Series ** generators support a variety of analog and digital modulation modes. Due to the use of state-of-the-art circuit technology and open system architecture, this series of instruments can always keep pace with the latest advances in the field of digital modulation technology, both at present and in the future. The SMIQ family consists of four models, each varying in frequency range and application field. SMIQ02 and SMIQ03 are unmatched in terms of ** variety and ** quality, so users requiring product development and type licensing testing will have little difficulty in choosing a ** generator. Economy SMIQ02E and SMIQ03E are designed for production testing and their emergence provides a cost-efficient solution for cash-strapped users.
