How to Choose the Right Signal Generator
White Paper
Testing today’s technologies requires many different types of signal generator The most popular signal generators provided by test and measurement equipment providers are:
- Function Generators
- RF Generators
- Pulse and Pattern Generators
- Arbitrary Waveform Generators (AWG)
There are many types of generators. Knowing when to use the right tool can help you get the best performance from your device.
Function generators
Most engineers know that function generators are cost-effective, easy to use signal generators. Function generators provide only a limited set of waveforms such as sine, square, and triangle. They are designed to be very easy to use for simple waveforms, and have limited memory for waveform storage. The basic controls include adjusting the generator’s frequency, offset, and other output variables, and adjusting modulation types.
Function generators are a reliable general-purpose source. Use function generators when you need a stable and repeatable stimulus signal. You can use them in applications requiring only periodic waveforms, such as stimulus response testing, filter characterization, and clock source simulation. Some of the more modern, advanced function generators are capable of generating simple AWG waveforms.
