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 Advantest R3477 Signal Analyzer is a high-performance spectrum analyzer that have been developed to meet these requirements. With Advantest RF technology, the signal analyzer achieves an average display noise level of –158 dBm1 and third-order intermodulation distortion (TOI) of +26 dBm2. The wide dynamic range that it can measure is unprecedented. The 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 3477 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 3477 provides expanded functionality and can be used as a transmitter tester.
