What are Function and Signal Generators?
A signal generator is a device that creates electronic signals, typically varying in voltage or current over a short period, with varying waveforms, or shapes, where the voltage increases or decreases at different rates as it reaches its peak value. There are many different types with many different applications. Function generators, arbitrary waveform generators, and vector signal generators are common types of specialized signal generators.
What is the difference between a Signal Generator and a Function Generator? - A Signal Generator is a fairly simple piece of kit that can produce basic waveforms for Electronic Design, Test and Repair projects, typically producing Sine, Square & Sawtooth waveforms with possibly some variation of those. A function generator is a more sophisticated instrument that can produce waveforms of multiple programmed designs, used more in advanced development projects where simple waveforms can create limitations.
What is an Arbitrary Function Generator? - An arbitrary function generator is a combination of Signal and Function Generation -it has a pre-set list of waveforms or patterns to output, combined with being able to change the parameters of waveforms, such as frequency, the amplitude and offset, and add some basic forms of distortion or modulation.
