  • 1. Ministry of Defence Electronics, Logistics and Property Management Co. Communication Simulator Development of a universal signal generator: •Generate modulated radio signals •Accept real-time audio input •All of the parameters defined by the remote control software running on a computer •The parameter changes can be scheduled and replayed Modulation sources Remote control BITE Baseband Radio DSP DMU FCU FEU Digital Signal Processor Digital Modulator Unit Frequency Conversion Unit Frequency Extension Unit RF output CS-2500-E Audio input 1 - 2500 MHz 1 Hz -100 - 0dBm 1 dB CW/SSB/ISB/AM/FM ASK/FSK/PSK/QAM PULSE/BURST/DSSS/FHSS TV/STCK/FDM/TDM/PCS SINE/NOISE/MORSE/TTY/VFT VOICE/MODEM/FAX PRBS/BARKER/ASCII TCP/IP on TP Ethernet Internal, Serial, Remote Control Basic technical parameters: Frequency range Frequency resolution Output power range Out power resolution Modulation formats Channel Controller Unit (CCU) The CS-2500-E multifunctional signal generator: functional block diagram and realisation The digital modulator is able to generate wide variety of modulation formats from simple analog modulations to multilevel digital formats with transmission security like spectrum spreading. Control software package Higher level system could be integrated using the basic signal generator element. Up to 16 emitters can be controlled by the software to produce a realistic radio electronic environment at the output of the simulator. www.sagax . www.sagax.hu Scenario editor (24h with 1sec resolution) A A: Audio in from tape recorder Control SW Control BUS Control panel A #1 RF Channel RF #2 RF Channel Σ PC A Mapware visualisation #16 RF Channel Splitter SUT Monitor output for calibration External RF Source External Noise Source Control computer RF channels Output stage Sagax, Ltd.
