RS485 interface
1) Settings: switch, gain;
2) Query: Module status (including amplifier status, over power alarm, over temperature alarm), amplifier temperature, amplifier ATT value, detected forward power;
3) Overpower alarm: If the power exceeds the maximum output power by+2dB, an alarm will be triggered;
4) Over temperature alarm: It is recommended to set the threshold to+85 ℃. If the temperature exceeds+85 ℃, an alarm should be triggered and the power amplifier should be turned off. When+65 ℃ is reached, the power amplifier should be turned on;
5) Temperature detection of power amplifier: The detection range is required to include but not limited to -25 ℃ to+85 ℃, and the detection accuracy is required to be ± 3 ℃;
6) Forward power detection: The detection range should be greater than 20dB, and the detection accuracy should be less than ± 1dB;
Store in an environment with a humidity of less than 25%, pay attention to dust and anti-static measures, and consider amplifier heat dissipation during installation.
