DSO NANO v3 是一個 32 bit 的數位儲存示波器。基於 ARM Cortex™-M3,具備 320x240 全彩 TFT LCD、內建 2MB Flash、USB 連接、以及信號發生器等功能。結構緊致,操作簡單:滿足了學校實驗、家電維修、以及電子工程的基本需求。DSO Nano v3 與 v2 最大的差異在於將白色塑膠殼替換成黑色的金屬外殼,更為堅固耐用。
請注意這個裝置具備兩個端子。一個是從探針的波型輸入,另一個則是訊號產生器的輸出,詳見 http://www.seeedstudio.com/forum/viewtopic.php?f=12&t=2240

DSO Nano v3 是業餘玩家級的 DSO,除了輕巧的體積之外,最大的好處莫過於可以讓使用者自行撰寫或更新韌體。除了可以擴充功能以符合自己需求之外,並且可以從中學習到一個完整的嵌入式系統設計,這種額外的價值,也算能夠補足產品功能與規格不族的缺陷。先列舉其中之一如下。
想要更換成玩家版本的 firmware,詳見 The DSO Nano v2 Pocket Oscilloscope Explained 有非常詳細的說明。
根據網路資訊顯示,DSO Nano v3 受限於硬體設計,主要是可以用來測量 200 KHz 範圍內的類比訊號,如音頻訊號或某些 PWM 測量等需求。如有更高範圍的需求,請參考 DSO Quad 或其他專業儀器測量廠商之產品。
