IZT GmbH launched a new option for its powerful R4000 RF receiver. The 32768-point FFT option in combination with the 120 MHz real-time bandwidth ensures reliable detection of fast bursts and frequency-agile signals. Even the most advanced hoppers with extremely high hop rates are detected under demanding SNR environments. The Hopper Detector plugin provides real-time information about detected hoppers containing bandwidth, dwell time and time-of-arrival information.
