Signal Generator Applications

Signal generators, also known as signal sources or oscillators, are widely used in production practices and scientific and technological fields. Various waveform curves can be represented by trigonometric function equations. A circuit capable of generating various waveforms, such as triangular waves, sawtooth waves, rectangular waves (including square waves), and sine waves, is called a functional signal generator. Function signal generators are widely used in circuit experiments and equipment testing. For example, in communication, broadcast, and television systems, RF (high frequency) transmission is required. Here, the RF wave is the carrier wave. To carry out audio (low frequency), video, or pulse signals, an oscillator capable of generating high frequencies is required. In industries, agriculture, biomedicine, and other fields, such as high-frequency induction heating, melting, quenching, ultrasonic diagnosis, and nuclear magnetic resonance imaging, oscillators with high or low power, high or low frequency are required.
High frequency, ultra high frequency, and microwave signal generators have formed a series of standard signal generators, not only achieving solid-state, but also emerging synthetic signal generators and programmable signal generators; Performance has been continuously improved in terms of frequency range, accuracy, stability, resolution, and output level range, accuracy, frequency response, spectral purity, etc. A synthetic high-frequency signal generator with a microprocessor, whose frequency, output, modulation, and other controls have all been keyboarded, and has a 6-digit display.
