The triangular waveform generator typically also has a square wave output as well, and it is used as the basis for generating all the waveforms in a function generator test instrument. This form of waveform is often generated using an operational amplifier acting as an integrator. Triangular wave: This form of signal produced by the function generator linearly moves between a high and low point.This form of waveform is again often used within digital applications. It is effectively the same as a square wave, but with the mark space ratio very different to 1:1. Pulse: A pulse waveform is another type that can be produced by a function generator.Used as a square wave generator, this test instrument provides a very useful source of a basic digital waveform. It consists of a signal moving directly between high and low levels. Square wave: Another very widely used waveform is the square wave. ![]() Sine waves are widely used in testing applications. Using the function generator as a sine wave generator is one of the more commonly used applications. This is the standard waveform that oscillates between two levels with a standard sinusoidal shape. Sine wave: A function generator will normally be able to act as a sine wave generator.With a function generator, there is no capability to have user generated waveforms, as it then would become an arbitrary waveform generator. The waveforms generated will generally be a sine wave, square wave, sawtooth, pulsed, etc. The name of the function generator arises from the fact that it is able to generate a number of different functions or waveforms.įunction generators are capable of producing a variety of commonly used repetitive waveforms. It is also interesting to note that many oscilloscopes now include a function generator - this can be included quite easily in many designs, and therefore manufacturers believe this will give their product additional functionality and appeal. Typically function generators are only able to operate at relatively low frequencies, some only operating to frequencies of around 100kHz, although more costly test instruments can operate at higher frequencies, up to 20 or 30MHz. This can be very useful in a number of testing applications. It cannot be programmed to create additional waveforms - an arbitrary waveform generator, AWG is required for this.Īpart from just generating the waveforms themselves, this type of test instrument has the capability to add a DC offset to the signal. The function generator is only be able to create the waveforms that are built in to the function generator. the mark space ratio, or the ramps of the different edges of triangular or sawtooth waveforms. In particular it can be made to become a sine wave generator, square wave generator, and triangular wave generator.Īlso a function generator may be able to vary the characteristics of the waveforms, changing the length of the pulse, i.e. Unlike RF generators and some others that only create sine waves, the function generator is able to create repetitive waveforms with a number of common shapes. Signal generator types: Signal Generator Basics RF signal generator basics Arbitrary waveform generator Pulse generatorĪ function generator is a specific form of signal generator that is able to generate waveforms with common shapes. įunction generator Function generator specs These features enable SIGLENT’s Function and Arbitrary Waveform Generators to provide a variety of high fidelity and low jitter signals, meeting the growing requirements of complex and intensive applications.Function Generators Explained Understand exactly what function generators are, how they are used & how they generate waveforms with common shapes: sine, square, pulse, triangular etc. The A-series are equipped with differential outputs, digital bus kits, sequence function and 48 V output range. In addition, the X-series and A-series provide true dual channels with internal waveform combination, flexible phase/channel control and copy/coupling/tracking between channels. Proprietary TrueArb & EasyPulse technology included in some of the models helps to solve the weaknesses inherent in traditional DDS generators when generating arbitrary, square and pulse waveforms. Common analog and digital modulations, sweep and burst are provided to support complex signal generation. ![]() SIGLENT’s Arbitrary Waveform Generators includes models with up to 1 GHz bandwidth, 5 GSa/s sample rate, 16-bit vertical resolution and 512 Mpts of memory depth.
