The SMIQ03B is a vector signal generator with a frequency range of 300kHz to 3.3 GHz. The high-grade I/Q modulator fitted as standard ensures minimum error vector magnitude and high intermodulation suppression.Using modern digital signal processor (DSP) technology, the versatile concept allows the generation of high-precision digital modulation signals at high bit rates without any limitations on modulation modes orstandards. In addition to digital modulation, the SMIQ03B providesthe full range of analog modulation modes as well as simultaneous modulation capability.
