Signal Generator Vs Function Generator

A signal generator creates controlled and precise waveforms of varying shapes to test, debug and troubleshoot electrical setups. Whether you’re fine-tuning a high-fidelity audio system or developing next-gen radar tech, a signal generator is an indispensable tool for ensuring your electrical design works as expected.

Function signal generator vs function generator produce a limited and predefined set of periodic waveforms at precise frequencies, such as sine waves, square waves, triangular waves and sawtooth waves. They may also offer the ability to add a DC offset to a signal.

Signal Insights: Comparing Signal Generators and Function Generators

Most function generators have a series of controls that allow you to adjust a specific feature or characteristic, such as the mark space ratio on a pulse waveform, or the slope of different edges on a sawtooth waveform. They also typically have built-in RF waveforms that can be used to simulate transmission signals.

A more advanced and sophisticated type of function generator is an arbitrary waveform generator (AWG). This offers the ability to create a user-defined waveform using the onboard memory, making it easier to test complex or specialist electronic circuits. AWGs often come with a range of connectivity options that are more convenient for use with setups that include other testing equipment such as oscilloscopes. In addition, AWGs are able to generate more sophisticated electronic waveforms such as a wide range of digital modulations and encoding schemes.
