Signal generatorOverview
The signal generator is a device that provides frequencies, waveforms and output level telecommunications, also known as
Signal source or oscillator. OtherCore functionsIs measuring the telecommunications system or
Key electrical parameters such as amplitude properties, frequency characteristics, transmission characteristics of equipment, and also properties of metaware
Precision tests with parameters. In production practice, it is widely used in electronic equipment manufacturing and communication systems
Areas such as integrated testing; in the field of science and technology, from basic scientific experiments to forward technology research and development, it is dependent on its provision
