Development Of Control System For Multifunctional RF Analyzer Based On LabVIEW

Hand-held radio frequency integrated tester is a kind of high-performance hand-held device,which includes seven measurement modes,Antenna and feeding test,Network analysis,Spectrum analysis,Power monitoring,USB power measurement,Vector voltage measurement and Field strength measurement.With the integration of a number of microwave test equipment,it can be used for various microwave parameter measurements and has a good applicability.In addition,it has advantages of small size,light weight,easy to carry and so on.This instrument greatly facilitates the use for the user,reducing the issues of handling and replacement of the equipment.Due to the site conditions,test environment and other restrictions,sometimes we need to keep the operator and instrument a certain distance with the test product in parameter measurements.To meet the testing requirements,it's necessary to develop a remote control system for the instrument.In addition to control the instrument,the control system can also process the measurement results when running on a computer,simplify the process of importing and exporting data files from the instrument.In this paper,the hand-held RF integrated tester is used as a controlled object,a control system for the instrument was developed on the computer based on Lab VIEW,which is convenient to control the instrument remotely.What's more,the software system can edit and save the measurement parameters.The main contents and contributions of this thesis are arranged as follows.1.Develope the control software system,which can realize communication between the computer and the instrument,send instruction to realize the long-distance control to the instrument,and switch to the different test module carries;2.Realize the information process function of the control software,collect and refresh the measured information regularly and send it to the computer.The data can be displayed in the form of data,dial and trace after processing,and the information can be edited,saved,recalled on the computer as well;3.Design a simple and friendly operation interface in the light of the instrument panel.With the realization of remote control and data processing,the software is used to optimize the operation of the instrument,can enlarge and reduce the traces according to the requirements,improve the quality of human-computer interaction.;4.Test the control software system.Make a confirmation of the functionality,stability ease of use of the control system by the way of manual debugging.
