The compact, versatile R&S®SMB100A microwave signal generator with a frequency range up to 40 GHz provides outstanding spectral purity and high output power. In addition, it features easy operation, comprehensive functionality and low cost of ownership.
For even higher frequencies, the frequency range of the R&S®SMB100A can be easily extended with the R&S®SMZ frequency multiplier. The R&S®SMB100A plus R&S®SMZ solution combines easy handling with precise, adjustable output levels in the frequency range from 50 GHz to 110 GHz (adjustable output levels are not possible with R&S®SMZ170).
