R&S SMB100A Microwave Signal Generator

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).
 
Key facts:
 
- Wide frequency range from 100 kHz to 40 GHz
- Excellent signal characteristics with low SSB phase noise of typ. –128 dBc (at 1 GHz, 20 kHz offset)
- High output power of up to +27 dBm (meas.)
- All important analog modulations with AM, FM/φM and pulse modulation supported
- Compact size with only two height units and low weight

 

 
- All-purpose signal source
- Best signal quality in the mid-range
- High output power and wide level range
- Ideal for production
- Ready for aerospace and defense applications
- Flexible service concept
