PCI Card Receiver
The RDM207 (PCI) Single Channel Digital RF/IF Receiver is an integrated solution consisting of an RF Signal Processor, 2 Demodulators, 2 Bit Synchronizers, and 2 Frame Synchronizers (Pattern Detectors) contained on a single slot PCI card. This state-of-the-art module provides a compact, cost-competitive, flexible solution to a wide variety of communications link scenarios.
The Model 4426 processes 3 RF Bands: S Band, 2185 MHz to 2485 MHz; Upper L Band, 1700 MHz to 1850 MHz; Lower L Band 1427 MHz to 1545 MHz. Additional RF bands are available (i.e., IF 1KHz to 180MHz, P-Band 100 MHz to 1100 MHz, C-Band …). Multi-band options are also available.

Antena Tracking Control
The demodulation process, as well as the baseband bit synchronization process, is totally performed in the digital domain. Signal acquisition is performed by scanning the IF within the programmed acquisition band centered about the selected Carrier frequency. PM / PSK waveforms are additionally scanned for acquisition at the subcarrier frequencies. Once signal acquisition is complete, synchronized signal tracking is performed, whereby continuous validation of the lock state is maintained.
A variety of optional FEC decoders are available, and two fully programmable frame synchronizers (pattern detection) are provided with the bit synchronizer. Bit Synchronizer data is output via TTL and RS-422 outputs from the card.

Note: The 70MHz IF IN is analogous to AUX2 on the 4426. The 70MHz IF OUT is after the analog AGC but before the A/D converter. These are
not connected in the standard wiring. The LFA-001 daughter board is required for LFA1, LFA2, IRIGB IN, and IRIGB OUT.
