The first thing to check is whether the fault is somewhere in the aerial circuit, the power source, the handset, or inside the VHF system itself.
  • Page 134 VHF 1000 / VHF 1100 Service Connect an RF signal generator to the aerial input, and adjust the signal level to -30 dBm (EMF: 83 dB/µV). Modulate the carrier frequency with 1 kHz to a peak frequency deviation of 3 kHz. Connect the AF_out (receiver output) signal from the test box to the audio analyser, and measure the audio frequency distortion.
