#SINE WAVE GENERATOR GENERATOR#

There was a sharp distinction in purpose and design of radio-frequency and audio-frequency signal generators. RF and microwave signal generators can be classified further as analog or vector signal generators.Īnalog signal generators An analog RF signal generatorĪnalog signal generators based on a sine-wave oscillator were common before the inception of digital electronics, and are still used. Some models go as high as 70 GHz with a direct coaxial output, and up to hundreds of GHz when used with external waveguide multiplier modules. RF signal generators typically range from a few kHz to 6 GHz, while microwave signal generators cover a much wider frequency range, from less than 1 MHz to at least 20 GHz. RF and microwave signal generators normally have similar features and capabilities, but are differentiated by frequency range. RF (radio frequency) and microwave signal generators are used for testing components, receivers and test systems in a wide variety of applications including cellular communications, WiFi, WiMAX, GPS, audio and video broadcasting, satellite communications, radar and electronic warfare. An AWG is used in higher-end design and test applications.

An AWG is generally more expensive than a function generator and often has less bandwidth.

Unlike a function generator that produces a small set of specific waveforms, an AWG allows the user to specify a source waveform in a variety of different ways. Main article: Arbitrary waveform generatorĪn arbitrary waveform generator (AWG or ARB) is a sophisticated signal generator that generates arbitrary waveforms within published limits of frequency range, accuracy, and output level. General-purpose signal generators Function generator Leader Instruments LSG-15 signal generator Also, in April 1929, the first commercial frequency standard was marketed by General Radio with a frequency of 50 KHz. It supported a frequency range of 500 Hz to 1.5 MHz. In June 1928, the General Radio 403 was the first commercial signal generator ever marketed. Signal generators may be free-standing self-contained instruments, or may be incorporated into more complex automatic test systems. Modern general-purpose signal generators will have a microprocessor control and may also permit control from a personal computer. More general-purpose signal generators allow control of all the characteristics of a signal.

In general, no device is suitable for all possible applications.Ī signal generator may be as simple as an oscillator with calibrated frequency and amplitude.

These types include function generators, RF and microwave signal generators, pitch generators, arbitrary waveform generators, digital pattern generators, and frequency generators. There are many different types of signal generators with different purposes and applications and at varying levels of expense.

These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well. For an electronic musical instrument, see Sound module.Ī signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape.
