Operating levels of the forward path:
Max input level
Max output level
Technical characteristics: see label inside of the product.
Working output level:
In order to determine the max output level according to the channel loading the
following formula can be applied:
WOlevel = RefOlevel – FCorrection
With: WOlevel: maximum Working output level to guaranteed 54dB of IM3 protection.
RefOlevel: Output level specified
FCorrection: Correction Factor according to channel loading
Nb of Channels*
Correction factor
(*) The channel loading is assumed by the number of analogue channels in each band
UHF and VHF for the split amplifier and by the total of analogue channels in UHF
and VHF for the broad band amplifier. The loading of digital channel is assumed as
negligible due to the power level difference of at least 10 dB below the analogue.
