The e4356a has all of the features found on our general purpose system dc power supplies , such as the agilent 6670 series of 2000 w system dc power supplies E4356a具备我们通用系统直流电源，如agilent 6670系列2000w系统电源的全部功能特性。
This might indicate a weak or charging battery , a transition between ac power and battery , or another change in the status of the system power supply 这可能指示电池电力不足或正在充电、电源正由交流电转换为电池或相反，或系统电源状态的其他更改。
A system power status notification can occur when a weak or charging power source is detected , or when a transition from ac or battery power source occurs 事件。会在以下情形下出现系统电源状态通知：当系统检测到电源不足或正在充电时，或者当交流电源和直流电源之间相互转换时。
This article discusses process and character of disturbance occuring by the experiment and theoretical analysis , it also puts forward the antijamming means of the microcomputer system power source 通过实验和理论分析，对干扰产生过程和特性进行了讨论，提出了微机系统电源抗干扰的办法。
Secondly according the selected motors , we design the brushless dc motor driver circuit based on chip si9979 , the main control circuit based on microcontroller dsp 2810 and power and communication circuit 其次,根据选用的电机,设计了以si9979芯片为核心的无刷直流电机驱动电路;设计了以dsp2810为核心的主控电路;同时还设计了系统电源电路和通讯电路。
Only regeneration energy can be selected for system power supply for complex and across distribution of rivers , which brings to the system power consumption an outstanding problem , optimization for power consumption was full considering in this thesis 由于航标灯工作于野外，分布错综复杂，因此只能选择可再生电源作系统电源。相对有限的电池供给使得系统功耗成为一个突出问题，系统从元件选择到软硬件设计对功率进行了优化。
Based on the requirements of the system the power source , amplify circuits , data gathering and storage circuit and reset circuit were designed . the software of this system was programmed with c language of mcs - - 51 single chip microcomputer that is a language of structijral programming language , cofltains many " characters of advanced ianguages and has the functions of assemble 1anguage . the software of the system was designed with structural program module that make the sttucture of software clear and convenience debug and modify 其中系统硬件设计主要是采用mcs ? 51单片机为肌肉嫩度测量仪的核心，进行了系统电源设计、放大电路设计、数据采集和存储电路设计、复位电路设计；软件设计使用单片机c ? 51语言，它是一种结构程序设计语言，兼顾了多种高级语言的特点，并具备汇编语言的功能，根据程序设计原理，采用结构化程序设计，使软件结构清晰。
