Monitoring Functions
- DB9 Monitoring Port.
- PA setup function: Module address(default=0), PA=ON/OFF, ATT;
- PA Query function: Working status(on/off, Revers power, forward power Temperature, VSWR, ATT,), Alarm(over Temperature, over power, VSWR, PA Fault);
- Over Temperature Alarm:Alarm threshold +85ºC, meanwhile switch off PA, When Temperature lower to +65ºC, switch on PA automatically.
- Over power alarm: when output power >Po+2dB
- PA Revers Power detection: Detect total power, Modulated signal test detection rang >20dBm, Detection accuracy<±2dBm;
- Amplifier temperature detection: Temperature detection rang including but not limited 0ºC~+85ºC, Detection accuracy<±3ºC;
- VSWR detection: detection rang including but not limited 1.4~3.0. Detection accuracy: 1.3~1.7@ Load's VSWR=1.5; / 1.5~2.51.3~1.7@ Load's VSWR=2.0;
- PA Forward Power detection: Detect total power, Modulated signal test, detection rang >20dBm, Detection accuracy<±2dBm;
