SQT Series

QPSK/8PSK Transmodulator

Features

• Tunes and demodulates QPSK/8PSK satellite signals in DVB-S,
DVB-S2 modulation including DCII FEC used by HITS and others

• Outputs 4 or 8 transponders of SD or HD video in 4 or 8 QAM­RF channels

• Supports user selection of programs to drop, to reduce stream
rate to allow new DVB-S2 high rate transponders to be carried in
256 QAM-RF channels

• Superior QAM performance with unequalized MER at 39dB, high
output levels, and return loss >15dB

• Internal web server allows any PC to access web pages for easy
configuration and simple local or remote operation

• Dense with up to 8 channels in 1RU, low power for low heat and
long life

• ASI input for local content (may be substituted for a satellite
signal, 1 in SQT-400, 2 in SQT-800)
