DSO Shell has similar bandwidth as DSO138 but contains significant improvements in structure, mechanical, and operation.
Display and MCU are now mounted on the same board (mainboard) to avoid using inter-board pin-headers
Main board can be used as a flexible general purpose controller
Comes with full enclosure. The front panel and top/bottom brackets are flexable for easy user modifications
Rotary encoder has been added which makes parameter adjustment much quicker and easier
Sensitivity has been extended in both directions and is higher and wider than DSO138, reaching 5mV/div - 20V/div
