I updated last night the firmware of my dso quad (HW 2.6) to the latest version from the wiki (sys_134,app_235,FPGA_25). I followed the manual and the response has been ok.
I used Win XP to do the update.
After that I tried to calibrate the DSO with an meter and a lap power supply for Ch A/B but this does not work anymore.
When I push the “Spop” button for 2 seconds the screen shows up for a moment and says “Parameters version error” and “exit without calibration”.
I tried the firmware update again but no change at all.
Would be someone so kind to give me a hint what I’m doing wrong?
I really appreciate any help.
Thanks a lot.
