PDA 也能變示波器

只是不知道 如何輸入信號 ??
--> 好像使用 Microphone 當輸入 http://www.virtins.com/

還有一堆其他軟體 ,
如果 可以使用 pda 當隨身 示波器
量東西就方便多了 只是輸入頻率應該不高吧 ..

不知道 將來會不會連 circuit simulation 軟體也有 PPC版本

9. Can be used as a transient signal recorder to capture and store data for up to 500s.

10. Four view types: Real time wave form display of Channel A and Channel B, Real time wave form display of Channel A + Channel B, Real time wave form display of Channel A - Channel B, Real time Lissajous Pattern display for Channel A and Channel B

11. Independent X axis and Y axis zooming and scrolling

12. WAV file can be imported for display and analysis
