Product Description
Model CM3014 is a quad QPSK-to-QAM transmodulator station designed for such application that combination with local CATV signal is necessary.
The device accepts up to four DVB-S/S2 satellite inputs, and completes QPSK demodulation + QAM modulation. Accordingly, CM3014 uses maximum 4 QAM TPS. A 4-way combiner embedded in CM3014 mixes RF signals from QAM TPS as one. The Mixed RF has a tuning range of 0~5dB in level. However, each QAM TP's RF level could be adjusted independently too.
A 2-way combiner is built after the 4-way combiner. The 2-way combiner mixes local CATV RF (47~862MHz) with QAM signal (470~862MHz). The overall RF output of CM3014 has a tuning range of 0~32dB in level.
CM3014 is built in Aluminum housing with four oval holes for wall mounting. The RS-232 port allows connection to PC to configure parameters, making installation and maintenance convenient and easy.
Accepts up to 4 DVB-S/S2 inputs.
QAM RF output frequency adjustable (470~862MHz, 8MHz per band).
QAM RF output level can be tuned together or independently.
Embedded with a 2-way combiner to mix with local CATV RF.
Overall RF output has a tuning range of 0~32dB in level.
RS232 port for parameter configuration.
Aluminum housing for wall mounting.
