RDMS™ Rackmount Receivers

Quasonix RDMS™ 1U rackmount receiver

The Final Word on Data Integrity

The highest performing telemetry receiver on the market is available in an elegant, compact 1U rack mount package and a 3U touchscreen package with dual, 7-inch full color touchscreens. Configurations include one channel, two channels, or two channels plus combiner; an integrated three-channel spectrum analyzer; automatic AGC zeroing; PCM deframing (header detection/extraction, Sub-Frame ID (SFID) checking/extraction); built-in playback demodulator; combiner IF output; simultaneous TTL and RS-422 outputs; contiguous frequency tuning; adaptive equalizer; and decoding for SOQPSK Space Time Coded and Low Density Parity Check encoded signals.

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
  • NEW! 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 – no need to order separate output options
  • 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

10 thoughts on “RDMS™ Rackmount Receivers”

  1. Maximum RF Input is listed as +20dB. Is this the maximum safe limit? If so, what is the maximum usable RF input level? Or, if +20dB is the maximum usable RF input level, then what is the maximum safe limit?

    Reply
    • +20 dBm (100mW) is the recommended maximum safe RF input level. Less than 0 dBm input level is recommended for proper demodulation of any waveform.

      Reply
  2. All receivers work with windows or linux system?
    If yes, how you deal with windows or linux version changes?

    • The operating system in the RDMS™ is Arch Linux, which we custom-tailor to the application. We incorporate updates when they benefit the performance or features of the product.

      The remote control interface is via web browser, which can run under any OS.

    • Power consumption depends on the number of channels in the rack, the demodulators and decoders currently in use, and the data rate. For absolute maximums, you can use the following:
      Single channel: 60 watts
      Dual channel: 80 watts
      Dual channel with combiner: 100 watts

      For 3U units, excluding the -IP option (IP packet output of PCM data), the consumption is 10 watts higher than the figures given above for 1U units.

    • The RDMS™ ships with a comprehensive set of test data loaded onto the unit, and accessible through the browser interface. The AC power supply is CE certified, but the complete unit is not.
