C. Monitoring functions
C. Monitoring functions
- PA setup function: Module address, PA=ON/OFF, ALC, ATT;
- PA Query function: Working status(on/off,input/output, Revers power, Temperature, VSWR, ATT, ALC, PA Input power,or LNA output power), Alarm(over Temperature,VSWR, PA Fault);
- Over Temperature Alarm: Alarm threshold +85ºC, meanwhile switch off PA, When Temperature lower to +80ºC, switch on PA automatically.
- PA Fault Alarm: Low gain Alarm;
- Amplifier temperature detection: Temperature detection rang including but not limited -40ºC~+85ºC, Detection accuracy<±3ºC;
- PA Forward Power detection: Detect total power, Modulated signal test, detection rang 25dBm~46dBm, Detection accuracy<±2dBm;
- PA Revers Power detection: Detect total power, Modulated signal test detection rang 25dBm~46dBm, Detection accuracy<±2dBm;
