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.
