目录一、 SAGEM OT490简介二、使用OT490直接进行测试1、测试菜单详述三、使用法国SAGEM公司OT DRIVE PC及WELLPHONE进行CQT测试1、硬件要求2、软件安装3、软件使用说明4、其他四、使用法国SAGEM公司OT DRIVE PC及WELLPHONE进行数据业务测试一、SAGEM OT490简介SAGEM OT490是一种用于E-GPRS网络测试，并可实时显示移动网络服务小区和6个相邻小区数据的专用测试工具。

使用者可根据具体情况，进行特定的测试，即对任一信道或任一网络参数进行测试。

同时，可通过数据接口与PC机连接，使用后台分析软件对测试数据进行分析。

SAGEM OT490是网络运营管理者和网络维护人员日常必备的网络测试工具。

SAGEM OT490用于E-GPRS及(GSM900/DCS1800/PCS1900 )网络测试。

在OT290的基础上又增加了几项主要功能，例如：测试EDGE网络，手机内部增加了JAVA开放平台，Micro SD卡存储，蓝牙GPS，视频及语音输出等功能，所有这些都使得手机成为一部便携式的路测设备。

二、使用OT490直接进行测试在介绍菜单之前，先看一下手机几个特殊按键：Volume/Zoom: 调节音量大小Camera: 一键开启照相机Central SoftKey: 中心键，使所有的选择生效Left/Right softkey: 左右键，和显示在屏幕左右方的功能关联下面是SAGEM OT490 网络测试操作步骤：1、测试菜单详述操作按键：按特定中心键，进入矩阵菜单,它显示OT490的功能界面，并直接指向测试菜单，如下图：点击“选择”进入各个测试菜单：TEST TOOL 1 Trace(跟踪信息)2 Forcing（强制功能）3 Scaning (扫频功能)4 Trace storage (跟踪信息存储)5Infos&Settings (设置功能)若需退出主菜单，按‘back’键进入主菜单以后，按▲键或▼键，可选择某一项功能注释：☆在测试菜单中，ACTIVE表示该项功能被激活，IN ACTIVE表示某项功能没有被激活。

CDS软件使用

TD-LTE路测工具CDS介绍一、工作模式和状态CDS软件集成了路测需要的前、后台所有功能，主要工作于两种模式：数据采集模式、数据分析模式。

两种工作模式之间需要通过“空闲”状态进行过渡。

如下图所示（注意：连接设备采集数据前必须先关闭已打开的日志文件，打开日志文件进行回放或分析前必须先断开不实际设备的连接。

）工作状态 Idle (空闲) 状态：当测试软件启动，但没有不测试设备进行通讯，也没有打开日志文件时处于的Idle状态。

Connected（连接）状态：此状态软件采集设备上报的数据并通过测试视图实时显示，但测试数据不会记录到日志文件中。

Recording（录制）状态：此状态不Connected状态的区别在于采集的数据同时会被记录到指定的日志文件中。

LogOpened（日志打开）状态：当用户打开一个或多个测试日志，但没有对日志文件进行其他操作时，软件处于LogOpened状态。

ReplayPause（回放暂停）状态：当用户打开测试日志文件后，且没有处于动态回放时则为此状态。

此时所有视图的显示不回放进度区间指示保持同步。

Replaying（普通回放）状态：当用户打开了日志文件后，点击“回放”按钮进入此状态，此时软件动态显示采集的测试数据。

FastReplaying（快速回放）状态：当用户打开了日志文件后，点击“快速回放”按钮进入此状态。

在此时数据将以数十倍于采集速度进行快速回放，用户可以使用“+”和“-”按钮来调节回放的速度。

二、CDS文件管理CDS使用两种专用的文件格式：日志文件（.log）和工作区文件（.wks）和日志文件用途：此文件用来保存采集的测试数据，用户可打开日志文件进行回放和后处理工作。

CDS支持用户同时打开多个日志文件，并可随时在打开的多个文件中进行切换回放工作区文件用途：此文件用来保存用户对CDS的配置信息，用户可根据需求建立多个工作区文件来快速恢复使用场景。

