Before looking for signals underneath carriers, the parameters of the wanted signal must be specified as shown in Figure: Interference Detection Window

To use carrier-in-carrier detection, the smaller signal needs to be 6 dB (or less) power than the primary (or larger) signal. In the case of more than one interfering signal, there needs to be a > 6 dB power ratio between the larger host carrier and the sum of all underlying interference.

The center frequency of the carrier must be entered as precisely as possible to cancel the carrier correctly from the entire signal. This can be obtained during signal identification Signal Analysis: Basic.

After clicking Detect the calculation starts. It takes some time to remove the wanted carrier from the signal but after that, the results for the following screens are displayed - Received Signal, Remodulated Signal, and the Interfering Signal. See Figure: Signal ID: Advanced Display.

 

You see the remodulated signal after the calculation. The yellow spectrum is the received signal. The green spectrum is the wanted signal. The red spectrum is the interfering signal. See Figure: Remodulated Signal.

If enough samples can be acquired, the interferer is analyzed further as shown in Figure: Interfering Signal.
