Rohde and Schwarz SMF100A

The Rohde & Schwarz SMF100A is a high-performance microwave signal generator engineered for demanding RF and microwave applications in research, development, production, and maintenance environments. Delivering exceptional signal purity and frequency accuracy across frequencies from 100 kHz to 43.5 GHz, the SMF100A sets performance standards in aerospace, defense, and communications testing. Its innovative synthesizer architecture achieves –120 dBc SSB phase noise at 10 GHz (10 kHz offset) and very low wideband noise of –148 dBc, enabling precise characterization of sensitive RF systems. The instrument combines rapid frequency and level settling—<4 ms and 10 MHz offset; 1 Hz bandwidth; +10 dBm)
• Non-Harmonics Suppression: Typically –67 dBc (1 GHz 3 kHz offset)
• Harmonics: Typically –55 dBc (1 GHz ≤ f ≤ 43.5 GHz; +10 dBm)
• Frequency Resolution: 0.001 Hz
• Frequency Setting Time: <4 ms
• Level Setting Time: <3 ms
• List Mode Switching: <700 µs per entry
