基于LabVIEW的虚拟信号发生
信号发生器是各种科研实践中最重要的仪器之一。传统的大多是由硬件组成的，但是其结构比较复杂，维护性和操作性也不好。随着现代科技的发展，信号发生器的设计种类也有很多，价格差异很大，性能也越来越完善。虚拟仪器的主要平台应该是LabVIEW，为了给那些用C用习惯的人使得。LabVIEW的最大特点是傻瓜似的编程，为了把工程师从繁琐的编程中解脱出来，LabVIEW实现了测试仪器模块化，使测试配置更加灵活，

Signal generator is a variety of research practice one of the most important instrument.Mostly by the traditional hardware, but its structure is complicated, maintenanceand operational is not good.With modern technology, the design of the signal generator, there are many types, prices vary widely, performance, become more perfect. The most important feature of LabVIEW programming is a fool, in order to engineer from the tedious programming freed, LabVIEW implements modular test instruments, making the test more flexible configuration, the design developed by National Instruments virtual instrumentation based on virtual signal generator, and traditional instruments compared to the price compared to cheap, simple, practical wide range of simple design and so on. The actual needs of the user can use the LabVIEW (a graphical editing language) design features of the virtual instrument. Can also be released through the network, then the client can remotely view and control a virtual signal generator. The main work is to combine the virtual instrument technology, arbitrary waveform signal generator of research and design.
First, the paper introduces the basic theory of virtual instrument technology, including virtual instrument concept, composition, classification, and virtual instruments compared with traditional instruments .On this basis, virtual instrument system software architecture, describes a simple instrument drivers, VISA and other related technologies. Secondly, the paper was arbitrary waveform generator software design. Which mainly include the formation of any analog signal digital signal generation, analog, digital signal modulation, the actual signal plus noise, and hand-painted arbitra

在LabVIEW中，我应该怎么实现对串口中的DTR和RTS信号线的控制？
您可以通过程序框图中的VISA属性节点（Property Node）中的Modem Line Settings里的属性来读、写串口中的DTR和RTS等控制线。LabVIEW 6.x, 7.x请根据以下步骤放置VISA属性节点并选择Modem Line Settings：在LabVIEW的程序框图，放置一个属性节点（Functions Palette » Instrument I/O » VISA » VISA Advanced）。右键点击属性节点，然后选择Property；选择Properties » Modem Line Settings.选择相应的设置属性（Line CTS State、Line DCD State、Line DSR State、Line DTR State、Line RI State或Line RTS State）。LabVIEW 5.x请根据以下步骤放置VISA属性接点并选择Modem Line Settings：在LabVIEW的程序框图，放置一个属性节点（Functions Palette » Instrument I/O » VISA）。右键点击属性节点，然后选择Property；选择Properties » Modem Line Settings.选择相应的设置属性（Modem CTS State、Modem DCD State、Modem DSR State、Modem DTR State、Modem RI State或Modem RTS State）。请注意：您可以通过属性节点读、写串口的DTR和RTS控制线，但是对于以上列出的其他控制线，您只能通过属性节点作读操作。右键点击该属性节点并在快捷菜单中选择Change To Write，可以对相应的控制线作写操作；同样的，右键点击该属性节点并在快捷菜单中选择Change To Read，可以对相应的控制线作读操作。
