The IZ245 receiver has software defined radio architecture based on FPGA. IZ245 can be used as a recording receiver, frequency scanner with scanning speed of 300 GHz/s and with extension modules as a Direction Finder and Responsive Jammer. Receiver offers analysis bandwidth of up to 80 MHz. IF preselection filters of various bandwidths are used to ensure high selectivity. Input of the receiver includes preselector to achieve excellent dynamic range with good sensitivity. Received IQ signals can be recorded to a removable internal fast NVMe disc drive with 2.5 TB capacity. Optical LAN interface together with hardware implemented TCP offers capability of 10 Gbit/s data transfer. VITA 49 protocol is supported for integration into large SIGINT systems. High stability reference oscillator can be disciplined by GPS through internal civilian GNSS receiver or external 1PPS signal. Built-in DAC with frequency range up to 6 GHz can be used as exciter for power amplifier to create responsive jammer. IQ signals stored on the SSD can be used as modulation signals for intelligent jamming. Direction finder antenna system can be controlled from the receiver to form a single channel direction finder. The receiver can be used as one of sensors for TDOA geolocation SIGINT system.
