Key facts
Maximum Attenuation > 60 dB, 70 dB (typ.)

Brief description The R&S®SMA100B together with the R&S®SMAB-K721 scan modulation option is the perfect choice for producing amplitude-modulated signals with a modulation depth larger than 70 dB. This allows very accurate simulation of peaks and nulls in complex antenna patterns.
