Signal classification is done by providing the classifier with a complex sample (IQ) stream of the input signal across the chosen signal bandwidth, for a chosen period of sampling time and at a certain sampling rate. These sample series are examined for the properties of the signals contained within it. The results of the classification are output as a list of classified signal parameters.
Two classification modes are provided: A manual mode and a continuous mode. In manual mode the classifier will make one attempt at classification. In continuous mode, the classifier cyclically classifies signals with a user selectable interval. By default W-SPECTRA runs a classifier in continuous mode.
Depending on the complexity of the signals and the selected classification bandwidth, after a few seconds the classification results are listed in the results window.
Classifier results are displayed one after another in the result window at the lower part of the W-SPECTRA GUI.
