About
The Model RDM207 Digital RF Receiver provides unparalleled performance, similar to the Model 4426 range-quality Digital RF Receiver product line. It includes optional RF link and noise mitigation improvements such as Viterbi Decoders/Bit Syncs, Adaptive Equalization (AEQ) to mitigate multipath distortion, and Low Density Parity Check (LDPC) coding to improve link margin while using less bandwidth. The unit operates up to 40 Mbps and is capable of supporting aircraft flight-testing. Recent updates allow for acquiring and processing IRIG106 Chapter 7 data streams, outputting the resulting data packets to Ethernet for downstream processing. 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 offers a compact, cost-competitive, and flexible solution for a wide variety of communications link scenarios. It processes 3 RF Bands: S Band (2185 MHz to 2485 MHz), Upper L Band (1700 MHz to 1850 MHz), and Lower L Band (1427 MHz to 1545 MHz). Additional RF bands are available, including IF (1KHz to 180MHz), P-Band (100 MHz to 1100 MHz), and C-Band, with multi-band options also offered. The demodulation and baseband bit synchronization processes are entirely performed in the digital domain. Signal acquisition is achieved by scanning the IF within a programmed acquisition band centered about the selected Carrier frequency, with PM/PSK waveforms additionally scanned for acquisition at subcarrier frequencies. Once acquired, synchronized signal tracking ensures continuous validation of the lock state. A variety of optional FEC decoders are available, and two fully programmable frame synchronizers (pattern detection) are provided with the bit synchronizer option. Bit Synchronizer data is output via TTL and RS-422 outputs. The unit supports an optional Ethernet output interface for transporting frame-synchronized, byte-aligned data, with UDP/IP transport provided for raw data. IRIG-106 Chapter 10 compatible output is also available, and an encapsulated data and data-quality output may be included to support GDP and RCC Best Source Selector products.
