About this Standard
EMVA has started the initiative to define a unified method to measure, compute and present specification parameters and characterization data for cameras and image sensors used for machine vision applications. The standard does not define what nature of data should be disclosed. It is up to the component manufacturer to decide if he wishes to publish typical data, data of an individual component, guaranteed data, or even guaranteed performance over life time of the component. However the component manufacturer shall clearly indicate what the nature of the presented data is. The Standard is organized in different modules, each addressing a group of specification parameters, assuming a certain physical behavior of the sensor or camera under certain boundary conditions. Additional modules covering more parameters and a wider range of sensor and camera products will be added at a later date. There are “COMPULSORY” modules, of which all measurements must be made and of which all required data and graphics must be included in a datasheet using the EMVA1288 logo. Further there are “OPTIONAL” modules which may be skipped for a component where the respective data is not relevant or the mathematical model is not applicable. Each datasheet shall clearly indicate which modules of the EMVA1288 standard are enclosed. For the time being it may be necessary for the manufacturer to indicate additional, component specific information, not defined in the standard, to fully describe the performance of image sensor or camera products, or to describe physical behavior not covered by the mathematical models of the standard. It is possible in accordance with the EMVA1288 standard to include such data in the same datasheet. However the data obtained by procedures not described in the current version of the EMVA1288 standard must be clearly designated and grouped in a separate section. It is not permitted to use parameter designations defined in any of the EMVA1288 modules for such additional information not acquired or presented according the EMVA1288 procedures.

R/W (Read/Write Input) –WR
CS (片选输入) –CS 当VCC 低于4.25 V时，DS12887 从内部禁止对外部CS的操作。此时，时钟和RAM 都被保护起来。
IRQ (中断请求输出) – 当中断状态位和对应的中断允许位有效时，IRQ的输出保持为低。复位和读C寄存器都可以清除IRQ中断信号。没有中断时，IRQ呈高阻状态，其他中断源还可以挂接到中断总线上。由于IRQ是漏极输出，所以需要外接上拉电阻。

2.1线性信号模型如图1所示，数字图像传感器实际上是将曝光时间内的光子通过一系列步骤转换成数字。

在曝光时间内，平均µp光子冲击单个像素。

整个量子效率的一小部分吸收并积累µe电荷单位。

这里定义的总量子效率是指单个传感器elementpixel所占用的总面积，而不仅仅是光敏感区域。

因此，这个定义包括填充因子和微透镜的影响。

在公式(1)中表示，量子效率取决于光子辐照像素的波长。

在暴露时间t exp内，与区域a相对应的光子的平均数目，可以通过以W / m2为单位的传感器表面的辐照度来计算使用著名的电磁辐射的能量量子化单位hν。

【精品】短波收音机收听手册

短波收音机收听手册当下市面上的全波段（WorldBand）数调短波收音机调谐的频率跨度很大，典型的调谐范围从150KHz到30000KHz,几乎囊括长波、中波、短波的全部波段。

根据国际无线电联盟的协定，无线电频率被划分并供应给不同用途的使用者。

虽然偶有犯规者，但绝大多数台(站）都恪守许可使用的频率.150KHz及以下.这个频率的无线电波不能通过电离层传播，却可以很好地穿透海洋的深处，因此，在这个频率下可以发现许多做潜艇通讯的军事电台.德国、英国、日本、瑞士和白俄罗斯等国的标准时间标准频率发播台的发射频率都在20-80khz之间,普通收音机是根本接收不到的。

150到540KHz。

这是BCLer和Dxer通称的长波段。

在收音机里能听到的大多数信号是一些信标台不断重复摩尔斯（Morse）电码呼号.长波广播从153KHz启用，大功率的长波广播以俄罗斯和东欧国家为甚，非洲及澳大利亚、蒙古和前苏联加盟共和国等部分亚太地区国家也有长波广播，但我国广播并未染指这一领地。

