Software Highlights (cont.)
EXPLOIT VISUAL DATA FOR INFORMATION INTELLIGENCE
SystemFlow includes a viewer for signal monitoring in both
frequency and time domains. To view live or recorded data, this
integrated signal viewer provides spectrogram and waterfall
displays, a virtual oscilloscope and a spectrum analyzer for
signal review and analysis. Enhanced features include frequency
zoom, panning modes, averaging to reduce and control noise,
dual annotated cursors to mark, measure and amplify signals
of interest and many more essential functions (see Figure 3.).
EXTRACT SIGNALS OF INTEREST
The SystemFlow Signal Viewer also provides signal analysis
tools for analyzing a recorded data file. This tool allows users
to quickly and easily scan through a recording to find signals of
interest. Operators can use the built-in data extraction utility
to copy interesting sections of the recording to a new file.
This allows operators to turn a large recording session into
one or more small files of interesting data while preserving
time stamp information during the extraction process.
ADD USER-SPECIFIED PROCESSING TECHNIQUES
WITH FPGA FUNCTIONALITY
ArchiTek™ FPGA development suite allows design
engineers to add custom IP to a number of Mercury 's
Talon recording systems. FPGA IP can be installed in the
recorder to provide real-time, on-the-fly digital signal
processing during the data acquisition process, greatly
reducing the time associated with post-processing
recorded data. ArchiTek provides a simple development
environment so engineers can add FPGA IP such as threshold
detection, spectral filtering, digital down conversion,
demodulation and other digital signal processing tasks.
AUTOMATICALLY DETECT SMALL SIGNALS
ACROSS A VERY LARGE SPECTRUM
Sentinel™ software takes the Talon recorder product line to the
next level of integration by automating signal monitoring and
detection. The user specifies a start and stop frequency across
span of interest, and the desired signal strength threshold to
trigger a recording. The user then selects the bandwidth of
adjacent frequency bands for stepping sequentially across
the span. If the strength of any signal within a band exceeds
the threshold, the stepping stops and the recording of that
band is automatically started. This is extremely valuable for
remote unattended monitoring and recording applications.
Figure 3: The built-in Signal Viewer displays both time and frequency domain
representations of the captured signal before, during and after recording.
