The Rohde & Schwarz SME02 is a synthesized signal generator spanning 5 kHz to 1.5 GHz, engineered for development and testing of digital mobile radio receivers and RF systems. It generates signals compliant with major digital radio standards while supporting both digital and analog modulation in a single instrument. The SME02 delivers output power from -144 dBm to +13 dBm with spectral purity better than -30 dBc, making it suitable for sensitive receiver characterization and component validation.
