RF demodulator and processing – D00200-01A
This device has been developed for radar applications in order to drive an RF demodulator and implement digital processing algorithms (equalization and decoding, radar processing, direction finding).
It includes two proprietary products:
RF demodulator D00200-01A, input range of 400–4500 MHz, direct baseband conversion with local oscillator, two 16-bit ADCs.
Processing board D00200-02A. on-board FPGA VIRTEX VI (XC5VFX30T) and Power PC Freescale communicator (MPC8349), external link by a fast connection (Gigabit).
Multichannel Acquisition System – D00210100
The system includes a proprietary sub-rack, several acquisition boards (CAS) and an AM control board. The capabilities to allocate from 1 to 16 CAS boards and to acquire up to 256 analog channels make the system very flexible.
CAS board is capable of sampling simultaneously up to 16 analog channels with a maximum frequency of 144 KHz. ADC has a dynamics of 24 bit. High performance DSP (ADSP21469 SHARC) is included in the board.
AM control board is capable of managing up to 16 CAS boards. It includes a FPGA (XC5VFX30T) and a communication processor (Freescale PPC MPC8349) which are present on the board and it is provided with a fast communication link (Gigabit Ethernet).
Fast Recording System
The Fast Recording System (FRS) is an innovative device suitable for analog signal recording in the band of 10 – 1000 MHz. The maximum sampling frequency used is 2.2 GHz. The recording time supported is 30 minutes but can be easily extended to 60 minutes. The recorder, beyond starting the registration process by manual control, can also operate on trigger or gate basis like any commercial oscilloscope. The main difference that distinguishes it from an oscilloscope is the depth in the acquisition i.e. the length of the recording time.
With the addition of a “down-converter” it is possible to acquire any signal that exceeds the frequency of 1GHz. The FRS system is a complex system that is properly configured according to the needs of the Customer so that the configured product turns out to be exactly in line with the requirements and at the same time the cost does not exceed the allowed budget. For this reason a configuration sheet has been provided, attached, so that anyone interested in this device may request a FRS exactly in line with his needs.
FRS uses are various, some of them are shown in the attached flyer. In principle it can be said that this device finds its main use in all those sectors in which there is a need to record rapid and asynchronous events and where the possibility of analyzing with due care the temporal situation of the events themselves and their interrelationship is critical.
Electric Phase measurement unit for Laser Telemetry
This unit has been designed for laser telemetry applications where high performances are needed. Our company designed and developed the entire unit (RF and digital boards, DSP unit, two FPGAs, mechanical components, original processing algorithms).
Frequencies range from 5 to 230 MHz with a 0.001 degree phase resolution and output data are provided via USB port with data-rate ranging from 10 to 1000 measurements per second.
ASU2 Antenna Emulator
The ASU2 antenna simulator emulates the behavior of a phased array antenna of a modern fighter. The device is capable of generating a combination of analog RF signals which emulate the ones generated by the aircraft phased array.
We performed the entire design and system analysis, the Microwave subsystem specifications, the high performance real-time FW for several FPGAs and the system management SW.
We also realized dedicated HW products (such as FPGA-based interface boards, interfaces to drive the fast attenuators and bridge boards to send multiple LVDS signals from a board to another).
We also provided the entire HW and SW documentation (such as SW and HW description documents, test and validation plans, user manuals) as well as the support to the Customer Program Manager in order to detail the critical points and manage the project changes if they occur.
ASU2 Emulator
ASU2 emulates the behavior of a phased array antenna of a modern fighter relative to the optical fibers interfaces with the scenario generation system.
The system is a solid simulator developed in Dune which emulates the receiving section of the antenna and is capable of receiving and managing four real-time Hot-Link channels (600 Megabit/s per channel).
The incoming data are acquired via AlphaData boards equipped with a FPGA Xilinx Virtex IV. The dedicated MMI (Man-Machine-Interface) can acquire, arrange, display and store data on magnetic devices according to the user needs.
HF Modem
The system has been designed and developed on Motorola (DSP56309) platform for avionic HF communication applications. All the logic functions have been implemented according to STANAG 4197 standard.In particular the Doppler correction, the 4 DPSK modulation and demodulation, the end of frame realignment, the interleaving functions and the BCH coding and decoding have been implemented.
Torpedo Control System Simulator
The system has the purpose to emulate a torpedo control system to check and control off-line the entire logic of a real torpedo head.
DUNE has designed and developed both hardware and real-time software architecture for processing, visualization (exploitation of an industrial SIEMENS terminal) and graphic data exchange via LAN.
From an architectural point of view the system is based on VME bus and the control function is committed to a Radstone PPC (VxWorks O.S.) board. Moreover, 2 I/O commercial boards are located on the bus while the interface functions with the torpedo head are committed to boards designed and realized by DUNE.

Support our customers in conducting different tests, from vibration to thermal
The request from the notified body to conduct the test is to – somehow – force the natural frequency hopping of most RF protocols currently in use, and the same for automatic transmission gain to save energy.
This is exactly our job and one of our team’s proudest achievements. We can study products and understand how to do this in a particular case.
We also support our customers in conducting other tests, from vibration to thermal.
We have the expertise and knowledge to test systems and save manufacturers time, money, and energy.
