Microwave Signal Generator Based on Qt/Embedded

At present,embedded applications have more and more requirements.It is important to select a GUI for our project.This paper introduces the feathers of some kinds of typical GUI,and it analyzes the main technology of Qt/Embedded emphatically.Using Qt/Embedded,Frequency Switching Time(FST) of the microwave signal generator deceased to 45 ms,single sideband phase noise is-75dBc/Hz,power accuracy is 0.52 dB.Other parameters suffice the demand of design fully.
