Rx Audio test
1. Set RX mode CH7.
2. Set SG RF level to –50dBm with 1.5KHz deviation
1KHz modulation Signal.
3. Adjust L517 to provide minimum distortion & max
output level at TP117.
4. Rotate the volume switch to the position, which give a
Max audio output at TP117.
5. Check Max audio output level >1500mV.
6. Check Rx current <150mA.
7. Check the 1KHz distortion <= 5%.
8. Set SG RF level to –119dBm with 1.5kHz deviation at
1KHz audio frequency.
a). Check SINAD sensitivity <= -119dBm.
@12dB SINAD at TP117.
