Features, specifications, and options of the Gen 3 Rackmount RDMS™ Telemetry 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.
Get Stronger Core Performance
Benefit from lower noise, higher gain, faster sync, and greater ability to hold sync than any competing demodulator—in all ARTM modes, under the most challenging conditions.

Understand Your Data’s Quality—For Real
RDMS features the industry’s most accurate Data Quality Metric (DQM)—a real-time assessment of BEP—coupled with flawless Data Quality Encapsulation (DQE), rigorously powering downstream processes like BSS.

Ensure Optimal Data Output
The receiver’s integrated best-channel selector—a Quasonix exclusive—uses DQM bit by bit to choose the highest-quality data, matching or outperforming traditional maximal-ratio combining across all channel conditions.
