Configuring the TDR7 with a Remote Control Device
Configuring the Demodulator
Once you have finished installing your TDR7, you must configure the
demodulator to receive the incoming RF signal. To configure the
demodulator, follow the steps below.
Before you begin, you must have the following information:
1. The incoming signal RF frequency. This frequency may also be
referred to as the satellite downlink frequency. If the frequency is
not in
MHz, convert the frequency to MHz.
2. The local oscillator frequency of your LNB downconverter. This
frequency is typically posted somewhere on the equipment or in
the manufacturer’s documentation. If the frequency is not in
MHz,
convert the frequency to MHz.
3. The transport stream data rate of the incoming RF signal.
4. The Viterbi code rate of the incoming RF signal.
5. The polarization of the incoming RF signal.
In this example, assume that you want to configure the
TDR7 to the
following parameters:
• RF Frequency: 13225 MHz
• LO Frequency: 11300
MHz
• Transport Stream Data Rate: 7000000 bps
• Viterbi Code Rate: 7/8
• Incoming Signal Polarization: Vertical
