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 |

| 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 |
