Bandwidth of the output signal

 

To transmit the output signal in the channel range of C21 to C69 a bandwidth 

of 8 MHz can be used.

 

In the channel range of C5 to C12 a bandwidth of 

≤ 

7 MHz must be set.

 

If frequency setting is selected you can set the bandwidth dependent on the 
frequency of the adjacent channel.
