key facts

verification of immunity using realistic scenarios involving multiple lte and wimax^™ emitters
high total field strength of ≥ 1 v/m peak envelope power (pep) at radar antenna 200 m away
high suppression of intermodulation products and spurious emissions in radar band to < –130 dbm/mhz through decoupled, low-intermodulation filters
flexible setup at 100 m to 300 m from radar for taking local conditions into account
tests in normal radar operating mode
flexible, modular system based on standardized instruments; expandable for other interference tests

brief description

the r&s^®ts6650 detects potential interference to air traffic control (atc) radar systems caused by lte and wimax^™ emissions in the adjacent frequency band. the effectiveness of counteraction is verified on the radar.