法国标准时间标准频率发播台使用162khz.在长波的高端，可以接收到一些RTTY(无线电传）信号。

海洋气象和安全广播,如无线电爱好者熟知的VTEX(航行警告自动通信系统)就是在512KHz发射。

这个波段的最好接收时间是秋冬季的夜晚。

我国的北方地区容易接收到独联体国家的长波广播。

540KHz到1710KHz。

这是中波广播.亚洲和中南美洲地区的中波起始段被划为530KHz。

传统收音机的中波到1600KHz结束，而实际意义上的中波广播波段却在1710KHz结束。

从1610到1710KHz是新的中波扩展领域,从1997年开始,不断有电台在这一波段上播音,给无线电爱好者提供了精彩的DX（远程无线电接收活动)契机。

但1700khz以上频率入驻的中波广播电台寥寥无几，据WRTH(《世界广播电视手册》）最新记录，全球仅有两家广播电台在1700khz—-1710khz发声，澳大利亚转播当地赛马和服务偏远地区土著民的广播电台就使用1701KHz,阿根廷RadioPalacio—AM1710电台使用1710KHz,发射功率均在1KW以下，远程接收极具挑战性。

FM收音机_RDS功能概述及编码

FM收音机_RDS功能概述及编码RDS功能的FM收音机概述及编码介绍所谓RDS是英国BBC广播公司开发的一种特殊无线电广播。

即“无线数据广播系统”（Radio Data System). 它是在调频广播发射信号中利用副载波把电台名称，节目类型，节目内容及其它信息以数字形式发送出去。

1概述通过具有RDS功能的调谐器就可以识别这些数字信号，并做响应处理，RDS广播精髓在于其AF和TA功能，AF既自动频率调整，当信号低于某个水平时，AF功能会自动搜索当前电台的其他发射频率串。

2功能RDS收音系统还独有“交流信息”功能（TA功能，也称交通公告），若有紧急事件，电台就会发送特殊信号，令收音机强行播放，另外，还有时间基准发射，自动调准收音机时间等功能，RDS在汽车，手机等移动设备上使用很方便。

3电台支持目前国内支持RDS的电台已知的有：上海FM91.4 中央人民广播电台经济之声北京FM88.7 中国国际广播电台HIT FM上海FM87.9 中国国际广播电台HIT FM广州FM88.5 中国国际广播电台HIT FMRDS是英国BBC广播公司开发的一种特殊的无线电广播，称“无线数据广播系统”(Radio Data System)，它是在调频广播发射信号中利用副载波把电台名称、节目类型、节目内容及其它信息以数字形式发送出去。

通过具有RDS功能的调谐器就可以识别这些数字信号，变成字符显示在显示屏上。

在收到节目的同时，通过RDS可知道接收到的是那个电台，它的发射频率，并给出该电台其余的频率，由此再使用“切换频率”钮来保证所接收的信号为最强的频率。

RDS无线数据广播文件可显示接收到的节目名称及其它资料。

RDS功能可按节目类型决定取舍，寻找到符合你要求的电台。

RDS还能用来自动控制接收机，使流动工作的汽车收音机一直保持最佳接收状态，及时收到紧急交通报告，有利交通安全。

RDS 除使收音机自动化、高档化外，并在城市交通管理中发挥作用，其使用领域尚在拓展中随着发展，会有越来越多的电台具有RDS广播功能，RDS可以显示电台名称、节目类型、节目内容、日期时间及其它信息，而它具有的AF和TA功能，则更强大。

