Categories Related to Function Generators
A function generator is a device that generates various electrical waveforms. It can produce periodic waveforms such as sine, square, triangular, ramp, and noise waves. Function generators are used for testing electrical devices and analyzing their characteristics. They can generate both continuous wave (CW) and pulse oscillations, with some models equipped with additional features like trigger, gate oscillation, and sweep oscillation.
The generator allows the setting of parameters like waveform amplitude and period.
Function generators are primarily used in electrical laboratories and research institutes to investigate the response of electrical elements and circuits to specific waveforms. They are commonly used alongside oscilloscopes, which measure and display electrical waveforms.
While function generators are high-priced due to their versatile waveform output capabilities, they are essential as inspection devices.
Function generators typically use the direct digital synthesizer (DDS) method, consisting of a phase accumulator, waveform ROM, and a D/A converter. This approach allows for stable, high-frequency accuracy and the output of arbitrary waveforms.
When selecting function generators, consider features like overshoot and jitter. It's important to choose a generator with minimal overshoot and a small jitter for accurate signal reproduction. Additional features like a variety of waveforms, external trigger capability, and multi-output synchronous generation are also important.
Function generators offer several waveform generation functions:
