Function generators are used to generate waveforms such as the sine, triangular, and square shapes over a wide range of frequencies. A functional generator is ideal for electronic test and design sensor simulation, functional testing, and the general development, repair, and testing of electronic equipment. These generators can come in signal- and dual-channel models. Many models include software that allows you to integrate your work in formats that make editing data simple. Other features include input and output capabilities such as USB, LAN and GPIB for additional flexibility.
