DSO 112 DIY kit

Introduction

DSO112 is a pocket oscilloscope with color display and touch panel. What makes DSO112 distinguished among peers is its easy opertions, which are all straightforward touching and scrolling. Almost everything is self-teaching. You would not get lost as you might do with other handheld scopes. Designed specifically for students and hobbyists DSO112 is a great entrance level oscilloscope. With a size that fits right in your palm and pocket DSO112 can do much more than you might think from its dimension. High sensitivity (5mV/Div), high accuracy, and low noises are highlights of DSO112 and make it a useful tool for small signals probing. 2.4 inch TFT color LCD (320 x 240 in resolution), 1200mAh Li-ion battery (optional), and built-in smart charger... all these add great convenience in use.
