1.1 Description

This document describes the installation and operation of the Quasonix Compact RDMS™ Telemetry Receiver. The
RDMS™ (Receiver / DeModulator / bit Synchronizer) is designed to demodulate RF signals in several formats:

PCM/FM (ARTM Tier 0)

SOQPSK-TG (ARTM Tier I)

Multi-h CPM (ARTM Tier II or ARTM CPM)

Legacy (PSK) suite, including

BPSK

QPSK

Asymmetric QPSK (AQPSK) Requires -37 option

Asymmetric Unbalanced QPSK (AUQPSK) Requires -37 option

Offset QPSK (OQPSK)

Unbalanced QPSK (UQPSK)

Digital PM
The RDMS™ provides true trellis demodulation in ARTM Tier 0, Tier I, and Tier II modes, delivering BER
performance within 0.2 dB of theory. It also provides a clock signal (two clock signals in the AQPSK and AUQPSK
modes), obviating the need for any outboard bit synchronizer.
The RDMS™ is manufactured by:

1.2 Nomenclature

The RDMS™ is available in a number of variations, depending on the options specified at the time of order. The
features and modes installed in each unit are identified in the model number, as depicted in Figure 1.
