The analog function generator and digital function generators are types of function generators. fV9Electronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product This generator is considered as the most versatile instrument in the electrical and electronics laboratory because the waveforms generated by this generator have applications in different areas. The waveforms of these frequencies may be adjusted from hertz to a hundred kHz. The common waveforms generated by this generator are sine wave, square wave, triangular wave, and sawtooth waves. fV9Electronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product What is Function Generator?ĭefinition: The function generator is defined as a type of device which produces various types of waveforms as its output signals. A brief explanation of this generator is discussed in this article along with the circuit diagram and block diagram. The frequencies provided by this generator is up to 20 MHz.
There are two types of function generators they are analog and digital. This generator generates five types of waveforms, they are sine, square, saw-tooth, triangle, and rectangle waveforms. The different types of waveforms have different frequencies which can be generated by using the instrument as a function generator. They can replicate the capabilities of traditional analogue pulse generators whilst adding many additional facilities such as pulse modulations.Function Generator is a type of instrument which is used to generate different types of waveforms like sinusoidal, triangular, rectangular, square waveforms.

The Aim-TTi TGP3100 Series are true pulse generators using all digital techniques. This differs markedly from the pulse function of most DDS function generators where width and delay are defined by the system clock period and are one to two orders of magnitude less precise.
They can also operate in an asynchronously triggered mode with low jitter. Unlike DDS based function generators, pulse generators operate with very low jitter and high resolution of pulse width and delay. The Aim-TTi TG300 series are good examples of a low-cost analogue Function Generators. The advantages of analogue generators are restricted to the purity of the waveform. The use of analogue technology is now limited to low cost basic generators and to high performance very low distortion signal sources. DDS has largely replaced Analogue in modern Function Generators. Sinusoids and square waves are generated from this. True Arb architecture avoids the clock jitter associated with DDS arbitrary generators.Īnalogue generators use a voltage controlled oscillator to generate a triangular waveform of variable frequency. An external sample clock can also be used as the clock generator. Arbitrary waveforms may be replayed at a specified waveform frequency, period or sample rate. Arbitrary Generators with a variable clock permit waveform linking, looping and sequencing. These may be described as Universal Arbitrary Waveform Generators or simply Arbitrary Waveform Generators (AWG) or Variable clock Arbitrary generators. These generators also use DDS for the production of standard waveforms (function generator mode), but use a variable clock for generating arbitrary waveforms. The Aim-TTi TGF4000 series represents the latest and most accurate use of DDS technology and digital control architecture to release the ultimate DDS performance in a Function/Arb /Pulse generator. These are most commonly described as either Function/Arbitrary Generators or Arbitrary/Function Generators (AFG). These generators use DDS for the production of both standard waveforms (function generator mode) and arbitrary waveforms. There are two distinctly different ways in which arbitrary waveforms can be produced: DDS and Variable Clock.Īrbitrary Generators: Direct Digital Synthesis (DDS) DDS offers fast switching between output frequencies, fine frequency resolution, and operation over a broad spectrum of frequencies.Īrbitrary generator describes a class of digital generator potentially capable of reproducing any waveform shape. Triangle waves and other waveforms are limited to a much lower frequency.ĭirect Digital Synthesis (DDS) is a method of producing an analogue waveform usually a sine wave by generating a time-varying signal in digital form and then performing a digital-to-analogue conversion.
Basic generators only offer sine and square waves up to the maximum generator frequency. Digital generators use a digital to analogue converter (DAC) to generate a wave shape from values stored in memory.
