There are three ways you can use this control:  

•  Type the IF bandwidth directly into the edit box, in Hz (type in a number 

from 1 to 15000, followed by pressing Enter). 

•  Use the small up/down cursor keys to adjust the 

frequency by 1 Hz steps. 

•  Use the small slider located between the up/down 

cursor keys and move it up or down. This is quite a 
fast and convenient method.  

Another very convenient method is to adjust the IF bandwidth graphically on 
the real-time spectrum display, by dragging the red line bordering the shaded 
area representing the IF filter bandwidth: 
 

 

This method makes it possible to adjust the bandwidth accurately to fit the 
actual bandwidth of the received signal, obtain the best signal-to-noise ratio 
and minimize interference from adjacent channels.
