The Rohde & Schwarz SMV03 is a high-performance vector signal generator designed for RF and microwave testing. Combining the analog capabilities of the SML03 with an integrated broadband I/Q modulator, it operates over a frequency range of 9 kHz to 3.3 GHz, offering highly precise modulation, low phase noise, and an integrated electronic attenuator. It is ideal for automatic test systems, research and development, and servicing applications requiring digital standard emulation.
