Interface Configuration and Interpretation
MTM400 MPEG Transport Stream Monitor User Manual 3-109
QPSK (L-Band)
The QPSK (L-Band) Interface option allows you to connect to QPSK equipment
operating in the L-Band (950 MHz to 2150 MHz). It will internally I-Q
demodulate the signal with its on-board AGC control, Viterbi decoder, and FEC
decoder.
The module will tune the full Satellite IF band, which is considerably wider than
the L-Band itself. As LNB support is included, this allows the module to be used
with a stand-alone TVRO dish.
The input to the interface card is looped through to the output connector, allowing
subsequent processing of the input signal.
The L-Band Interface allows you to monitor and/or record the transport streams
from within the L-Band signal.
Bit Error Rate (BER) values are available during operation.
