RDMS™ Rackmount Receivers

Key Features

• Complete Receiver – RF to Bits – a single-box solution that includes downconversion, demodulation, and bit synchronization
• Data Quality Encapsulation (DQE) to bundle Data Quality Metric (DQM) words with payload data, including a sync word to aid BSS time alignment; built-in real-time DQM display
• Best-Channel Selector (BCS) seamlessly selects the best channel (Channel 1, Channel 2, or Pre-Detection Diversity Combiner) based on DQM, which is then used as the combiner data output
• Built-in integrated three-channel spectrum analyzer shows frequency domain view for up to three channels simultaneously
• Multi-Mode diversity combiner supports both Maximal Ratio Combining and Best Source Selection modes and features a revolutionary dynamic time alignment function that increases the allowable time skew between channels by over 1300 nanoseconds—more than 60 bits at high bit rates!
• Built-in playback demodulator IF inputs for each channel, 75 kHz to 20 MHz, or 70 MHz with selectable SAW filter
• Simultaneous RS-422 and TTL for all units
• NEW IRIG 218-20 compatible telemetry transport (TMoIP) via 1000 Base-T Gigabit Ethernet RJ45 port (requires -IP2 option)
• Tuning Range from 200 MHz to 5250 MHz
• Versatile Rack-Mount Enclosures – 1U or 3U 19” rack-mount chassis houses one or two receiver channels covering P, lower L, upper L, full S, C, or multiple bands per channel
• Easy on-site updates of software and firmware may now be installed by the customer on-site via SD card or network
• Best SOQPSK-TG detection in the Industry, yielding improvements of 2 dB or more over the competition’s single-symbol detectors
• True multi-symbol trellis detection all three ARTM modes for optimal demodulation
• 3.5 to 5 dB improvement in PCM/FM performance vs. the best single-symbol demodulators, to within 0.2 dB of the theoretical limit
• Enhanced Modulation Index Tracking* for PCM/FM maintains superior BER performance even if the received signal’s modulation index varies by as much as 500%, a major breakthrough for tracking legacy analog transmitters (*patented)
• Phase Noise Compensation optimizes demodulator performance for use with legacy TM packs and transmitters with excessive phase noise
• Typical noise figure of 3.5 dB bests all other ARTM receivers on the market, hands down
• Synchronizes up to 100 times faster – and maintains sync at lower signal-to-noise ratios – than any other ARTM demodulator
• Spectrum analyzer shows frequency domain view for up to three channels simultaneously
• Automatic AGC zeroing
• Browser-based remote interface
