5.3.3.B. Modulation Capability:
Input a standard modulator test signal into the microphone audio. Using the
linear detector, measure the Tx modulation.
5.3.3.B.1 118.000 MHz ______ NLT 70%
126.97 MHz ______ NLT 70%
135.97 MHz ______ NLT 70%
5.3.3.B.2 Carrier Noise Level:
Modulate the carrier with 70% at 1000 Hz.
Noise on the carrier with modulation removed shall be NLT:
118.00 MHz ___ 40dB 126.97 MHz ___ 40dB 135.95 MHz ___ 40dB
5.3.3.B.3 Demodulated Audio Distortion (Optional):
350 Hz = ___ 15% Max 1 kHz = ___ 15% Max 2.5 kHz = ___ 15% Max
(This is an optional test that requires a distortion analyzer).
