I have just bought a DSO nano 201 with a pcb V1.5C_MB with a welcome screen that indictates (presumably firmware) version 1.4.00p
The case style is black plastic with a joystick up/down/left/right keypad.
My first impression of the unit is that it looks reasonably well made but that it is let down by the display variables and menus being a crude translation into English with many mistakes.
I would like to upgrade the unit firmware to see if a later version at least removes these errors before I start to learn how to operate the unit.
What is the latest version of firmware I can load on this unit?
