What is a signal generator:

Signal generator is a device that can provide various frequencies, waveforms, and output level electrical signals. When measuring the amplitude, frequency characteristics, transmission characteristics, and other electrical parameters of various telecommunications systems or telecommunications equipment, and when measured the characteristics and parameters of the component device, the signal source or incentive source of the test is used.

Signal generator, also known as signal source or oscillator, has a wide range of applications in the field of production practice and technology. Various waveform curves are represented by triangular function equations. It can produce a variety of waveforms, such as triangular waves, sawtooth waves, rectangular waves (including square waves), and sine wave circuits are called function signal generators.

Principle of signal generator:

The signal generator is used to generate a sine signal (low frequency) with a frequency of 20Hz to 200kHz. In addition to the voltage output, some have power output. Therefore, it is very widely used. It can be used to test or maintain the frequency characteristics, gain, and frequency bands of low -frequency amplifiers in various electronic instruments and equipment. It can also be used as an external regulating signal source for high -frequency signal generators. In addition, when calibrating the electronic voltage gauge, it can provide an AC signal voltage. The principle of low -frequency signal generator: The system includes the main vibration level, the main vibration output regulator, the voltage amplifier, the output attenuator, the power amplifier, the impedance converter (output transformer), and the indicator voltage table.
