TOKYO, Japan, April 17, 2003 -
Advantest Corporation (TSE: 6857, NYSE: ATE) introduced
today its new, high-end R3681 Signal Analyzer for use in
research on mobile communications, satellite
communications, microwave repeaters, and other such
technologies that utilize multiple, narrowly spaced
frequencies and require precise power management. In
addition, Advantest has also released a software option
for the R3681 that will allow users to perform
modulation analysis according to the various emerging
standards for next-generation wireless LANs (WLAN).
With consumers rapidly signing up for cell phone
and WLAN Internet access and manufacturers continuing to
develop the components, devices, and base stations
necessary for next-generation wireless communications,
the foundation for a constantly networked society is
rapidly taking shape. To provide faster data rates for
animation, video streaming, and other such
data-intensive content, newer communication technologies
both increase the number of channels within a given
bandwidth and expand into higher frequencies-trends that
can also be seen in older technologies such as satellite
communications and microwave repeaters. These
innovations, however, have also made it increasingly
important for manufacturers to receive high-precision
signal analyzers that allow them to minimize
transmission errors and crosstalk.
With an
average noise level of -156dBm and 26dBm (typical value)
third-order intermodulation distortion, the new R3681
Signal Analyzer possesses a best-in-class dynamic range
and sets a new standard for high-end signal analyzers
geared at design stage testing of wireless devices. When
installed with its simultaneously released software
option, the R3681 can also be used to perform OFDM
(Orthogonal Frequency Division Multiplexing) modulation
analysis according to the world's three emerging WLAN
standards: IEEE 802.11a (US), HiSWANa (Japan), and
HiperLAN2 (Europe). Also, by simply changing its OFDM
modulation parameters, the R3681 can also be used to
analyze signals that have yet to be specified by such
standards.
The R3681 employs Advantest's
proprietary Wizard of Module Test architecture, a
modular platform that allows users to quickly
reconfigure their test instrument to suit their changing
needs. Thus, by adding future modules such as signal and
arbitrary waveform generators, using minimum additional
investment, users will be able to construct the most
efficient test instrument for their target application.
Furthermore, the R3681 also comes equipped with an
analysis bandwidth of over 140MHz, which will allow
users to upgrade the R3681 to perform research on the
next generation of broadband wireless technologies by
simply adding future options.
The R3681 features
a large, 12-inch, touch-screen display that can be split
into four separate windows, each window being the same
size as the displays used in present-day spectrum
analyzers. This enables the user to observe a signal
from four different aspects without having to constantly
switch back and forth between different screens.
Moreover, the touch-screen display also makes the R3681
easy to operate by allowing the user to interact
directly with the
instrument.
