Have you ever heard about signal generator? If you haven't heard about it, you need to read this article. This article will give you a short explanation about the function and types of signal generators.
Signal generator is also called as a test signal generator. This device is used to produce electrical impulses. You can use this device to test, repair and test electronic and acoustic devices.
This device has many types based on its function. There is no one signal generator that is suitable to all devices and purposes. This device has two major categories. They are function generators and arbitrary waveform generators.
The simpler type is function generator. This device produces wave-like form. This generator has a circuit that produces repeating wave (sine wave). This generator is often used in repairing and designing electronics.
This generator will send signals to test the particular circuit which is connected to an oscilloscope to measure the output signal. Since there are many kinds of electronic appliances, function generator has many kinds of type and model to fulfill your needs.
Arbitrary waveform generator has some differences with function generators. This device produces more forms than the previous device. This generator produces many kinds of wave such as triangular, square, etc. this device is more expensive than any other signal generator.
Before people found signal generator, they use similar device to produce signal. When people build a new radio station, they will measure another radio's performance as their standard. This radio measurement is called as "golden radio".
This method is cheaper and has a lot of advantages but they have one main disadvantage. This golden radio's performance is unstable. This condition makes golden radio can't be used as reliable equipment. You need to choose modern signal generator to get the most accurate, precise and specific test equipment.
