Information about the output levels of the OEC 40 micro or OEC 44 micro 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 specifi c individual cases the digital output level would need
to be measured.
SAT
The typical SAT signal output level on the OEC 44 micro output is:
• If the sum of all transponders has a total optical level of -14 dBm at the receiver input,
the result for each channel is 59 dBμV at the output of the receiver (at 21 dB of optical
attenuation and if 120 transponders are used).
• If the sum of all transponders has a total optical level of -8 dBm at the receiver input,
the result for each channel is 71 dBμV at the output of the receiver (at 15 dB of optical
attenuation and if 120 transponders are used).
The typical SAT signal output level on the OEC 40 micro output is:
• Transponders with an optical level of -14 dBm at the receiver input have a level of
67 dBμV at the output of the receiver (at 21 dB of optical attenuation and if 120 tran-
sponders are used).
• Transponders with an optical level of -8 dBm at the receiver input have a level of
79 dBμV at the output of the receiver (at 15 dB of optical attenuation and if 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 specifi 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.
The signal level on the sockets must have the desired values as per EN
60728-1 standard (stereo FM: 50-70 dBμV, DVB-T: 45-74 dBμV,
SAT: 47-77 dBμV, digital cable TV: 47-77 dBμV, DAB+: 28-94 dBμV (Band
III)). In certain cases, the RF output signal from the receiver or, if possible, the
optical input signal must be attenuated by the passive components, such as
an optical attenuator.
