Communication Analyzer : Advantest R3681

With growing data communications traffic, broadband radio communication
systems such as radio-LANs, are being developed that employ various modulation
formats. For example, IMT-2000 and other mobile communication systems
already use multicarrier methods.

Broadband radio signals are already being used in the RF band. To push
this envelope for higher quality data transmissions, researchers and developers
are studying higher frequency/broader band carriers.

In this kind of radio communications environment, new measuring instruments
are needed that are not only more efficient than ever, but also more flexible
to support new test requirements and communication standards.

The R3681 is one of these new measuring instruments for this new era
of test and measurement requirements. The R3681 is a high performance
signal analyzer. Employing its unique RF technology, the R3681 achieves
an Average Display Noise Level of -158 dBm *1), a Third-Order Intercept
Point (TOI) specification of +26 dBm *2), and a signal purity of -122
dBc/Hz *3) to enable measurements over a wide dynamic range.

The R3681 also has a unique noise correction function that enhances its
dynamic range (-84 dBc [typical]) for W-CDMA adjacent leakage power (ACLP)
measurements.

The R3681 supports a standard broadband modulation analysis function
(bandwidth 25 MHz). This functionality enables testing of next-generation
digital radio communication standards. In short, the R3681 with its W-LAN
Signal Analysis Options provides a flexible platform to support next-generation
broadband digital radio communications including IEEE802.11a, HiperLAN/2,
and HiSWANa.
