TechniSat Line Amplifier 17Z - Handbuch (Seite 22)

7 Technical data accessories to GigaSystem 17 / X, guaranteed
parameters
1) All other trunk lines have a signal
2) Related to broadband cable signal in BC grid (36 TV signals, 14 FM radio programmes), CTB (72 dB)
/ CSO (69 dB), with terrestrial reception individual channels are usually stronger, this is acceptable as
long as they remain <90 dBμV.
3) In accordance with EN 50083-3: IMA3 35 dB
