A B S T R A C T The present invention relates to a method of evaluating the impact of an electromagnetic environment 5 on a radio receiver (10) that includes a squelch device (11) and sound emission means (16) . The total signal received by an antenna (5) is passed to an automatic acquisition system (30). For each channel, a filtered signal transmitted in said channel is extracted from said 10 total signal, the filtered signal is transposed into a transposed signal having the same amplitude as the filtered signal, the transposed signal is passed to the radio receiver, the state of said squelch device as a result of receiving the transposed signal is determined, 15 and for each scanned channel the state of said squelch device (11) is stored in memory. |
