Application Selection of RF Signal Generator

　　More than a decade ago, the RF signal generator market was mainly dominated by foreign companies such as Agilent and Rhodes. With the progress of the domestic market, more and more scientific and technological personnel have invested in the development of commonly used testing instruments such as signal generators, frequency meters, and oscilloscopes. With the development of precision electronic instruments in China, achievements have also been made in related testing instruments, At present, more enterprises and institutions prioritize localization when choosing, and choose domestic manufacturers to produce signal generators, frequency meters and other related measuring instruments and equipment.

　　Regarding the introduction of RF signal generators into equipment, a more intuitive explanation can be provided using the SYN5651 signal generator as a case study. This equipment meets the requirements of RF based signal generators, with frequencies ranging from 10 μ Hz, up to a frequency of 30GHz. The function of the signal generator meets the requirements of the JJG 173-2003 Signal Generator Verification Regulations and the JJG 502-2017 Synthetic Signal Generator Verification Regulations. Its principle adopts digital synthesis and phase-locked technology, which meets the characteristics of high reference frequency, wide range output, low phase noise, and fast switching of low harmonics.

　　RF signal generator is mainly used to generate RF signals, which are used to generate continuous wave signals or modulated signals using RF signals as carriers. It is a basic testing instrument that must be used in the fields of RF and microwave testing and development. Its internal components mainly consist of oscillator unit, amplifier unit, attenuator unit, control unit and other units. The oscillator unit interacts with modules such as tuned oscillator and loop filter to correct important functional reference parameters such as frequency, phase difference, and phase noise, completing the functions specified by the RF signal generator or continuously optimizing its functions and parameter items.
