The Noisecom UFX-BER series consists of precision Eb/No (Energy per bit to Noise power spectral density ratio) generators. These highly automated instruments provide accurate, repeatable control of carrier-to-noise (C/N), C/No, and C/I ratios, making them essential for bit error rate (BER) testing in satellite, wireless, and military communications.
