Embedded controller allows direct access to ATM
The Interphase 4531, available in the UK from Crellon Microsystems, allows system integrators to access the ATM backbone without requiring an external CSU/DSU.
Embedded motherboard configured for connectivity
The PATX3070 Pentium-class motherboard, now available from Crellon Microsystems, combines AGP graphics capability with a range of powerful interfaces.
The RCB-4000 offers a compact receiving system that combines dual high performance telemetry RF receivers, a dynamic predetection diversity combiner, a DSP based multimode demodulator with state of the art FIR IF and video filters plus a high performance programmable bit synchroniser, all within a single, small, lightweight and rugged design 5.25in-high rack-mounted chassis and is fully compatible with ARTM Tier-II phase noise specifications.
The RCB-4000 features excellent adjacent channel rejection by employing multiple state-of-the-art SAW first IF bandwidth filters in combination with highly selectable FIR second IF filters.
These multiple, user selected second IF FIR filters are preprogrammed with bandwidths available from 50kHz to 30MHz for each channel.
This unit is provided as standard with all IRIG filters however other frequencies can be programmed without replacing hardware.
Further features include an onboard optimal ratio combiner which uses a high speed AGC/AM driven control signal enabling efficient handling of fast/deep fades (50kHz combiner break frequency), a multimode demodulator with FM, PM, QPSK, and OQPSK modes as standard and featuring the new trellis FM mode technology, FQPSK (Feher patented FPQSK technologies), and S0QPSK as options, ease of use front panel and remote control via RS232, Ethernet and IEEE488 and comes complete with Windows application software, providing remote operation of front panel controls via the Ethernet interface.
The RCB-4000 is equipped with AM and AGC outputs that make it compatible with both conventional autotracking antenna systems and linear predictor antenna tracking systems commonly found in phased array antennas.
