The function generator is a multi-waveform source. It can produce sine wave, square wave, triangular wave, sawtooth wave, and even arbitrary waveform. Some function generators also have modulation functions, which can be AM, FM, phase modulation, pulse width modulation and VCO control.
It has a wide frequency range, the use of a wide range, it is an indispensable universal signal source. Can be used for production testing, instrument maintenance and laboratory, and also widely used in other fields of science and technology, such as medicine, education, chemistry, communication, geophysics, industrial control, military and aerospace.
