The Rohde & Schwarz SMV03 is a vector signal generator spanning 9 kHz to 3.3 GHz, delivering complex modulated signals for communications testing, R&D, and service applications. Built on the proven R&S SML03 analog platform, it integrates a broadband I/Q modulator enabling generation of any digital signal format when paired with an external I/Q source. The instrument excels in high data-rate testing such as WLAN standards, with I/Q bandwidth exceeding 50 MHz and interruption-free level adjustment across a 30 dB dynamic range.
