The Aeroflex IFR FB2000A is a frequency-tunable signal generation platform for performance testing of communication systems, receivers, and jammers. It delivers programmable carrier and noise sources with precise control of RF channel impairments including noise, interference, and fading profiles. The system excels at Bit Error Rate (BER) versus Signal-to-Noise Ratio (SNR) characterization across CATV, satellite, DTV, MDS, and wireless applications.
