Adjacent channel offset 
1 ~ 2 

The frequency distance 
between the adjacent 
channels and main 
channel. 
Range: 1 
Between 0Hz~3GHz   
(0Hz excepted) 

OCBW% 

The ratio of occupied 
bandwidth to the 
amount of power 
consumed.  
Range: 0% to 100%, 0.1% 
resolution. 

ACPR 

 

Description 

Adjacent channel power refers to the amount of 
power leaked to the adjacent channel from the 
main channel. This measurement is a ratio of 
the main channel power to power in the 
adjacent channel.
