All specifications are measured with 0 dB link 74089 at the filter connectors.  
Notes: 
1) 
Frequency range depends on the diplex filters 
2) 
Switchable to 0 dB in manual mode without AGC module installed 
3) 
Can be used as reverse signal injection point 
4) 
Two outputs with optional plug-in splitter or directional coupler 
5) 
CTB/CSO is measured with 6 dB pre-equalizer, EN 50083-3.2. 
6) 
Deviation from nominal level independent of temperature
