TOKYO, Japan, November 14, 2006 - Advantest Corporation (TSE: 6857, NYSE: ATE), today announced that its new low-cost portable spectrum analyzer, the U3741, suitable for electromagnetic environment analysis and other field applications, as well as wireless communications device and module production lines, has been available since the beginning of November.
Wireless LAN networks, cellular telephones, 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.
Advantest's new U3741 joins the three other models in the company's U3700 series (the 8GHz, 31.GHz, and 43GHz spectrum analyzers). Measuring frequencies in the 9kHz to 3GHz band, it performs at twice the speed of the previous model (the R3131A), and offers a higher level of overall accuracy: +/- 0.8dB at 1GHz, as opposed to +/- 1.5dB. It can also measure transmission power - a function essential to wireless device performance evaluation - rapidly and with a high degree of accuracy, thus contributing significantly to production line efficiency. The product boasts a compact body (1/2 the size of the R3131A) - a design characteristic it shares with the other models in the U3700 series - and a removable external battery that allows for two hours of continuous operation. Its standard configuration includes every interface currently in use. Additionally, an option permitting impedance entry at 75Ω makes the U3741 an optimal tool for electromagnetic environment analyses, including terrestrial digital TV reception problems.
Although this low cost, general-use spectrum analyzer scores higher on every performance criterion than its predecessor, the widely adopted R3131A, Advantest is offering it at an almost identical price - a position certain to be appreciated by manufacturers seeking to reduce equipment costs.
