Impact of VSWR Network Analyzer and Advanced Program Interface on User Performance

Abstract

The present study investigates the frequency measurement process of mobile phone antennas utilizing a VSWR (Voltage Standing Wave Ratio) network analyzer, and the impact of an automatic measurement program interface developed in this process on user performance. Prior to the study, the antennas of the phones were measured manually with the support of the network analyzer, and the results were calculated by the test engineer. The development of a program in C# has enabled the automation of the measurement process, enhanced measurement accuracy, and improved user interaction. In this study, the structural features of mobile antennas are examined, along with their importance, the measurement principles of the network analyzer device, and the effects of program interface design on performance. Consequently, the development of a program and test jig has led to the automation and acceleration of the testing process for mobile phone antennas. The configuration files were compiled using data obtained from 600 tests conducted on each phone model produced. The improved interface design increased operator efficiency, allowing more time for high-value tasks. Consequently, the developed software and test jig automated and accelerated the testing process for mobile phone antennas. With the improved system, the analysis and sorting process, which previously took one hour, was reduced to 20 seconds, resulting in an annual profit of 25,000$.
