R3465/3463
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.
■ Automatic Setting of Standard Parameters
The cumbersome parameter settings required for measuring
digital radio system standards such as PHS, PDC and NADC
(GSM, DCS1800, DCS1900, DECT and CDMA optional), are set
automatically for each measurement item.
See the options table for each standard measurement.
■ Dual Mode Analysis
As well as CW mode, for conventional spectrum analysis, the
R3465/3463 have a TRANSIENT mode for digital transmission
analysis of modulation accuracy and transmission speed. The
unit also employ the FAST function, a newly–developed measuring algorithm which greatly reduces the measurement time.
■ Menu Operation
The R3465/3463 have a 'one key solutions' design for simple
operation. Basic measurement and analysis functions can be
easily started by selecting the desired measurement item.
■ 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
5MHz), providing high speed measurement.
frequency span accuracy of 1% or less, residual FM 3Hz
less /0.1 sec, and drift 20Hz or less (span ≤ 5MHz). The R3465
also enables high frequency measurements with a dynamic
