The Rohde & Schwarz SME03 is a benchtop signal generator covering 5 kHz to 3 GHz, engineered for development and testing of digital mobile radio receivers and analog signal generation. It delivers leveled output from -144 dBm to +13 dBm with 0.1 Hz frequency resolution and 50 Ω output impedance. The instrument generates all common digital modulation modes—AM, FM, phase modulation, pulse modulation, and digital formats—without requiring external modulation or data sources. Its menu-driven interface supports user-programmable data sequences, TDMA structures, and RF/LF/level sweeps. A list mode enables programmable measurement sequences across up to 4096 frequency and level combinations with setting times below 0.5 ms. Ultra-low RF leakage makes it ideal for sensitive pager measurements. High spectral purity and low phase noise are core characteristics.
