TekBox TBFL1 Transient Limiter / AttenuatorThe TBFL1 is a combined transient limiter attenuator high pass filter, designed to provide optimum protection of spectrum analyzer or measurement receiver inputs when carrying out conducted noise measurements or other measurements where the input levels cannot be predicted with certainty or where accidental overloads may occur. Pin and schottky diodes combined with a multi stage 10dB attenuator result in a device which can withstand a continuous RF
