SAT
The typical SAT signal output level on the OEC 44 output is:
• If the sum of all Transponders have an total optical level of -14 dBm at the receiver input,
the result for each channel is 59 dB μ V at the output of the receiver (at 21 dB of optical
attenuation and when 120 transponders are used).
• If the sum of all Transponders have a total optical level of -8 dBm at the receiver input, the
result for each channel is 71 dB μ V at the output of the receiver (at 15 dB of optical attenu-
ation and when 120 transponders are used).
The typical SAT signal output level on the OEC 40 output is:
• Transponders with an optical level of -14 dBm at the receiver input have a level of 67 dB
μ V
at the output of the receiver (at 21 dB of optical attenuation and when 120 transponders
are used).
• Transponders with an optical level of -8 dBm at the receiver input have a level of 79 dB μ V
at the output of the receiver (at 15 dB of optical attenuation and when 120 transponders
are used).
• These levels are guidelines in an ideal scenario, assuming that all TV channels at the
input are of the same level and no consideration has been taken of any possible frequency
responses. In more speci
fi
c indvidual cases the output level would need to be measured.
FM and DAB+
The FM and DAB+ signal levels will be lowered by at least 10 dB in relation to the digital TV
signal.
Note: The signal level on the sockets must have the desired values as per EN 60728-
1 standard (stereo FM: 50-70 dB
μ V, DVB-T: 45-74 dB μ V, SAT: 47-77 dB μ V digital
Cable TV: 47-77 dB μ V, DAB +: 28-94 dB μ V (Band III)). In certain cases, the RF
output signal from the receiver or, if possible, the optical input signal must be attenu-
ated by the passive components, such as an optical attenuator.

Information about the output levels of the OEC 40 or OEC 44 TV signal: These levels are
guidelines in an ideal scenario, assuming that all digital TV channels at the input are of the
same level and no consideration has been taken of any possible frequency responses. In
more speci
fi
c individual cases the digital output level would need to be measured.
