Rohde & Schwarz ZNBT8/B10/B108/B112

The analog R&S®SMB100A signal generator delivers excellent signal characteristics and high flexibility at low cost of ownership, perfectly matching the key criteria for a signal source. The technical characteristics of the R&S®SMB100A set new standards in the mid-range, especially the generator’s high output power and signal purity.

The R&S®SMB-B112 includes an electronic step attenuator. The R&S®SMB-B112L is without a step attenuator.
