Rohde & Schwarz SMR20 Signal Generator
The Rohde & Schwarz SMR20 Signal Generator is a state-of-the-art continuous wave (CW) generator designed to meet the demanding needs of modern testing applications. Boasting exceptional frequency coverage from 1 GHz to 20 GHz, this versatile instrument can be expanded to encompass frequencies as low as 10 MHz with the optional Frequency Extension (0.01 GHz to 1 GHz, option B11).
Engineered for superior performance, the SMR20 excels in spectral purity. Its advanced frequency synthesis utilizing fractional-N dividers results in remarkably low SSB phase noise and high levels of spurious suppression—critical parameters for achieving reliable and accurate receiver measurements. The incorporation of modern microwave filters in the output path guarantees impressive harmonics suppression, which is essential for precise scalar network analysis measurements.
