Notes to the characteristics:
1. Intermodulation Suppression: measured with: 91% pilot signal; fm = 10kHz or 13kHz.
2. Traffic Radio (V.F.) Suppression: measured with: 91% stereo signal; 9% pilot signal; fm=1kHz; 5% subcarrier (f = 57kHz,
fm = 23Hz AM, m = 60%)
3. SCA ( Subsidiary Communications Authorization ) measured with: 81% mono signal; 9% pilot signal; fm = 1kHz; 10%SCA - subcarrier
( fs = 67kHz, unmodulated ).
4. ACI ( Adjacent Channel Interference ) measured with: 90% mono signal; 9% pilot signal; fm =1kHz; 1% spurious signal
( fs = 110kHz or 186kHz, unmodulated).
5. By Design/Characterization but functionally guaranteed through dedicated test mode structure