可存储三类配置信息：1、硬件配置2、自动测试计划配置3、视图配置三、CDS界面整体介绍CDS用户界面可以分为操作界面和视图界面两个部分：操作界面：图中蓝色箭头部分，包括标题栏、工具栏、导航栏以及资源管理器，大部分的CDS配置和控制操作从此部分收起。

cds测试软件使用及测试步骤

CDS软件的使用及步骤本次使用的是CDS7.1版本，正版软件需要用狗来解锁。

1软件介绍软件打开界面，我们需要点击软件的三叶草形状的基站，然后会出现下面的界面然后点击“文件“下面的csu出现这个画面这个是将工参导入，点击打开小区文件会让你选择工参，（一般都放在桌面上，首次需要导入，以后就不需要的，除非工参更新）选择好工参以后会出现下面的情况将ENB ID ENB NAME 小区号点上点击导入会出现导入成功，然后点击cdb会出现以下界面打击打开然后点击第五个“创建小区图层”点击“生成图层”并“保存模板”然后关闭即可。

然后点击上面一排菜单的工具一栏选择第一个“小区数据选择”出现该界面将工参激活确定即可。

然后点击设备，将gps和测试机连接好，再点击“连接/断开设备”.连接完成之后再下图的右面就会有gps信号（前提在能搜到卫星的情况下）在右侧小区图层小窗口上点击+号添加工参将工参打上对号即可关闭。

这时右面就会出现小区所在位置。

配合测试的软件还有FileZilla Client这个下载软件，这个大家都知道怎么用，我就不详细介绍了，到每个地区所用的服务器不同，这个去地势都会给。

以上连接成功后就可以测试了.2Log录制的介绍从上图可以看见dt indoor 一个是切换一个是室分Dt界面在右上角可以看见经纬度（每次都需要采集经纬度，本次没有搜到卫星，未能显示）Indoor界面这两个见面都能看见小区名称rsrpsinr等一些相关数据（我的截图是在屋里gps没信号所以没显示小区名称）在用户家里录log的时候在indoor界面的右侧竖排第三个点击导入一张白图（事先准备好的）箭头标注的即是。

导入白图之后点击log录制的图标（上面带+号的）点击之后出现一下界面，这个界面是让你起名并将long保存在什么位置。

点击保存之后log就开始录了，这时我们点击右面一列的第四个，然后再白板上打点，并在用户家里走动（测量信号的不同地方的好坏，打点只需打一个正方形即可，每个角点一下，一共点5下，两个点之间需要一段时间，根据你的速度而定）先面试点5个点的图这时可以点击log的图标停止了。

CDS参数设置详细说明(逐步逐项进行设置)

测试前的准备（1.确认安装好了软件及硬件驱动，如CDS 5.0+及SAGEM驱动、GPS 驱动，2.进行连接前的初始化 3.创建3个拨号连接）SAGEM USB Mobile pseudo CDC Modem ，该modern 为拨号的数据口，先双击设置初始化命令：+cgdcont=1,"IP","cmnet";+cgdcont=2,"IP","cmwap"诺基亚连接初始化命令：+cgdcont=1,"IP","cmwap"。

创建名称为“cmnet“和”cmwap“的拨号连接，拨号号码分别是：“*99***1#”，“*99***2#”、、“nokia”，拨号号码为“*99***1#”。

1．新建工作区，添加设备，设置端口，连接设备。

此处方框内的端口号填写SAGEM手机对应的端口号（数值一般是modem端口号+1）和GPS 对应的端口号。

SAGEM端口查看方法：双击图示选项后，在出现的页面内“调制解调器”标签下面看到。

双击后出现的页面：GPS的端口号，直接在“端口”选项内查看，是一个串口号。

AT串口参数会自动设置2. 测试项目设置进行DT时，需要设置如下参数：1)增加测试项目“FTP download“2）.双击进行详细设置。

CDS测试流程

CDS测试流程一、安装CDS软件，终端驱动软件注意msxmlchs.msi、vcredist_x86的文件安装Sony一般为手动选择如下对应目录进行驱动更新，以设备管理器为准进行查看软件对应sony终端需要修正替换一下DeviceCOM.ini文件三星为终端程序安装，一般为自动识别终端启动软件注意右键“以管理员身份运行”二、运行CDS程序，按测试分组，打开工作区三、选择终端端口。

