Before starting any Auto DF process, the part of the spectrum occupied by the suspicious transmitter must be determined. Therefore, you should add a RT Spectrum task with a Spectrum and Spectrogram view. Here, you can also figure out parameters like center frequency, bandwidth, frequency behavior and pulse/pause length of the signal of interest.
The occupied bandwidth Occ. BW and the center frequency Fcent of the signal under investigation can conveniently be measured with the SignalShark using the Occ. BW spectrum marker function.
Go to next step.
