4�  Set the correct 

Diplexer Type

 and set 

Output IDS Control

 to 0 dB�  

5�  Using two-way communication, contact the technician at the next amplifier/node on the upstream� 

Their RF spectrum analyzer test meter should be connected to the test point where the return path 
signals can be seen from a signal generator� Advise the technician at the amplifier being setup to 
adjust the upstream 

tilt

 so that the two CW signals are at the same level�  

 
 
 
 
 
 
 
 
 

6�  Next advise the attenuation level adjustment required to obtain the correct levels for upstream�
