Precise signal generation for complex signal environments
Keysight WG2-class Advanced waveform and function generators include the 33500 Series. They provide clean, precise signals for simulating real-world conditions and ensuring reliable device characterization in complex signal environments like multitone communication signals in RF systems, pulse-modulated waveforms in radar and digital communications, and frequency hopping in wireless communications. With ultra-low jitter and minimal total harmonic distortion (THD), our Advanced waveform and function generators enable realistic simulation and reliable testing of devices in high-signal-complexity scenarios. Choose one of our popular configurations or configure one specific to your application.

Frequently asked questions
Signal integrity refers to the quality and accuracy of an electrical signal as it travels through a circuit or system. In a waveform generator, signal integrity determines how clean, precise, and stable the output waveform is. The following are a few key reasons why signal integrity is important:
- Accurate Testing: Poor signal integrity (e.g., jitter, noise, distortion) can lead to misleading test results and mask real issues in the device under test.
- High-Speed Designs: In high-frequency or fast-rise-time applications, even small signal distortions can cause major performance problems.
- Reliable Measurements: A waveform generator with high signal integrity ensures that what you send into your system is true to what you intended— free from artifacts or signal degradation.
In-phase quadrature modulation, or IQ modulation, is the dominant modulation scheme in communication applications. It is popular because of its efficient use of bandwidth, which continues to be a challenge in our data-hungry world. Testing with simulated IQ signals is critical because designers face a continual bandwidth crunch in a spectrum filled with interference.
For example, you need to test your design's limits to ensure real-world performance. To do this, you need to first generate an ideal signal using a function generator to test its ideal performance. Function generators play a crucial role in simulating nonideal IQ signals. By adjusting the gain balance between the two channels and the amplitude offset for each channel, you can create nonideal signals. You can even perform skew adjustment to shift either the I or Q baseband signal in time with picoseconds of resolution. Some function generators allow you to add noise, random jitter, or deterministic jitter to the signal.
Waveform sequencing lets you create multiple configured waveforms with several common segments. Sequencing lets you build long, complex waveforms using minimal instrument memory. With waveform sequencing, you can save memory by replaying different shorter waveforms at various locations in your signal as needed.
Many tests require long waveform memory records. Eventually, the necessary record length may exceed the available waveform memory. Sequencing is a way to increase a signal’s length. In sequencing, different waveform segments repeat (or play back one after the other) through a user-defined sequence list.
