Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the ProtectIOn limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level.

Proprietary Code Read Out ProtectIOn (PCROP) ----- 專有代碼讀取保護 現在產品開發過程中，二次開發將會越來越多，設計公司開發出自己產品后交給終端客戶進行二次功能或補充開發，簡稱二次開發，設計公司某些程序代碼不希望公開給終端客戶，但同時又希望部分函 數功能可以給終端客戶使用，這時就需要有一種專有代碼保護機制供客戶使用，STM32F4xx 芯片中的 PCROP 可以解決類似問題。

PCROP 為Proprietary code readout ProtectIOn 的縮寫，也就是說這是一個專有代碼讀出保護的功能。與RDP 對整片Flash讀保護不同的是，它只是針對Flash 的某些特定區域進行代碼的讀寫保護。所以它可以被用來保護一些IP 代碼，方便進行二次開發。它存在于許多STM32 的型號中，如STM32F401、STM32F411、STM32F427/437、STM32F429/439、STM32F446、STM32F469/479，STM32L476/486，等等。對于PCR

為適應雙向DC/DC功率變換的電流采樣需求,一種高精度高邊電流采樣電路被提出。其基本思想是在功率電路的高邊串入采樣電阻,借助電流鏡原理并引入偏置電流電路,將雙向電流均轉換為正向電壓輸出。通過理論分析與仿真結合的方法對電流鏡采樣原理及4種不同的偏置電流電路方案進行對比,最后通過實驗數據驗證了高精度高邊電流采樣電路的有效性。實驗數據表明,該采樣電路可在-25~75℃的溫度工作范圍內,針對-10~＋10 A范圍內的電流采樣實現優于5%的采樣精度。Current sensing plays an important role in controlling,monitoring or ProtectIOn functions of power systems.To meet the current sensing requirement of bidirectional DC/DC converters,a high-accuracy bidirectional current sensing circuit is proposed.The proposed current sensing circuit inserts a resistor in the path of the current to be sensed,while the current mirror and biased current circuit are introduced.Therefore,the bidirectional current can be expressed by positive voltage.By theoretical analysis and simulation,the sampling theory is analyzed and four biased current circuits are compared.At last,experimental results verified the proposed method.It is demonstrated that the proposed current sensing circuit can achi...
