德力ds2100误码率场强仪使用说明书
场强仪使用方法
场强仪使用方法,场强仪操作说明，数字有线电视改造用场强仪场强仪简单说明：场强仪故名思议就是测量场强（电平）的仪器。
它可以满足电视、调频、有线电视系统的场强（电平）、图像/伴音比、载波/噪音比、数字频道功率、频谱分析仪、HUM、互调、回传评估的高精度测量。
该产品配有一块液晶显示屏，可以直观地显示出测量数据。
场强仪基本功能键说明如下图：一.场强仪单频道测量按下CH/F键,仪器进入单频道测量模式,液晶显示界面如下:此时屏幕左下方显示当前的频道号,右下方显示当前频道的图像载波频率值,屏幕中部左方显示当前频道的图像载波电平,右方显示当前频道的V/A值(图像载波电平与伴音载波电平差).按上下键可加减频道数.二.场强仪双频道测量/斜率测量首次按下斜率键,仪器进入的是双频道测量模式,液晶显示界面如下:此时屏幕的左下方显示第一个频道的频道号,右下方显示第二个频道的频道号,屏幕中部左侧显示第一个频道的图像载波电平值,右侧显示第二个频道的图像载波电平值.在双频道测量模式下再次按下斜率键仪器进入斜率测量模式，液晶显示界面如下:此时屏幕左下方显示第一个频道的频道号,右下方显示第二个频道的频道号,屏幕中部左侧显示第一个频道的图像载波电平,右侧显示斜率值(即第一个频道的图像载波电平减去第二个频道的图像载波电平的差值)按上下键可以加减频道数,按换档键可以控制在第一个频道和第二个频道之间切换.场强仪说明:1. 此功能可用于测量/调试干线放大器的参数.2. 此功能可用于测量国家<CATV行业标准>中规定的任意频道间的电平差及相邻频道间的电平差.3. 此功能可同时测量两个频道的电平值,非常适合CATV维护人员使用.场强仪图片:场强仪使用方法:①正确连接电缆，连接电缆不宜过长。
假若非用长电缆不可时，则必须在仪表的读数上加上电缆的损耗，尤其是高频段。
②场强仪不仅要测量图像载波电平，还要测量调频声音广播信号载波电平,因此，所用信号电平应包括声音载波电平和图像载波电平。
Protek 场强测试仪使用手册
Protek 场强测试仪使用手册场强测试仪能够测试某一地点的某一频率的信号的功率和某一地点有多少个在用的频率和各自的功率，还可以做为频率计使用，测量某一信号的频率，但这个不经常使用。
场强测试仪的操作界面介绍：RUN（GHZ）键：开始按键，设计好开始测量后，按RUN键，停止的话，再次按RUN键。
也是设置频率时的单位GHz。
MODE（MHz）键：该键的作用是设置信号的调制方式，所设置的调制方式要与所测信号的调制方式一致。
支持四种调试方式，分别为W-FM(宽频调制)、N-FM(窄频调制)、AM（幅度调制）、SSB（单边带调制）没按一次按键在屏幕最上边的一行依以上次序顺序变化显示。
我们测试用W-FM 调制方式。
另外，该按键还用来输入单位MHz。
SWEEP（KHz）键：该按键是设置触发模式的，没按一次该案件在屏幕的第一行的第三个位置，会一次变化显示F、S、1这三个字母。
其中F代表Free RUN即自由触发模式，这种触发模式是始终在刷新触发频率，S代表Squel RUN即连续触发，1代表Single RUN即一次触发，在该模式时，按运行键，在频带范围内只触发一次。
另外，该按键还用来输入单位KHz。
MATKER(Del)键：该键的功能是对频率进行标记和选择测试，以记忆和选择在频谱范围内的不同的测试点。
按该按键会在屏幕的最上边一行的最后边依次显示NONE、M、Δ、S，他们的含义分别为：M为MATKER代表单一标记，这时在屏幕上出现一个1的标记点，Δ为DELTA MARKER 是两个标记，其中只有标记2可以活动，1作为基准，S是SQUEL MARKER，是噪声标记，通常指我们所说的噪声比，通常设置为-100。
同时，该按键还是在输入时的删除键。
0~9数字键：主要是在输入频率的时候使用；Shift键：按该键，屏幕最上边显示为shift时，屏幕下方显示STAR、STOP、STEP，分别代表起始频率，终止频率，和频率步梯，再次按该按键，当屏幕显示3201时，屏幕下方显示CENT、SPAN、STEP分别代表中心频率、频带宽度和频率步梯，其实两者的实际意义是一样的，只不过是显示的方式不一样而已，另外，对于我们所测的频谱带宽，需要与电脑相连进行设置，缺省模式下固定为20M。

误码仪的使用说明 1将误码仪电源及收发两根线接好。 2 按下Power 左边的红色按钮，打开误码仪。 3 若误码仪的液晶显示屏显示如下类似界面：下 00 21：42：27 Stop BE 0 ACC BER 0.0E—12 * * * * 2Mb PRBS15 * * * * 则说明误码仪各项设置均正确，并且液晶显示屏下面的四个指示灯均熄灭，此 时将Start/Stop左边的按钮按一下，开始计数即可。其各行解释和调节方法如下： 第一行 00 21：42：27 Stop 从左到右依次为： 天 小时：分钟：秒钟, Stop 表示当前计数状态为停止，可按一下Start/Stop 旁边的按钮使其处于运行壮态 Run。 第二行 BE 0 ACC BE表示误码， 0表示误码个数，ACC 表示误码统计，可 通过按 BE/BER 键找到另外两个选项Cur Max。 第三行 BER 0.0E—12 BER表示误码率，0.0E—12显示当前的误码率。 第四行 2Mb PRBS15 2Mb 表示速率, PRBS15表示当前使用的码型，可通过依 次按Start/Stop键，Set Up键，Select左边的 > 键，使液晶显示器上的光标停在右 下角图案区的第一个图案上 ,再按∨键可选到PRBS15 选项。
