SPECIFICATIONS
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 QAM-
RF 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)
