to the MIC1 line, and set it to:
Frequency: 1 kHz
Level: 300 mV rms
Waveform: Sine wave
Set the audio generator to:
Level: 80 mV rms
Set the audio generator to:
Level: 100 mV rms
• Connect the modulation
analyzer to the antenna
connector through the
attenuator, and set it to:
HPF: OFF
LPF: OFF
De-emphasis: OFF
Detector: (P-P)/2
• Connect the audio generator
to the MIC2 line, and set it to:
Frequency: 1 kHz
Level: 80 mV rms
Waveform: Sine wave
Set the audio generator to:
Level: 100 mV rms
