The Vxi Arbitrary Waveform Generator Waveform Editor Software Design

According to the high security and small volume in military weapon equip request, VXIbus flat roof have been applied to all kinds of weapon equip test and maintenance. The general signal sources represented by Arbitrary Waveform Generator(AWG) have become the most popular instruments in modern testing domains. AWG can not only generate conventional waves such as sine wave, triangle wave, square wave, etc, but also generate unconventional waves such as linear frequency modulation wave, phrase modulation wave, amplitude modulation wave etc, the most important, it can create arbitrary wave. So we can find AWG in communication, radar, navigation, space navigation etc fields.The software exploitation of VXI arbitrary waveform generator is the main aim of this task. It includes Soft Panel and Arbitrary Waveform Editor(AWE). The most important property in Virtual Instrument(VI) is that the traditional operate interface has been replaced by PC, we can use PC's powerful calculate and display capability to make intercommunicate between user and instrument more easy. I made LabWindows/CVI as the exploitation tool. Soft Panel is used to set wave parameters and control instrument generate corresponding waveforms. And AWE is the emphases and difficulty in the whole software design. It embodies the "arbitrary" character of AWG. It has all kinds of generating wave tools such as through mathematic formula, through waveform storage, input special points and insert other points. In other hand, it has many edit and process methods, for example, user can draw wave by hand, make arithmetic process, and can add window, filter wave, smooth wave etc. So it help us create all sorts of waveforms.The AWG model as ES14V21 has passed authentication in Beijing in Apl.2003, it is equal to the world level in later of 90'ages. Based on experiment, we can can prove the Arbitrary Waveform Editor has some characters ,it has powerful function in creating,editing,processing waveforms, and can be manipulated easily. In a word, it is satisfied to generate all kinds of arbitrary waveforms.
