筆者的工作室有部安捷倫 (Agilent) 的直流電源供應器(DC Power Supply) E3632A,這是工作室比較貴重儀器之一,雖然購買時是二手,但價格也不是很平宜,原廠的價格更加高達 US$1281 (約港幣$9992),因為筆者是化不起購買全新的!但這儀器是非常穩定和容易操作,還很重 (9.5kg)。

安捷倫(Agilent)E3632A 直流電源供應器背面 |
這台安捷倫(Agilent)基本直流電源供應器型號是 E3632A 120W,單直流電壓雙範圍輸出
0 - 15 V,7 A 或 0 - 30 V,4A,具備低輸出漣波及雜訊,過壓(Overvoltage) 和過流保護(Overcurrent),還有 GPIB,RS-232 接口,廉容
SCPI (Standard Commands for Programmable Instruments) 指令,前面板的按鍵和操作是很容易,不需要太多和煩複的操作過程。
