Abstract
Radio dua hala merupakan satu alat telekomunikasi yang terdapat di pasaran sejak dulu lagi dalam bidang telekomunikasi. Beroperasi secara dua hala, radio dua hala digunakan dalam pelbagai bidang seperti ketenteraan, radio amatur, bomba serta banyak lagi bidang komersial. Untuk melaksanakan analisis Radio Frekuensi (RF) terhadap radio dua hala, banyak industi menggunakan kaedah manual di mana manusia terpaksa melakukan pengujian RF dan kaedah ini memakan tenaga serta masa. Thesis ini membincangkan cara untuk menyelesaikan masalah ini. Objektif utama bagi Penghasilan Peralatan Pengujian Automatik(ATE) bagi Radio Frekuensi Tinggi adalah untuk menganalisa keupayaan radio dua hala, melaksanakan pengujian RF berlandaskan TIA603C dan menghasilkan program bagi Peralatan Pengujian Automatik (ATE) untuk melaksanakan analisis tersebut. Untuk menjayakan projek ini, beberapa kaedah telah diaplikasikan dari segi perisian dan perkakasan. NI LabVIEW adalah perisian yang diguna pakai sebagai program ATE. Satu program automasi telah direka menggunakan perisian NI LabVIEW untuk melakukan pengujian ATE bagi radio dua hala selepas melakukan analisis RF berlandaskan standard TIA603. Manakala buat aspek perkakasan, satu kotak kawalan laluan RF telah direka bentuk. Kotak kawalan ini dikawal menggunakan program automasi yang direka dengan NI LabVIEW. Data yang diperoleh telah disusun dalam bentuk jadual. Data yang digunakan bagi perbandingan adalah menggunakan data automasi dan data kaedah manual. Bila dibandingkan, data yang disusun agak sama; membuktikan bahawa proses pengautomasian dalam projek ini berjaya. Di samping itu, masa untuk melakukan analisis RF juga dipendekkan. Kesemua analisis ini telah dilaksanakan mengikut Telecommunication Industry Association (TIA). ________________________________________________________________________________________________________________________ Walkie-talkie is an important telecommunication device that has been for quite a long time in the telecommunication field. Being a duplex mode communication transceiver, it is widely used around the world in variety of field such as military purpose, amateur radio, fire and rescue department along with many other commercial usages. To perform the Radio Frequency (RF) analysis on the radio, many industries still using the outdated manual testing method using man power, consequently spending a lot of effort and investments in the process. This paper discusses the method to overcome this problem. The main objectives of this Development of Automated Testing Equipment For Very High Frequency Radio project are to analyse the performance of a portable walkie-talkie radio, perform radio frequency analysis based on TIA603 standard and develop Automated Testing Equipment (ATE) program to perform the analysis. In order to complete this project, several approach was utelised in term of software and hardware basis. NI LabVIEW software was used as ATE testing development program software as the adoption of software-defined test systems. An automation sequence using NI LabVIEW was developed to perform the ATE testing after researching on the RF analysis aspect based on the mentioned TIA603 standard aspect. Wherelse the hardware mentioned was developing a RF path switching control box. This control box was controlled by the developed automation program using the NI LabVIEW software. The outcome obtained through this project was further compiled in table form. The data used for comparison purpose were the test outcome using the manual method with the automation method. These data when compared are almost similar; thus proves that the automating process of the manual method was a success. Besides that, the time to perform the RF analysis also was managed to shortened; resulting in a shorter testing duration. All this aspects was measured and analysed in accordance with the Telecommunication Industry Association (TIA) in this project.
