Monitoring Function Description:
| No. | Monitoring function | Description | |
| 1 | query | PA ALARM | When an alarm amplifier failure |
| 2 | SWR ALARM | Amplifier output reflection is too large, VSWR exceeds 3:1, an alarm is generated | |
| 3 | Over temperature alarm | Module internal temperature exceeds 85 ºC, generates an alarm and turn off the amplifier until the temperature returns to below 65 ºC, re-open the amplifier | |
| 4 | Over output power alarm | When the output power exceeds the nominal full power 2dB is an alarm | |
| 5 | Input power detection | Accuracy of ± 1dB | |
| 6 | Reverse power detection | Accuracy of ± 1dB | |
| 7 | output power detection | Detecting the actual output power amplifier,Accuracy of ± 1dB | |
| 8 | Temperature detection | Detection module operating temperature, detection range: -25 ~ +90 ºC, Accuracy of ± 3 ºC | |
| 10 | SWR | Detecting amplifier output port VSWR range of 1.2 ~ 4.0 | |
| 11 | query and set | PA attenuator Set and query | Set and query the value of ATT |
| 12 | PA switching query and set | Query and set the state open tube amplifier | |
