This paper presented the main functions and characteristics of Multisim8.0, and the main qualities of high frequency tunable amplifier such as voltage gain, transmission bands and selectivity were studied using simulation analysis and testing technologies of Multisim 8.0. The results are visual and precise, and prove the theory very well. This software has powerful simulation and analysis function, by which the analysis and design of high frequency circuit are not only more precise and credible, but also more closed to the real circuit running status.

本文介绍了Multisim8.0仿真软件的主要功能及特点，并结合该软件对高频单调谐放大电路的电压增益、通频带、选择性等主要质量指标进行了测试与仿真分析，结果直观、精确，很好地验证了理论，表明该软件有强大的仿真和分析功能，在实现高频电路分析和设计方面不仅高效、可靠，而且具有逼近真实电路的效果。

Cable .Make use of this principle, we can quickly locate the target cable or break point from large amount of cables, under carpet, the inner of decoration wall and over ceiling1 operation is simple , reliable , the interface is nimble , use is broad , bionic form , carry-over are convenient, since our link tester has two signal output port, it can work when switch is running, this is very convenient. 2 applies to all metal cable such as network cable , tele phone line cable , video cable , automobile circuit .it can not be work with high voltage(above 80V),if you want to locate it ,please turn off the cable power supply3 can test the telephone line polarity, connectedness, rough position of breaking point.4 uses the two crocodile clamp to avoid getting rid of the job of make network cable. Use the RJ45/RJ11 interface can connect to the network and the telephone line directly.5 link tester can find out that pair of circuit line cable from large mount of cables. 6 high amplitude ranks 200 times amplification circuit is sui table to locate long distance cable.7 two-sided network lines sequence indicator is easy to examine the network line cable whether or not correctly conveniently. 8 portable types multifunctional bag can encase most of your engineering tools; remit your messy carry-over of implement bothering. 9 adopt two 9V batteries.

线路通产品特点：1 操作简单、性能可靠，接口灵活、用途广泛，仿生外形、携带方便，由于本设备采用了信号双路输出方式，可以解决交换机工作状态下使用，避免了关掉交换机影响其他线路的使用的麻烦。2 适用于查找网络电缆、电话线路、视频电缆、汽车电路、无强电状态下的所有金属电缆。3 可以测试电话线路极性、连通性，断点大概位置。4 两个鳄鱼嘴夹，避免了去做水晶头的麻烦，RJ45/RJ11接口线，可直接连接网络和电话线模块。5 寻线器快速地在众多紊乱的线路中找出需要查找的那一对线路线缆。6 高音频振幅级别200倍的放大电路，适合长距离电缆定位。7 双面网络线续灯可以更直观方便的检查校正网络线续线路连接是否正确。8 便携式多功能软包，可以把您工程施工、维护的基本工具装齐，免除您工具散乱携带的麻烦。9 本寻线器采用2节9V电池。
