單台 U3606B 電源供應最大輸出 30 VA，它可以 30 V 1 A 或是 8 V 3 A，如果想要更高電壓或是更大電流，它也可以
串並聯，例如需要 60 V 1 A 時，可以兩台 U3606B 30 V 串聯，或是需要 6 V 5 A，也可以 6 V 2+3 A 並聯。截至目前為止，我還未見過以變頻技術設計電源系統的儀表，主要是電源變頻器非常容易產生雜訊干擾，只要有任何設計或製造不良，都會對信號測量或電源輸出產生影響，經過比較 U3606B 雜訊干擾程度與傳統電源系統的儀表相當，可見安捷倫這款電表設計技術卓越超群，堪稱史上最強的混合式電錶。
在輸出部分，這台儀表具有校正儀的品質等級，也就是說這台電表非常穩定，輸出信號也夠精準(四位半的解析度)，又能像電源供應器一樣輸出大電流，即使負載變動，皆可在快速調整回來 (0.1 ms 以內)，輸出有三種類型：定電壓源、定電流源、電壓方波(最高頻率 4.8 kHz)。
多功能電表方面，120000 數位顯示，DCV 0.025% 精度，可以測量交直流電壓、交直流電流、頻率、脈波寬度、方波工作週期、二線四線電阻、電容、二極體順向偏壓。網友 ijon 詢問太陽能板是否適合鬧鐘使用，就是用 CV 1.5 V 輸出 + DCI 10 mA 量測。
這台儀器我真的很喜歡，體積小重量輕，電錶與直流電源供應器二合一，很省電，牌告價新台幣五萬元有找。之前曾寫文介紹 U3606A 應用於測量 NXT 電力消耗，多年之後安捷倫再針對這款儀器功能、性能改良為 U3606B，裡面還有很多超值的功能等你挖掘，今天就此撰文推薦給電子電機方面的工程師參考。
最後附上官方對外發布 U3606B 的簡介：
The Agilent U3606B multimeter¦DC power supply offers the convenience of a 5½-digit DMM and a 30W dual-range power supply in an instrument with the same size as a 5 ½ digit DMM. This new U3606B replaces the existing U3606A with enhanced capabilities. The new U3606B adds new power ranges: 1V/3A with resolution of 0.1mV and 30V/100mA with resolution of 0.01mA. Power supply performance has been improved with ripple noise bandwidth increased from 1MHz to 20MHz, transient response time reduced to under 100µs and Voltage Programming Time enhanced to 50ms. The U3606B DMM 4 resistance wire measurement capability has been enhanced to include 1000Ω range.
The U3606B is targeted at basic instrument users in the general purpose market, including consumer electronics, semiconductor and communication. It provides convenience of most used 2 test instruments in a simple compact form factor, allowing a single GPIB or USB connection to control both of these instruments. With this two-in-one product, engineers, technician and students are able to handle most of the basic design validation requirements, powering up their DUT and measuring parameter via the DMM. Additional value features such as Over Voltage and Over Current Protection, Ramp & Scan functions, and Square Wave operations makes it even more convenient as it protects and offers faster means to scan devices parameters.
PS. 2014 年 8 月起，是德科技 (Keysight Technologies) 與安捷倫科技 (Agilent Technologies) 分家，這款電表現在隸屬是德科技的商品。

很棒，可惜還是買不起
回覆刪除請問，無輸出狀況下耗電約 17 W 是實測結果嗎？規格書似乎沒提到
ijon,
回覆刪除如果以個人財力購買確實很貴，但是以公司行號或學校單位的角度來看，二合一的電表可以節省開支，如果覺得好，可以推薦給工作單位採購。
17W 是實測的結果。
