Power amplifier status: 

ON: 

 The current signal is connected to the power amplifier unit. 

OFF:

 Indicates that bypass mode is selected, the power amplifier is switched out of 

circuit. 

Indicates that the power amplifier is operational. 

RX 

Indicates that the unit is in receive mode. 

TX 

Indicates that the unit is in the transmit mode. 

 

Input power value: 

Displays the power input value to the XPA125B in Watts. 

 

Current working band status: 

Displays the current working band, and whether automatic or manual mode 
is selected. 
The figure above shows the 6 meter band. 

(9) 

Output power value: 

Displays the output power being delivered by the XPA125B in Watts. 
Automatic antenna tuner unit (ATU) status: 

(10) 

Displays the status of the automatic antenna tuner. 

OFF: 

  Indicates that the XPA125B is not connected to the automatic antenna tuner 

unit. (BYPS) 

ON:  

  Indicates that the XPA125B is connected to the automatic antenna tuner unit. 

(IN USE) 
 
When tuning is successful,

 

The output standing wave value will display stably. 

If tuning fails,

 

The output standing wave value will flash.
