Introduction
1.1 Description
This document describes the installation and operation of the Quasonix 3
rd
Generation Rack-Mount RDMS
TM
Telemetry Receiver and is updated to match RDMS
TM
System Version 19
. The RDMS™ (Receiver / DeModulator /
bit Synchronizer) is designed to downconvert, demodulate, and bit synch to a variety of RF telemetry signals from
flight-test aircraft. With an intuitive front-panel interface as well as an extensible web-based browser interface, and
antenna-tracking outputs, the Rack-Mount RDMS
TM
is capable of fulfilling a variety of flight test station
requirements.
The following waveform formats are supported by RDMS™:
•
PCM/FM (ARTM Tier 0)
•
SOQPSK-TG (ARTM Tier I)
•
ARTM CPM / Multi-h CPM (ARTM Tier II)
•
Legacy (PSK) suite, which includes:
•
BPSK
•
QPSK
•
Offset QPSK (OQPSK)
•
Asymmetric QPSK (AQPSK)
•
Unbalanced QPSK (UQPSK)
•
Asymmetric Unbalanced QPSK (AUQPSK)
•
Digital PM
•
STC
•
SOQPSK/LDPC
•
STC/LDPC
Of the aforementioned, RDMS™ provides true multi
-symbol trellis demodulation in all three ARTM modes,
PCM/FM, SOQPSK-TG, and Multi-h PCM. It also provides a clock signal, obviating the need for any outboard bit
synchronizer.
Modes that support LDPC use IRIG-standard low-density parity check coding to dramatically improve link margin
by up to 9 dB.