（建议每连接一个终端，就选择一次端口号，同时保存工作区。

这样在后面测试过程中，就不再需要选择）。

数据业务测试：使用1、3、4号端口语音业务测试：使用1、2、3号端口1.注意添加设备类型对应Qualcomm，还是His，或者其他2.通过软件控制UE进行attach、dettach，根据信令窗口能够输出对应信令流程，判别端口是否正确四、修改ftp上传、下载、语音和短信业务属性3.ftp上传、下载服务器地址（一般选择所在地对应省市服务器）。

4.被叫号码。

将所有Voice CALL选项改成索尼终端的号码5.短彩信配置：将短信中心号码修改成USIM卡所在地的短信中心号码。

将短、彩信的接收端号码修改成索尼手机号码6.邮件设置：填写用户自己的139邮箱7.完成配置后，连接设备，正常连接后，终端属性信息应显示如下。

若不是此种显示，就断开连接重新选择端口号进行重新连接五、测试中，若事件窗口出现no device message，或者听到CDS软件的告警音，则表示终端异常。

此时请停止CDS测试，重新插拔手机，连接好后，继续测试六、注意log录入及命名保存七、注意注：测试过程中若更换手机则要更改端口；更换sim卡需修改被叫号码及短信中心号码；更换ftp服务器地址。

t490 电池阈值

t490 电池阈值T490电池阈值随着移动办公的普及，笔记本电脑的使用频率越来越高。

然而，随着使用时间的增加，电池容量逐渐下降成为了一个普遍存在的问题。

为了更好地管理电池的使用，ThinkPad T490采用了电池阈值功能，帮助用户延长电池寿命，同时提供更好的使用体验。

电池阈值是指在一定的电量范围内，用户可以设置电池开始充电和停止充电的阈值。

通过合理设置电池阈值，可以最大程度地延长电池的使用寿命。

在ThinkPad T490中，用户可以通过预装的Lenovo Vantage应用程序进行设置和管理。

我们来了解一下电池阈值的原理。

当电池充电到一定的阈值上限时，电池充电会自动停止，以避免过充。

同样地，当电池放电到一定的阈值下限时，电池充电会自动开始，以避免电池过度放电。

通过设置适当的上下限，可以避免电池长时间处于满充或过度放电的状态，从而减少电池的寿命损耗。

在设置电池阈值时，用户可以根据自己的使用习惯和需求进行调整。

一般来说，如果用户经常使用电源适配器供电，可以将上限设置得稍低一些，如80%左右。

这样可以减少充电次数，延长电池的使用寿命。

而如果用户经常使用电池供电，可以将上限设置得稍高一些，如90%左右。

这样可以提供更长的续航时间，满足用户的移动办公需求。

除了上下限的设置，ThinkPad T490还提供了一些智能的电池保护功能。

例如，当用户长时间不使用电池时，系统会自动将电池充电至一定的阈值，然后停止充电，以减少电池的寿命损耗。

此外，当用户电源适配器供电时，系统也会自动停止充电，以避免过充现象的发生。

通过合理设置电池阈值，用户可以延长电池的使用寿命，并提高笔记本电脑的使用体验。

使用ThinkPad T490的电池阈值功能，用户可以轻松地管理电池充放电状态，避免了频繁充电和放电对电池寿命的损害。

同时，用户可以根据自己的使用需求，灵活调整电池阈值，以满足不同场景下的续航和性能需求。

电池阈值是ThinkPad T490提供的一项实用功能，可以帮助用户延长电池寿命，提高使用体验。
