at the socket (especially when a lot of channels are being transmitted).
FM e DAB
The FM and DAB signal levels should be at least 10dB lower than the overall input power of the
TV signal.
SAT
1. Input signal level: 69 86 dBµV
The input transponder level to the OPT-TX 15x0 must be between 69 and 86 dBµV for the ACG
(automatic gain control) to function correctly.
2. Band flatness: 4dB
The transponders should be equalised within the same polarity so that the maximum difference
in level between the transponders transmitting through the fibre is 4dB, to ensure the receiver is
able to receive correctly.
5. TYPICAL INSTALLATION EXAMPLES
Some example diagrams are available at the end of the manual and on the website www.fracarro.
