Advantest R3463 Modulation Spectrum Analyzer
Advantest R3463 Modulation Spectrum Analyzer
Modulation Spectrum Analyzers
Recently, digital mobile communication systems have been the focus of much attention. The R3465/3463 are new modulation spectrum analyzers for testing these new communication systems. In addition to the functions offered by conventional spectrum analyzers, the R3465/3463 have functions for analyzing digital modulated signals such as modulation accuracy and transmission speed. The units have an easy-to-use 'one key solutions' design that anyone can use. There are independent keys for STD mode which automatically sets PHS, PDC and NADC standard parameters and OBW, ACP and harmonic distortion measurement. DDS (Direct Digital Synthesizer) technology enables the R3465/ 3463's excellent basic specifications to fit into a compact size 17 kg. These specifications include a frequency range of 9 kHz to 8 GHz (R3465) or 9 kHz to 3 GHz (R3463), highly stable narrow band sweep and high–speed measuring made possible by the newly–developed high speed settling synthesizer. The R3465/3463 provide total support for digital mobile communication equipment in applications ranging from radio systems development to production line adjustment and testing.

■ High Performance Spectrum Analyzer Functions
The R3465/3463 are high performance spectrum analyzers with ample basic functions for waveform analysis in minute detail. The newly–developed high speed settling synthesizer has greatly improved blanking time during narrow–band sweep (span ≤ 5MHz), providing high speed measurement. The units have a frequency span accuracy of 1% or less, residual FM 3Hz p-p or less /0.1 sec, and drift 20Hz or less (span ≤ 5MHz). The R3465 also enables high frequency measurements with a dynamic range of 90 dBc using a 1.7 GHz (min.) built–in preselector.
