Function Generator

See Function Generator Products

A function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine, square, triangular and sawtooth shapes. These waveforms can be either repetitive or single-shot (which requires an internal or external trigger source).

The GP1616H function generator is a programmable instrument capable of generating predefined Sine, Square, Triangle, Ramp, Haversine, Haver triangle and Pulse waveforms as well as a programmable DC output. The firmware is customized to be fully compatible with the HP 8116A GPIB command set. Software test procedures using the original HP8116A instrument require no code modification when upgrading to the GP1616H.

National Instruments function generators for PXI and PCI combine the same features as stand-alone function generator with the flexibility and speed of computer-based modular instrumentation. By using direct digital synthesis, NI's function generators have precise frequency control, a useful feature for clocking other modular instruments such as high speed digital I/O modules or digitizers.


Today's designs are often complex, demanding a variety of stimulus signals during test. With standard waveforms, arbitrary waveform capability and signal impairment options, a Tektronix Function Generator supports a wide range of application needs with one instrument. Best-in-class Function Generator performance from Tektronix AFGs ensures signals are accurately reproduced.
