文档介绍：several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measuremen性标号
开关、继电器：K？
输出连接器〔如BNC，SMA〕：P？ 原理图：标注连接器的特性，如BNC母头，直插，标注为BNC-F-S，如果为90度，那么标注为BNC-F-R
磁珠：FB? 标注100M时候的阻抗值，如100M-600R
电气网络的命名标准：
采用英文命名，可采用缩写，但意义应尽量明确
如：
本地地址线：LA
本地数据线：LD
本地读：LRD
本地写：LWR
数字地：DGND，模拟地，AGND，输出地:OGND，电源地：PGND
电源：应明确标明电压值，分清模拟和数字电源，模拟电源用A开头，数字电源用D开头，如A+5V，D+5V，如属于芯片专用电源，还应注明芯片名称，如9739A+5V
参考时钟输入：RCLK_IN
采样时钟输入：SCLK_IN
触发信号输出：Trigger_OUT
工程设计初期准备：
1、明确电路原理，确定电路的框图，应结合本模块所要完成的功能技术指标逐项的分析
2、说明各模块的作用、模块间的连接线、电源需求，对功能模块的命名应该具有较强的可读性，命名采用英文
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
