3.3.6. Adjacent and co channel power
With test modulation representative of normal operational modulation (baud rate and deviation)
shall fall within the limits defined in USA DOD Chapter 5.3.5.2 Emissions mask
Where P is measured power, Pz is Carrier power un-modulated, Fc is Centre frequency, Ft = Test
frequency.
P(dBc)=Pz for Ft from Fc to Fc + - 2.5kHz where Pz=carrier power when un- modulated.
P for Ft =Fc+ - 2.5kHz to Fc + - 12.5kHz, P(dBc)= -7*(Fd-2.5)
P= the lesser of -50dBm or -70dBc for Ft>= Fc+ - 12.5kHz
