The Rohde & Schwarz SMY02 is an economical, high-performance RF signal generator designed for testing AM, FM, and phase-modulated receivers, as well as for general-purpose component measurements. Spanning a frequency range of 9 kHz to 2.08 GHz, it offers 1 Hz frequency resolution, an integrated 1 Hz to 500 kHz modulation generator, and low SSB phase noise, making it ideal for lab, production, and service environments.
