Spectrum Editing Tool (W-
SPEED)
Main Functionalities
With W-SPECTRA the user can monitor the spectrum online, i.e., the signals in the 96 kHz bandwidth
around the receiver frequency will be analysed, classified and decoded online (in real-time). Signals out-
side this 96 kHz monitoring bandwidth, however, are not lost: the user can make a wideband (2 MHz) IQ
recording with various side information in PXGF format using the wideband media player/recorder.
With the Spectrum Editing tool (W-SPEED) a wideband IQ recording can be displayed in a two-dimensional
sonagram (frequency as the X-axis and time as the Y-axis) with zoom-in and free navigation functions. In-
teresting signals can be selected (marked) and sent to W-SPECTRA or other Wavecom decoders for after-
wards processing.
Spectrum Editing Tool (W-SPEED) displays a recording in a 2 MHz wide sonagram.
The user can select an interesting signal anywhere in the sonagram and send to W-
SPECTRA for detail analysis.
