| 摘 要： | 为了保证示波器的量值溯源，在LabVIEW环境下利用NI模块化仪器建立示波器检测系统来实现示波器的现场计量测试。根据虚拟仪器的设计思想，将NI功能模块利用PXI总线连接起来。利用VISA函数进行USB、RS-232、GPIB等各种接口的仪器通信。采用IVI驱动被测示波器，实现各种接口的模拟示波器和数字示波器的检测。在此基础上，通过模块化仪器的组合使用能够实现示波器、信号源、数字万用表、频率计等通用仪器的检测，系统功能可以得到极大扩展。推广应用前景广泛。

| Abstract: | To insure the oscilloscope can be trace to the value of a quantity, this paper proposes a design of the oscilloscope＇s testing system that can realize the test in locale based on LabVIEW ＆ modular Instrumentation. According to the virtual instrument principle, we can connect the NI modules with the bus of PXI, accomplish the communication of USB, RS-232,GPIB interface with VISA,and the oscilloscope is drived by the IVI , realize the test of the stimulant or digital oscilloscope. Based on the system, we can also realize the test of signal generator, cymometer and digital multimeter through the modular Instrumentation＇ s combination. The system＇ function can be extend by a long way and has a comprehensive foreground. |
