1 Introduction
1.1 Description
This document describes the installation and operation of the Quasonix Rack-Mount RDMSTM Telemetry Receiver.
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 Ethernet-based client interface, and antenna-tracking outputs, the Rack-Mount RDMSTM 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
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.
The Rack-Mount RDMS™ Telemetry Receiver is manufactured by:
Quasonix, Inc.

West Chester, OH 45069
CAGE code: 3CJA9
1.2 Nomenclature
The Rack-Mount RDMS™ (hereafter referred to as “RM RDMS™”) is available in a plethora of variations based on
the number of channels, frequency bands, demodulation methods, options, etc. The features and modes installed in
each unit are identified in the model number, as depicted in Figure 1.

Description
DC
Diversity combiner option
In the case of multi-channel receiver configurations with identical frequency bands and modes, a shorthand part
number can be used by including a multiplier code immediately following the initial frequency band and mode
character string. The multiplier code is “X2” for applicability to a two channel receiver configuration.
As an example, the following traditional part number, QSX-RDMS-RM2-M-1110-M-1110-DC, can be shortened to
QSX-RDMS-RM2-M-1110-X2-DC.
1.2.3 Detailed Option Descriptions
1.2.3.1 SAW Filter Option –14
This option adds additional SAW filters, for a total of 14. The additional filters are 70 kHz, plus 1.4, 3, 6, 14, and 28
MHz.
1.2.3.2 Continuous Tuning –CT
The CT option allows continuous tuning, including between specified bands. This option only applies to five-band
receivers.
1.2.3.3 Diversity Combiner –DC
The DC option provides a digitally implemented pre-detection diversity combiner. This option requires the dual-
channel configuration.
1.2.3.4 Viterbi Decoder (for Legacy PSK Only) –K7
The K7 option (k=7, rate 1/2) enables Viterbi decoding of a convolutionally encoded data stream, which converts it
back to the original (uncoded) source data stream.
Convolutional encoding adds redundant information to the transmitted data stream to help detect and correct bit
errors that may occur, particularly due to predominantly Gaussian noise. Use of convolutional encoding requires a
matching Viterbi decoder in the receiver to extract the source data. The decoded data rate is half the encoded data
rate. The receiver has two independent decoders, one for in-phase (“I”) data and one for quadrature (“Q”) data. For
BPSK, only a single decoder is used. Each decoder is compatible with the convolutional encoding described in the
“Consultative Committee for Space Data Systems, Recommendation for Space Data System Standards, TM
Synchronization and Channel Coding, CCSDS 131.0-B-1, Blue Book, September 2003, Section 3.”
1.2.3.5 Forward Error Correction/Low Density Parity Check (LDPC) (SOQPSK Only) –LD
The LD option provides the Low Density Parity Check (LDPC) forward error correction (FEC) decoder. This option
is only available with SOQPSK.
1.2.3.6 No Display –ND
The ND option provides a blank front panel with no displays or keypad.
1.2.3.7 RS-422 –RS
The RS option specifies RS-422 clock and data outputs on 3-lug triax connectors.
1.2.3.8 Clone Channel 2 –X2
The X2 option specifies Channel 2 configuration to match the Channel 1 bands and modes.
