Virtual Arbitrary Waveform Generator And The Design Of The Virtual Oscilloscope And Remote Control

The combination of computer technology and measure technology make a kind of new measure instruments--virtual instruments. Virtual instruments is a kind of instruments of functional meaning, it is composed of personal computer, hardware and applied software. The basic principle is the hardware acquires singles, then using the software to realize data displaying and measurement. Along with the development of communication and network technology, the networked virtual instruments appeared. Networked virtual instruments implement networked measurement, which is the outcome of virtual instruments integrate with network communication technology.Based on the software LabVIEW of virtual instrument and data acquisition card of NI, the virtual arbitrary waveform generator and virtual oscilloscope are designed in this thesis. The virtual arbitrary waveform generator has such functions as arbitrary waveform loading, gain controlling, de offset adjusting, filters setting up. The virtual oscilloscope not only has the functions achieved in traditional scope such as waveform display and control, but also achieves some expanded functions. For example, the parameters can be measured and displayed automatically, the waveform can be saved and the frequency response can be analyzed.Ultimately, this thesis sums up several means of LabVIEW to realize communication through network such as TCP or UDP communication, DataSocket, Web Server and remote panels technology.
