The IMT-2000 is a third-generation mobile telephone system used to implement increased data transfer speeds, improved voice quality, and international roaming service. The IMT-2000 utilizes a broadband RF digital modulation technique for high-speed data transfer, adopts a multicarrier system to accommodate growth in the number of users, and incorporates other new technologies. In an environment for mobile phone systems, measuring instruments must have higher performance and, at the same time, the flexibility required for developing new communication systems and responding to changes in communication specifications.
The R3477 signal analyzers are high-performance spectrum analyzers that have been developed to meet these requirements. With our proprietary RF technology, the signal analyzers achieve an average display noise level of –158 dBm*1 and third-order intermodulation distortion (TOI) of +26 dBm*2. The wide dynamic range that they can measure is unprecedented. Their noise correction function enables measurement of a wide dynamic range of –86 dBc (representative value), especially useful in measurement of the adjacent channel leakage ratio (ACLR) of 3GPP (W-CDMA). In addition to RF measurement, the R3477 has a broadband modulation analysis function (25 MHz bandwidth) as standard. By adding signal analysis options, each of which is dedicated to a different communication system, the R3477 provide expanded functionality and can be used as a transmitter tester.
*1 Representative value for RBW of 1 Hz, and a frequency of 1 GHz,
when the built-in preamplifier is off
*2 Representative value at a range of 2 GHz to 3.3 GHz
