3.4.5 Decoder with RF Output
3.4.5.1 Dual Decoder with RF Modulation
For modules with built-in modulation and RF up-conversion, the RF up-converted
output is a female F-connector, one for each TV channel. The upper connector is
channel A while the lower connector is channel B.
The standard version of the RF output covers the complete band from 47 MHz to 862
MHz. Alternatively the RF modules can be delivered with a low spurious option. For
the low spurious option, the frequency range is divided into the following three bands:
Low Band 47 MHz to 340 MHz
Medium Band 330 MHz to 620 MHz
High Band 500 MHz to 862 MHz
For the low spurious option, each output is marked with frequency band. The
available frequency range is reflected in the GUI by only presenting legal values.
The RF output can be muted by an eternal system by applying 5 V to the mute
connector. Channel A and channel B can be muted individually. The dual decoder with
RF modulation is 2 slots wide.
3.4.5.2 Dual Decoder with RF Modulation and Stereo Sound
The RF output is the same as in for section 3.4.5.1 with the addition of a NICAM
stereo sound carrier or A2 stereo modulation.
