WAVECOM Monitoring System W-SPECTRA, W-SPEED Manual V1.1.0 Spectrum Editing Tool (W-SPEED)



Note: The computation load of W-SPEED can be quite high when it is displaying an IQ recording into a

two-dimensional sonagram. When possible please turn off the online classification or decoding in W-

SPECTRA: set the Mode to “no-mode”.

Select a Signal and Playback

After W-SPEED finished displaying an IQ recording into a 2-dimensional sonagram the user may navigate

to anywhere of the sonagram, select a signal of his interest by pressing down the left mouse button and

making a stripe with the fix width of 96 kHz. The user can send (stream) the selected signal to W-

SPECTRA for detailed investigation by pressing the “Play” button. At the same time the 96 kHz-wide signal

is output to the speaker for acoustic monitoring. The user may fine tune the frequency position of the se-

lected stripe by adjusting (editing) the value in “Offset” during the streaming of the signal.

Press down the left mouse button, select a 96 kHz signal stripe and send it

(playback) to W-SPECTRA or other Wavecom decoders for detailed investigation.

The selected signal stripe can also be sent to other Wavecom decoders, e.g., W-CODE. The user needs to

define a “Custom Input” with the PXGF format as the following example:

1 2 ... 44 45 46 47 48 49 50 51 52 53 54 ... 291 292
