Notes:
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
