System Architecture

The SCM4000 is designed around a flexible, modular
architecture.

Key features of the SCM4000 are as follows:

•

The SCM4000 can be configured as a Modulator,
Demodulator, or both a Modulator and a Demodulator.

•

Allows simplex or duplex operation, depending upon the
SCM4000 configuration.

•

Optionally available with an MPEG Encoder or Decoder.

•

Provides user control for functional parameters via front
panel controls and an alphanumeric display.

•

Modulation options include QPSK, 16QAM, 32QAM, and
64QAM.

•

Data channel interface types accepted by the SCM4000
include DVB/ASI, RS232/RS485, DS3, E3, T1/E1, 10/100
Ethernet, and SMPTE310M.

Consult your Sales Representative or contact the factory for the
latest information.

The SCM4000 is currently available in the following
configurations:

•

SCM4000 Modulator/Demodulator

•

SCM4000 Modulator

•

SCM4000 Demodulator

•

SCM4000 Modulator/Encoder

•

SCM4000 Demodulator/Decoder.
