You get everything you need to generate clean, precise, low-noise signals for testing your designs.


Trueform Technology

Keysight TrueformGenerate true point-by-point arbitrary waveforms with less jitter, more fi delity and greater resolution

Over the past two decades, direct digital synthesis (DDS) has been the waveform generation technology of choice in function generators and economical arbitrary waveform generators. DDS enables waveform generators with great frequency resolution, convenient custom waveforms, and a low price.

As with any technology, DDS has intrinsic downsides and limitations as well. Engineers with exacting requirements have had to either work around the compromised performance or spend up to 10 times more for a high-end, point-by-point waveform generator. Keysight’s Trueform technology offers a new alternative that blends the best of DDS and point-by-point architectures, giving you the benefits of both without the limitations of either. Trueform technology uses an exclusive digital sampling technique that delivers unmatched performance at the same low price you are accustomed to with DDS.

Unmatched capabilities for generating a full range of signals for the most demanding requirements
Waveform Summing

The 33500B Series waveform generators offer the common signals and features you expect, such as modulation, sweep, and burst. But the 33500B Series offers many more features that give you the capabilities and fl exibility you need to get your job done. Like an intuitive front-panel user interface that makes it easy to quickly relearn it when you’ve been focused elsewhere. Like built-in LAN, USB and GPIB interfaces that make it easy to control your instruments or transfer your waveforms to your instrument.

But the 33500B Series doesn’t stop there. It offers a variety of capabilities you won’t fi nd elsewhere—capabilities that help you accelerate your testing and get your project wrapped up faster:

Waveform summing and combining capability
Easily add noise to your signal for margin and distortion testing using only a single channel. You can create dual-tone multifrequency signals without a dual-channel generator, which means you can preserve your budget for other test needs. On a two-channel model, you can sum and combine up to four signals.

Variable-bandwidth noise
You can adjust the bandwidth of the built-in noise generator to control the frequency content of your signal. Apply just the frequency stimulus you need so you concentrate the energy of your waveform in frequency bands of interest.

DDS Skip



DDS technology may skip points at higher frequencies Trueform never skips points, and is always anti-aliased

Define any waveform shape and any waveform length using pointby-point arbitrary waveform capability.

Your waveforms are always anti-aliased for exceptional accuracy, and you can play them at any rate you select.

Play your signals as defined, at your exact sample rate, without the chance of missing short-duration anomalies that are critical for testing device reliability.








Flexibility in creating and playing waveforms

Waveform Creation

There are five ways to create arbitrary waveforms for use with the 33500B generator.

  1. Use the included Waveform Builder Basic software to edit and download a waveform file to the generator
  2. Use 33503A Waveform Builder Pro software to create more complex waveforms and sequencing
  3. Capture a waveform from an oscilloscope and download it to the generator
  4. Create a waveform in MATLAB,® Excel, etc. and download it to the generator
  5. Use the generator’s front panel to edit a waveform once it is in the generator You have lots of flexibility to choose the way you want to work.

Built-in Web browser
Easily set up and control your 33500B Series generator remotely over a LAN connection using the built-in LXI Web browser. You can monitor your tests and adjust settings from another office or room, or even from home.

Standard deep memory
If you want to test your design with long, complex waveforms with a variety of anomalies, you need to make sure your waveform generator has suffi cient memory. The 33500B Series’ standard memory is 1 MSamples deep. Typical DDS generators offer only a fraction of that amount but with the 33500B Series there is even a 16 MSample memory option available.

Use the optional high-stability timebase for even better accuracy
Get improved timebase stability and frequency accuracy using the optional high-stability timebase. The optional timebase offers 0.1 ppm stability, which is 20x more stable than the standard timebase over one year.
