Peleus 寫:這個也是左邊產品的樣子,是嗎?
我先前也有看到老外用它,不知好用嗎?
locky-z蠻多老外說會壞掉的,所以應該是不會考慮吧!
一直想找看看有沒有日本仔出的這種東西,看會不會設計好一點?
這是"Peak Electronic Design"的產品,看公司網域應該是在UK,[更正]他在中國沒有設廠,不過有中國廠商取了個名字叫"Peak Electronics"
(更新)他官網上有聲明

Additionally, all our manufacturing processes are performed here in the UK so we can keep a close eye on all the steps from design, through manufacturing, calibration, testing and packing.

他偵測後自動設定測試條件的功能蠻方便的,
然後我發現這顆跟ATMega328 LCR meter測出來的hfe會有些差異
比如說我在mouser買100顆BC546回來用ATMega328 測出的hfe會有28X-29X/32X-33X/42X-430X這樣的分布
然後用DCA75這顆測起來全部都在280-290左右,曲線跑出來也是這樣,沒看到超過300以上的
老外跟我說以DCA75測出來的為準,我也就暫時這樣用。
然後一些在露天跟EBAY買的2SK170,用ATMega328 測試會判定成NJfet的,用DCA75會判定為BJT或ZENER
(如果用ATMega328都判定成BJT的,用DCA75都是判定成ZENER)
相對的也有以前跟AMB買的2SK170用ATMega328 會判成BJT,用DCA75會辨識為NJfet
至於現在看得到的缺點...是我怕裡面的電池會漏液跟那三條尾巴被扯斷吧...
DIYAUDIO上的一個
locky-z串有提到有日本人用Analog Discovery 2弄了個測試介面
在第一頁最下面,然後第二頁也有個網站在賣類似的東西
含AD2本體在內大概入手成本8000-10000左右
