Hi,
I own a DSO QUAD v2.6 HW. I tried different versions of firmware but I now have problems locking the instrument and wrong measures (I ran the calibration). I want to reset the unit and reinstall the official firmware of the Forum, as in the table seeedstudio.com/wiki/index.p … mware_List.
I tried to put directly the firmware but problems remain, which is why I want to format / reset. Can you help me? 
Hi,
How is the measurement error?
Hi,
the real problem is that the DSO crashes, when you operate one of the menu buttons repeatedly. I found that concerns only the APP_B253, I reported to the B252 and the problem has disappeared. Unfortunately remain known issues inaccuracy of measurement frequency and amplitude.
Thank’s
