Introduction
Designed for government, military, security, surveillance and industrial applications,
WiNRADiO Spectrum Monitor puts advanced radio receiver technology directly on a
personal computer platform to create a high-performance PC-based spectrum surveillance
and monitoring system.
This synergy of advanced radio and computing technology provides the WiNRADiO
Spectrum Monitor with many unique features which are hard to find on the usual stand-alone
communications radio receiver. These features include a rich variety of flexible tuning and
scanning options, versatile memory and database facilities, the ability to digitally process the
received signal, as well as the ability to interact with other programs running on the same
PC. All this is controlled through an innovative user interface, unparalleled in sophistication
and ease of use.
The internal version (WR-3700i-DSP) conserves valuable desk-top space, and avoid the
need for external cables and power supplies. It also have the advantage of not requiring any
additional interface ports, as all communication with the PC is via the internal PC bus. A
dedicated DSP (Digital Signal Processor) is used for real-time audio compression and
playback, and can be expanded to include other real-time signal processing functions tailored
to the user's particular requirements. Multi-channel operation is simple to achieve, as up to
eight WiNRADiO internal receivers can be used simultaneously in the one PC.
The external version (WR-3700e) can be controlled through an RS-232 serial interface, or
the optional plug-and-play PCMCIA interface. The PCMCIA interface allows quick and
simple connection to any laptop PC, providing complete portability for vehicle or field use.
The external versions can be powered by the plug-pack (supplied), or from the optional WR-
PPS battery pack with inbuilt charger. The external model also include a direct discriminator
output, for optimum reception of packet and other digitally modulated signals.
The informative control panel displayed by the WiNRADiO Spectrum Monitor includes a
number of ground-breaking features, designed to empower the user with a multitude of
tuning and scanning capabilities especially tailored for surveillance applications. One of the
most significant features is VisiTune™, a patented feature allowing the operator to
graphically tune within a dynamically-changing spectrum screen representing the actual
situation on the monitored band.
Add to this the fact that WiNRADiO Spectrum Monitor features an automatic task scheduler
which can be programmed for unsupervised operation, search for specific types of signals
and even make decisions based on the specified circumstances, and you will find that
WiNRADiO Spectrum Monitor represents an invaluable tool, making radio surveillance
easier and much more efficient and reliable.
