able to download them without infecting their computer with adware - if not, then i suppose it acts as a gatekeeper ;-)
