| Measure and test of mobile telephone is the important task for the test of instrument of wireless. The data from measure or test will be treated,and the conclusion will be drawn.Sometimes there are a mass of data need to be treated.Obviously,the way of trating the data quickly and clearly is very necesary.Today,the instrument is more and more compact and the methods to operation are more smarter.But there are some disadvantage.Sometimes we need more special way to some purpose.Some operation are complex too.Sometimes process data isn't on time,which make the time of test long.The test data in the past maybe useful,and how to save data for analysis in the future is a matter we will deal with.In this disseration the author researched the testing of GSM mobile telephone of the wireless instrument test and carried out it. The work that I shoud do is acquire the testing content,standard and method of test of the GSM mobile telephone ,then write the driver program of the CMU200.First acquaint the communication system of GSM;Second introuced and analysized the technology of the software and hardware of control the programmable instrument,which include IEEE 488(GPIB) standard bus,SCPI(Standard Commands for Programmable) and VISA(Virtual Instrument System Architecture);Third reaserach the technology of software, It employs Visual C++6.0 as application development platform because of its powerful function,universality and programming and employs COM module because of its characteristic,superiority;The last ascertain the testing item and its standard,mehtod through searching the principle of GSM mobile and its testing criterion and select the programble instrment for testing according to the mobile telephone demands,which include CMU200(Universal Radio Communication Tester),E4445A(Spectrum analyzer),E4438C(signal generator),all of this build the platform of testing.I realize the automatic testing of GSM mobile telephone by using COM module and VISA,SCPI... |
