扫描网络中IP的网段，其中ip地址可以由自己任意选择-Scan network IP of the network segment, in which ip address can choose from their own

在虚拟仪器中，计算机成为仪器的一部分，使得计算机可以得到充分发挥。除了仪器的输入、输出、数据处理分析、结果显示由计算机完成外，还可组成计算机网络。一个大的复杂的测试系统往往系统的测量、输入、输出、结果分析分布在不同的地理位置，仅用一台计算机并不能胜任测试任务，需要由分布在不同地理位置的若干计算机共同完成整个测试任务。-In the virtual instrument, the computer has become part of the equipment so that the computer can be brought into full play. In addition to equipment import, export, data processing, analysis, results showed that the completion by a computer, the computer network can be formed. A large test systems are often complex system of measurement, input, output, results in different geographical location, just a computer and can not do the test tasks, the need for different location in a number of computers together to complete the test任务.
