Waveform Generators produce large, complex analog waveforms in a sequential manner or using real-time streaming. These instruments are ideal for applications in scientific research and testing of consumer electronics, automotive, and aerospace/defense.

Function generators can produce precise waveforms including sine, square, triangle, and ramp with very high signal purity and accuracy. These instruments are ideal for validation, verification, and production test of semiconductor devices, consumer electronics, automotive, and aerospace/defense that only require repetitive signals to ensure proper functionality.

Arbitrary Waveform Generators
Arbitrary waveform generators can produce precise waveforms including sine, square, triangle, and ramp as well as arbitrary, user-defined waveforms. When used in modular instrumentation platforms like PXI, arbitrary waveform generators often allow user to create sequences of waveforms or enable streaming continuously from a host or peer-to-peer instrument. These instruments are ideal for tightly synchronized, mixed-signal test systems in scientific research or test of semiconductor devices, consumer electronics, automotive, and aerospace/defense that require multiple types of input signals and flexible generation capabilities.

Figure 3: Arbitrary waveform generators can produce signals with user-defined values. Some arbitrary waveform generators have a lot of memory for very long waveforms, have the ability to generate different pieces of waveform according to a script, or can stream waveform data from a host for a continuously variable signal over time.
