Key Critical Specs You Should Know Before Selecting a Function Generator

Function generators are not built the same.


Selecting a benchtop function generator for your everyday use is very important. You want to be sure it produces the signal types that you need for your tests without introducing unwanted jitters, noise, harmonic distortions, or signal flaws. Introducing unwanted signal flaws inadvertently causes false test rejects due to your function generator. It is a common mistake to purchase the least expensive one you can find from your local store or distributor. Function generators are not built the same. Most generate the same basic waveforms and some advance waveforms such as modulated waveforms and some burst waveforms. However, the difference is visible in the subtle details of waveform distortions, jitter or phase noise, and signal integrity over a broad range of frequencies.
