Introduction
W-SPECTRA
In the modern data communication and signal intelligence the user requires more and more a complete
automatic system which monitors certain frequency bands, fullfills the following main tasks:
 It controls the receiver directly, set the receiver frequency, demodulator and demodulator band-
width, etc.
 It classifies and decodes signals automatically.
 It records the results of classification and decoding into a database.
 It records the spectrum in a wide bandwidth, so that the user can analyse the whole spectrum af-
terwards.
W-SPECTRA is exactly such a system to meet these major demands. W-SPECTRA provides:
 Comprehensive online (real-time) monitoring functions, running through the entire radio spec-
trum from ELF to SHF
 Intuitive graphical user interface: its main operation tab covers all online monitoring activities
 Built-in bi-directional control of receivers (WiNRADiO G3xDDC)
 Three monitoring modes: Direct Mode, Memory Scan and Frequency Search
 More than 220 mode decoders and protocols over HF/VHF/UHF/SHF
 Wideband (2 MHz) and narrowband (96 kHz) FFT and sonagram displays
 Wideband (2 MHz) and narrowband (96 kHz) signal recording in baseband (IQ) and signal play-
back
 Signal recording is made with various important side information (meta-data) on-the-fly, such as
the receiver frequency, bandwidth and timestamp for complete investigation of the whole spec-
trum after the online monitoring
 Automatic demodulation and decoding of known signals to the content level
 Automatic search, classification and code check of signals over a user-defined frequency band and
certain search strategy
 Automatic or manual capturing of results into a database
 Display of classification and decoding results in a separate window
 Classification and decoding results can be saved into files as well
 User configurable database template
 Database in XML format, providing easy processing by third-party applications
 Integrity check of the database
 Wideband spectrum editing: display a wideband IQ recording in a 2-dimensional sonagram,
zoom-in view of the sonagram and cut out a signal anywhere (in time and frequency domains)
from a wideband IQ recording for classification and decoding afterwards.
A typical configuration of an automatic spectrum monitoring system with W-SPECTRA can look like the fol-
