There are following parameters in a classifier:
Modulation |
Check any number of modulation types or voice using the appropriate check boxes to narrow down the range of recognized signals. |
Continuous Mode |
If continuous classification is desired check this box. Continuous mode can be halted and restarted pressing the Start/Stop Classifier button. If the Continuous Mode check box is left unchecked, each classification must be started manually by pressing the Start/Stop Classifier button. The classifier allows only one classification attempt at a time. During classification attempts the Start/Stop Classifier button is grayed out. |
Refresh List
|
If the Refresh List check box is checked, the list of results will be cleared after each classification attempt. This feature is only available when continuous mode is selected. |
Cycle Mode |
This parameter sets the interval between classification attempts if no signals were classified. Enter a restart cycle length ranging from 4 s to 3600 s. Samples are available from two sources: Samples taken before the classifier was started (select Previous Samples). Samples taken after the classifier was started (select New Samples). |
Sample Time
|
Choose a sample time of 1.6 or 3.2 s. The probability of correct classification of low symbol rate signals increases when the higher sample time is selected. |
OFDM Mode
|
If Full Analysis is selected the modulation format of the OFDM subcarriers is also analyzed. If Partial Analysis is selected, the modulation format of the subcarriers is not analyzed. |
30 Bd CW-Morse Protection |
Checking this box will introduce a feature to prevent the classifier from confusing CW and FSK signals at the edges of the sampled input bandwidth. |
The parameters can be set in the lower right corner of the W-SPECTRA GUI.
Set proper value for the classifier parameters.
