  2. 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

    論文中首先了解了gsm通信系統及其關鍵技術;再者研究分析了可編程儀器控制的軟硬體技術,包括ieee488 ( gpib )標準總線、 scpi ( standardcommandsforprogrammableinstruments可編程儀器標準命令)和visa ( virtualinstrumentsystemarchitecture虛擬儀器軟體架構)為對可編程儀器進行驅動編程打下基礎;第三步研究了軟體實現技術,對組件的優勢和com的特點進行了分析確定採用com組件技術來完成驅動模塊;最後根據移動臺測試要求選擇可編程測量儀器cmu200綜測儀、 e4445a頻譜儀、 e4438c信號源和一臺測量控制計算機搭建起了測試平臺,研讀可編程儀器cmu200綜測儀的scpi命令和visa (虛擬儀器軟體架構) ,根據gsm移動臺測試方法在vc開發平臺下採用com組件形式完成對cmu200的驅動編程從而實現對gsm移動臺的自動測試。
