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.
