  虚拟仪器技术不断地扩展其功能及应用范围。现在LabVIEW不仅能在PC上开发测试程序,而且可以在嵌入式处理器和FPGA上设计硬件。这一技术也将*终提供这样的一个独立环境,使用户可以从设计测试系统到定义硬件的功能,如图3所示。测试工程师将能使用合适的功能来进行系统级的设计。当他们需要定义专门的测量功能时,他们也将可以用同样的软件工具来“细化”到合适的级别以定义测量的功能。例如,工程师可以开发LabVIEW程序来使用模块化仪器进行某些测量,如DC电压和上升时间。当工程师需要开发专门的测量时,他们也可以使用LabVIEW对原始的测量数据进行分析,从而开发出专门的测量,比如峰值检测。如果在某些情况下他们需要使用一些新的硬件功能来实现测量,如定制的触发,那么他们可以用LabVIEW定义一个触发和滤波方案,并嵌入到仪器卡上的FPGA中。
