TOKYO, Japan, March 27th, 2002 --
Advantest Corporation (TSE: 6857, NYSE: ATE) has
announced today that it has begun sales of its R4870
Bluetooth Tester, which will help manufacturers ensure
that their Bluetooth-enabled products and devices
conform with the wireless technology's global
specifications. Targeted for use both within R&D
laboratories (pre-qualification testing) and
manufacturing lines, the R4870 is the first Bluetooth
conformance test system to combine in a single unit the
ability to test both a product's radio frequency
characteristics and its interoperability with other
Bluetooth-enabled products.
Advantest will
display the R4870 at Bluetooth Expo 2002, Asia's largest
Bluetooth exhibition to be held from April 17th to the
19th at the Makuhari Messe convention center in Chiba
prefecture, Japan. | |

Test
Equipment Crucial Driver for Bluetooth
Development
|
|
In
recent years, the Bluetooth specification has enjoyed
enthusiastic support from companies around the world thanks to
its potential to provide a low-cost solution for establishing
ad hoc, short-range wireless networks between a vast range of
consumer electronics such as mobile phones, PCs, and PDAs. In
order for Bluetooth to live up to its potential, however,
manufacturers must first ensure that their Bluetooth-enabled
products can actually provide the high level of
interoperability that lies at the heart of the Bluetooth
concept. Access to high-performance radio frequency and
interoperability test equipment that can both increase
manufacturing productivity while lowering test costs has thus
become a key driver behind quickly bringing new Bluetooth
products to market.

R4870's Wealth of Testing Functions Ensures High
Cost-Effectiveness
|
|
To
help manufacturers meet the challenges of Bluetooth
conformance testing, Advantest has released the R4870-a
dedicated Bluetooth tester based on the company's proprietary
Wizard of Module Test (WMT) architecture. The R4870 is the
first Bluetooth conformance tester to offer the ability to
perform both radio frequency and interoperability testing
(communication test) in accordance with the Bluetooth Special
Interest Group's (SIG) specifications. Designed to serve as a
stand-alone solution to manufacturing line and pre-shipment
testing, the R4870 can also be combined with other testing
equipment to provide pre-qualification testing of product
prototypes.
For testing of the Bluetooth radio layer,
the R4870 is capable of performing tests on output power,
modulation characteristics, initial carrier frequency
tolerance, and sensitivity as defined by the SIG. The R4870
also comes with a number of additional functions such as the
ability to automatically startup testing of Bluetooth modules
via its embedded Host Control Interface (HCI) and the ability
to perform testing using a "dirty" transmitter signal (an
irregularly modulated signal used to test a product's
modulation characteristics).
Also, because the R4870
has built-in protocols for the execution of Blue Unit test
cases (test programs used to ensure a minimum level of
interoperability), manufacturers will be able to perform the
SIG's communication tests without having to procure separate
interoperability test equipment. To help shorten test
times-and thus reduce manufacturing costs-the R4870 comes with
a unique high-speed testing mode function for manufacturing
line and pre-shipment testing. And, to ensure high usability,
the R4870 incorporates a 12-inch color touch-panel display
that will enable test engineers to quickly alter their testing
setup.
Furthermore, when used in conjunction with
other test equipment such as spectrum analyzers and pattern
generators*, the R4870 is also capable of testing all the
radio frequency requirements specified by the SIG.
Manufacturers will thus have the power to perform
pre-qualification testing and accelerate their certification
process by a Bluetooth Qualification Test Facility (BQTF).
