Modulate the AF level with a frequency 1kHz and deviation of 1.5kHz SG output level for obtaining 12dB / SINAD when injected to each point (Narrow), 3kHz (Wide). Then take from the signal generator through a 470pF coupling capacitor. output when set to -53dBm and obtain the level shown on an AF VTVM Measure the 1st Local level on a RF VTVM. when output has been adjusted to 0.63Vrms with the AF vol.
Measure the audio an AF VTVM and radio frequency on a RF VTVM at high impedance. Set MIC input obtain a moduration factor of 60% with the transmit at center and a modulation frequency of 1kHz.
