The R&S®SFI100A Wideband IF Vector Signal Generator meets the bandwidth requirements of high-demanding applications including early-stage 6G research, millimeter-wave WLAN and automotive radar. This compact instrument delivers an RF modulation bandwidth up to 10 GHz and can generate fully calibrated RF signals. The R&S®SFI100A can seamlessly connect to the R&S®FE110ST and R&S®FE170ST upconversion frontends to cover the frequency range from 70 GHz to 175 GHz. The generator provides full control over the connected frontends, forming an all-in-one integrated test solution. In addition to RF ports, the R&S®SFI100A is equipped with analog IQ outputs for wideband signal generation at the baseband stage.