TEL T826 827 FM基站传输器与激发器说明书

1T826/827 General InformationThis section provides a brief description of the T826 transmitter and T827 exciter, along with detailed specifications and a list of types available.The following topics are covered in this section.Section Title Page 1.1Introduction 1.31.21.2.11.2.21.2.31.2.41.2.4.11.2.4.21.2.4.31.2.51.2.6SpecificationsIntroductionGeneralRF SectionAudio ProcessorInputsModulation CharacteristicsCTCSSMicrocontrollerTest Standards1.41.41.41.51.61.61.71.71.71.81.3Product Codes 1.9 1.4T826 Standard Product Range 1.10 1.5T827 Standard Product Range 1.101.1IntroductionThe T826 is a synthesised, microprocessor controlled FM base station transmitter designed for single or multichannel operation in the 66 to 88MHz frequency range1 with a standard power output of 25W. The RF section of the transmitter comprises a fre-quency synthesiser which provides 125mW of frequency modulated RF drive to a two stage, wide band output driver followed by a 25W power amplifier. A thermal shut-down feature is provided in the T826 in case operating temperatures exceed acceptable levels.The T827 is a synthesised, microprocessor controlled FM base station exciter designed for single or multichannel operation in the 66 to 88MHz frequency range1. With a stand-ard power output of only 1W, the exciter is designed for use with the T828 50W power amplifier. The RF section of the exciter comprises a frequency synthesiser which pro-vides 125mW of frequency modulated RF drive to a two stage, wide band output ampli-fier.A wide selection of audio characteristics may be obtained from the audio processor. Optional circuit blocks are an audio compressor and a pre-emphasis stage. They can be bypassed or linked to one or both audio inputs, and then back into the remaining audio circuitry in almost any combination. All audio processor options are link selectable. The synthesiser frequency is programmed via the serial communications port. Eight channel select lines are accessible via an optional D-range connector (D-range 2 -T800-03-0000) at the rear of the set.All components except those of the VCO are mounted on a single PCB. This is secured to a die-cast chassis which is divided into compartments to individually shield each sec-tion of circuitry. Access to both sides of the main circuit board is obtained by removing each of the chassis lids. There is provision within the chassis to mount small option PCBs.The front panel controls include line sensitivity, microphone socket and carrier switch. This switch turns on the carrier (unmodulated) as an aid to servicing.The T826 and T827 are both 60mm wide and each occupies a single space in a Tait rack frame, which has the ability to accommodate up to seven standard modules.1.Although capable of operating over the 66-88MHz frequency range, the T826 and T827have an 8MHz switching range (see Section 1.2.3 and Section 3.1).1.2Specifications1.2.1IntroductionThe performance figures given are minimum figures, unless otherwise indicated, for equipment tuned with the maximum switching range and operating at standard room temperature (+22°C to +28°C) and standard test voltage (13.8V DC).Where applicable, the test methods used to obtain the following performance figures are those described in the EIA and ETS specifications. However, there are several parameters for which performance according to the CEPT specification is given. Refer to Section 1.2.6 for details of test standards.Details of test methods and the conditions which apply for Type Approval testing in all countries can be obtained from Tait Electronics Ltd.The terms "wide bandwidth" and "narrow bandwidth" used in this and following sec-tions are defined in the following table.1.2.2GeneralNumber Of Channels ..128 (standard)1Supply V oltage:Operating V oltage ..10.8 to 16V DC Standard Test V oltage ..13.8V DCPolarity..negative earth only Polarity Protection..crowbar diode Line Keying Supply (if required) ..-50V DCSupply Current:Transmit - T826.. 4.5A (typical)- T827..650mAStandby..160mA (typical)Operating Temperature Range..-30°C to +60°CChannel SpacingModulation 100% DeviationReceiver IF Bandwidth Wide Bandwidth 25kHz ±5.0kHz 15.0kHz Narrow Bandwidth12.5kHz±2.5kHz7.5kHz1.Additional channels may be factory programmed.

二、实习要求：1、了解现代通信技术的发展过程2、掌握1008调频对讲收音机的安装顺序3、掌握1008调频对讲收音机的焊接技术4、了解集成电路芯片2822、1800的功能5、理解1008调频对讲收音机原理电路图6、完成两台机对讲和调试6、掌握焊接工艺。

三、实习内容：1008调频对讲收音机焊接（1）元器件介绍：【1-1】La1800芯片La1800为单片FM/AM收音机电路，F M部分包含混频，F M本振中放，FN鉴频，静噪，低通滤波器等；AM 部分包括高放检波，此外还有音频驱动级和功放电路。

芯片采用密间距的22脚双列直插封装，如图【1-2】D2822芯片用于收音机作音频功率放大器，经过CD2822放大后的音频信号从LA1800芯片输出，经过R10、C25、RP耦合至D2822芯片进行第二次功率放大，推动扬声器发出声音，该芯片包含两个放大二极管，工作电源电压范围为2.5V~5V。

采用密间距的8 脚双列直插封装，如图【1-3】电阻本实验中使用时色环电阻，色环电阻识别方法是因为电阻上面用了四道色环或者五道色环来表示电阻值。

四色环电阻中，第一色环是十位数，第二色环是个位数，第三色环是应乘颜色次幂颜色次，第四色环是误差率带有四个色环的其中第一、二环分别代表阻值的前两位数；第三环代表倍率；第四环代表误差。
