@ AM SECTION
Measuring methods in confirmity with IEC standard 315
Measurements condition AM - MW: Radio frequency = 1000/999kHz, Audio frequency = 400Hz
LW : Radio frequency = 207kHz, Audio frequency = 400Hz
Reference level = 5mV/m,10mV/m on 500hms
Modulation = 30%
Test Point: MW
TP1=(600)kHz
TP2=(1000)kHz
TP3 = (1400)kHz
LW TP1=
162kHz,
TP2=
207kHz,
TP3=252kHz
