Advantest R3671 Signal Analyzers

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 R3671 and R3681 are one of these new measuring

instruments for this new era of test and measurement

requirements. The R3671 and R3681 are high performance

signal analyzers. Employing our unique RF technology,

the R3671 and R3681 achieve 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 R3671 and R3681 also

have unique noise correction functions that enhances

their dynamic range (–84 dBc [typical]) for W-CDMA

adjacent leakage power (ACLP) measurements.

The R3671 and R3681 come standard with broadband

modulation analysis functions (bandwidth 25 MHz) as

well as RF measurement functions. By adding the

dedicated signal analysis options for the respective

communication systems to the R3671/3681, you can

expand the functionality of transmitter testers.

Furthermore, with an optional RF signal generator

that supports digital modulation, the R3671 and R3681

provide ease of implementation of the optimum testing

systems for evaluating high-frequency devices.
