Conditions of Measurements on HF Generator
Reception
AM mode: Level - 107 dBm Frequency 1 KHz with 60% of modulation.
FM mode: Level - 107 dBm Frequency 1 KHz with 1,2KHz of deviation.
Connect HF generator to jack antenna
adjusted at ( –107dBm 1KHz 60%),
connect sinad meter to jack EXT speaker
and adjust coils for maximum sensitivity(
≥ 20dB sinad).
Connect HF generator to jack antenna
adjusted at ( –107dBm 1KHz 1,2KHz
Dev),connect sinad meter to jack EXT
speaker and adjust L9 for maximum
sensitivity( ≥ 20dB sinad).
adjusted at ( –67dBm 1KHz 60%) and
adjust RT2 so that the 4th led is lighting.
Connect HF generator to jack antenna
adjusted at ( –47dBm 1KHz 60%) and
adjust RT1 so that the signal is audible .
Connect sinad meter to jack EXT speaker,
adjust the ouput level of HF generator and
adjust RT401 to reach at the opening ASC
a sinad of 17dB±2dB.
