The SX-4240 Multi-Mission
Controller is a next generation digital communications
processor providing full-programmable
data
processing and advanced waveform creation, reception, and
processing. The fully digital implementation provides for
the small form/fit
of this
product
while fully satisfying applications requiring ruggedized
packaging and minimum power consumption.
The MMC is implemented in a industry standard 1U 19
inch rack mountable chassis and provides full status and
control capabilities via a standard RS-232 serial port
interface.
Controllable selections include modulation mode, waveform
shaping, data processing/coding functions, ...
Configurable front panel BNC "monitor" ports
allow the SX-4240 to be adapted to a wide variety of applications
requiring access to internal operating signals such as
baseband I/Q waveforms, encoded data/clock signals, auto-baud
detect
signals, and others. The SX-4240 is available in either
a modulator-demodulator (Modem), dual demodulator, or dual
modulator configurations. Modulator configurations can
include either
baseband waveform outputs for use with an external exciter,
or 70/140MHz IF frequencies.
The firmware-intensive implementation of the SX-4240
readily allows accommodation of custom features. A latest
generation
micro-controller combined with a Field Programmable Gate
Array provides for an array of application specific capabilities
via software upgrades only. The unit supports a variety
of modulation formats, including Analog or Digital PM,
BPSK,
QPSK, OQPSK, AQPSK, UQPSK, PM/PSK, FM, FM/FSK, or AM
Waveform Processing. The advanced digital processing
capability of
the SX-4240 allows significant flexibility to meet changing
requirements with simple reprogramming.
Custom features which can be readily supplied include
alternate modulation formats (QAM, trellis-coded modulation,
...),
specific data formatting (frame sync insertion, checksum
processing), and other data coding formats (BCH, Reed-Solomon,
...).
