2.7.2 ASI Out Secondary
ASI Out Secondary is a female BNC connector with 75O impedance. The port outputs a copy of
the primary transport out.
ASI Out Secondary port can be used to output the transport stream of one SE4000 to the
multiplexer of the SE4000 for MPTS operation. In this configuration, this port is cabled to the Mux
ASI In port of the SE4000 in the MPTS chain.
2.8 Modulator Output to Upconverter
The internal modulator outputs a modulated IF signal, which is connected to an upconverter.
Connections are made through the Tx If Out port. This port is a female BNC connector that
outputs a 70 MHz, 140 MHz, or L-Band DVB-compliant, QPSK, 8PSK, or 16QAM modulated,
FEC encoded IF signal at symbol rates from 1 to 45 Msps.
Before attaching cables from the modulator output to the upconverter,
verify that the modulator power is off until ready to begin satellite
transmissions.
To cable the modulator output to an upconverter, connect the output of the internal modulator
from Tx IF Out to an IF-to-RF upconverter.
There is also an L-Band Monitor port available for direct monitoring connection to an IRD.
