2.4.2 Transport Stream Input
If no input option module is fitted, connect an MPEG-2 transport stream in
ASI format to one of the two ASI IN connectors (see Annex B, Technical
Specification for details). If the SM66XX/HWO/ASI-SPI option is fitted,
connect an MPEG-2 transport stream, either in ASI format to one of the
four ASI IN connectors, or in SPI format to the SPI IN connector. More
than one transport stream may be fed into the Modulator simultaneously,
but only one is selected as the modulator input. This facility may be used
for input redundancy purposes but automatic switching is not supported.
2.4.3 L-Band Input (Available Only on L-Band Output
Models SM6615 and SM6625)
If required, connect the L-BAND IN connector to the output of an auxiliary
modulator using good quality coaxial cable with a characteristic impedance
of 50 Ω . This facility is useful for combining carriers for transmission via
the same uplink equipment.
2.4.4 Beacon Receiver Input (Available Only on PREKOR™
Models SM6620 and SM6625)
If required, connect the BEACON Rx IN connector to the voltage output of
a beacon receiver using good quality coaxial cable with a characteristic
impedance of 75 Ω . This facility is useful when using PREKOR™ Dynamic
Pre-correction with a satellite that does not have on-board AGC.
