ADCMT日本愛德萬ADVANTEST U3741，U3751頻譜分析儀
Spectrum Analyzer U3741，U3751
Wireless LAN networks, cellular ephones, contactless smart cards, terrestrial digital broadcasts - all of them have become a part of our daily lives, and all of them use high-frequency wireless technology. Diversifying applications and expanding demand for communications devices have exacerbated competition in the market, placing manufacturers under pressure to reduce manufacturing costs. Makers of test and measurement equipment can support increased cost-efficiency by offering faster performance evaluations, thus reducing cost of test and equipment costs. Additionally, demand from device manufacturers has driven a trend for measuring instruments to grow smaller and lighter, so that they may be transported outside the factory, to any location where maintenance and testing work needs to be done. The U3741/U3751 is a portable spectrum analyzer that precisely meets to these demands.
