Factory default:
½ Viterbi
Sets the FEC code rate i.e. the number of bits input to the Forward Error
Description:
Correction encoder relative to the number output, thereby determining
the level of information redundancy and protection of the data stream
against errors. (In DVB-S2 IP multistreaming mode then there will be one
FEC rate screen shown for each stream, as each can be set
independently.) Not all FEC rates are available for all modulations
and FEC schemes – please check the 'Table of Normal Operation
with respect to FEC Mode, FEC Rate and Modulation Scheme'
shown in the Edit-Tx-FEC-Inner Menu section.
Note: Paradise TPC rate 7/8 was developed to give better performance than Viterbi rate 7/8ths (by about 1dB) with a
similar latency. However, if you require interoperability with other manufacturers' equipment or a better coding gain, then
you should select de facto TPC rate 7/8.
