Engineered to Endure
Test Equipment
Terrasat recommends the equipment or its equivalent listed in
for
installation and system alignment.
Ensure that the Tx output power is disabled to prevent accidental transmission
interference with adjacent satellites or transponders before attempting to align or
performing any other operation involving the ODU. Before attempting any system
change, carefully evaluate the possible effects of the transmitted signal.
Setting the Tx Frequencies
All transmit and receive frequencies are set by using the modem. For a direct
connection to an L-band modem, follow the manufacturer’s instructions on setting the
transmit and receive frequencies.
Tx Power Alignment
Transmit L-band Input Adjustment with Modem or Converter
To set the power level of the modulator output:
1. Use a spectrum analyzer to measure the power level of the L-band signal at the
output of the coaxial cable that connects to the Tx 1+1 interface module at J2 (Tx
L-band).
