C. Monitoring Functions
- Module address(default=0, settable);
- PA setup function: PA=ON/OFF, ALC, NAAR;
- PA Query function: Working status(on/off,input/output, Revers power, Temperatuur, VSWR, NAAR, 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 >20dBm, Detection accuracy<±2dBm;
- PA Revers Power detection: Detect total power, Modulated signal test detection rang >20dBm, Detection accuracy<±2dBm;
- PA Input power detection: Detect total power, Modulated signal test detection rang>15dBm, Detection accuracy<±2dBm;
- LNA Setup: NAAR
- LNA Query: NAAR
