CAUTION
LEGEND
The exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the
literature accompanying the product.
The lightning flash with an arrowhead symbol within an equilateral triangle is intended
to alert the user to the presence of uninsulated ‘dangerous voltage’ within the product’s
enclosure that may be of sufficient magnitude to constitute a risk of electric shock to
persons.

Cleaning.
Unplug the unit before cleaning.
Clean only with dry cloth.
THIS PRODUCT SHOULD NORMALLY ONLY REQUIRE A WIPE WITH A SOFT, DAMP, LINT-FREE CLOTH.
DO NOT USE PAINT THINNER OR OTHER CHEMICAL SOLVENTS FOR CLEANING.
Opening of the product chassis.
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK).
NO USER SERVICEABLE PARTS INSIDE; THE PRODUCT CHASSIS SHOULD ONLY BE OPENED BY
QUALIFIED PERSONNEL FOR MAINTENANCE PURPOSE (EXCEPT FOR OPPOSITE INSTRUCTIONS IN THE
USER’S MANUAL).
Technical Maintenance.
Refer all servicing to qualified maintenance personnel. Servicing is required when
apparatus has been damaged in any way, such as power supply cord is damaged,
liquid has been spilled or objects have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate normally, or has been dropped.
THE QUALIFIED MAINTENANCE PERSONNEL MUST TAKE REASONABLE PRECAUTIONS TO FACE THE
OBVIOUS DANGERS.
Powers sources.
Only connect the apparatus to a power supply as described in the operating
instructions or as marked on the apparatus.
Turning off the power switch does not completely isolate this product from the power
line so remove the plug from the socket if not using it for extended period of time.
Unplug this apparatus during lightning storms.
Power cord protection.
Power supply cords should be routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying particular attention to cords and
plugs, and the point where they exit from the appliance.

Note: FCC Rules
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
—Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications to this equipment not expressly approved by Safran Data Systems Inc
may cause, harmful interference and void the FCC authorization to operate this equipment.

CE MARKING
Markings are placed at the rear of the unit, regarding the power ratings and compliance.
The symbol on the chassis indicates that it is in compliance with the Electromagnetic
Compatibility directive (2014/30/UE), the low Voltage directive (2014/35/UE) and RoHS directive
(2011/65/UE). A declaration of Conformity UE is available by contacting technical support. This
equipment is a:
✔Group 1 Class A product
Recommendation concerning the cabling:
CE certification has been carried out with 3-meter interconnecting cables with remote equipment.
SAFRAN DATA SYSTEMS recommends the use of high quality interconnecting cables type. The high
quality recommended user interconnecting cables are “shield twisted pair” or “coaxial cable” industrial
type with cable shield. The cable shield will provide the necessary mechanical protection.
Not using this high quality designed cable could result in unexpected intersystem / extra system
electromagnetic emission and susceptibility.

1 AIM
This user’s manual describes the relevant information for operating the Safran Data System (ZDS) RX-1
Compact Operational Receiver.
The RX-1 is a 1U dual-channel multiband telemetry receiver, including multi-mode TIER demodulators, bit-
synchronizers, and state-of-the-art signal processing functions enabling to get the most data from flight test
missions. Its compact size and all its interfaces allow its use for any kind of mobile or fixed tracking and
telemetry stations, up to a final delivery of data over Ethernet.

3 DESCRIPTION
3.1 General description
The RX-1 is dedicated to IRIG106 telemetry reception, supporting any type of IRIG 106 telemetry signal in
P-, C-IF, L-, S- and C-band (optional) with 2 channels. It is used for both high dynamics tracking and
telemetry. The implementation of 8 pre-selection SAW filters allows the RX-1 to have excellent adjacent
channel rejection, better AGC regulation and high dynamics (>90dB). One direct consequence is its
capacity to maintain auto-track of the tracking antenna much farther as the AGC and AM signals can be
retrieved at a lower SNR.
Not only the RX-1 features a choice of 30 IF filters (from 3kHz to 40MHz) but customized filters can also be
implemented by firmware upgrade to better fit the customer specific application. In addition to a high-
performance pre-D combiner (available in Frequency and Polarization diversity) and an outstanding
Enhanced Adaptive Equalizer for multipath mitigation (optional), the RX-1 features a TIER multi-mode
demodulator with trellis for each channel (PCM/FM, SOQPSK-TG, ARTM-CPM) with excellent
performances, in terms of locking threshold, BER, as well as very short (re)acquisition time following a
signal loss.
It also features real time spectrum and eye pattern display for all channels (while demodulating), and a
thorough set of inputs and outputs. Furthermore, The RX-1 incorporates the latest features from IRIG-106
as LDPC decoders (optional).
A special option on the RX-1 allows the pre-d combining of two IF 70MHz signals played back from the
Cortex RSR into the RX-1 along with their digital AGC signals. Finally, the RX-1 has the capacity to
distribute the TM data over Ethernet (TMoIP) with embedded time stamp. TM data is raw (ie non-
synchronized). The format is either a proprietary native ZDS format or as per IRIG 106 chapter 10
standards. Both are compatible with a large number of software-based telemetry processing software used
to process, extract and display the parameters.
