Trueform Technology

Generate true point-by-point arbitrary waveforms with less jitter, more fidelity and greater resolution

33500B Series waveform generators with exclusive Trueform signal generation technology offer more capability, fidelity and flexibility than traditional DDS generators. Use them to accelerate your development process from start to fi nish.

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.

The Keysight Technologies, Inc. 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.

and features you expect, such as modulation, sweep, and burst. capabilities and flexibility you need to get your job done. Like an it when you’ve been focused elsewhere. Like built-in LAN, USB transfer your waveforms to your instrument.

But the 33500B Series doesn’t stop there. It offers a variety of 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.

Trueform Technology

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

The images at right show approximately 10 dB increase in amplitude at 50 kHz when the bandwidth is reduced 10x. You can see how the signal energy is increased in the frequencies of interest when the bandwidth is reduced, instead of being spread over a very wide bandwidth with lower amplitude at all frequencies. Dual-tone signal created by summing waveforms using the modulation type, “Sum.”

5DDS 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 point-by -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.Waveform sequencing

Waveform sequencing lets you create multiple configured waveforms with several common segments and lets you build long, complex

waveforms using minimal instrument memory.Scope display of waveform.

6Pseudo-random binary sequence

(PRBS) pattern generation

Test your digital serial buses by streaming standard PRBS patterns— like PN7 and PN19—without the need for a separate pulse generator. With fewer instruments, setting up your tests is easier. You won’t find these built-in PRBS patterns in competitive waveform generators.

Flexibility in creating and playing waveforms 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.Smart phone and tablet access

833500B Series waveform generators offer the

following advantages:

Lowest jitter

With 12x better jitter than anything in their class, 33500B Series waveform generators offer unparalleled edge stability. You can even use them as a system clock for timing and triggering your other instruments. With better jitter performance, you can place edges more accurately, helping you reduce timing errors in your circuit design.

Lowest harmonic distortion With total harmonic distortion of just 0.04%, the 33500B Series offers 5x better fidelity than other generators. Clean, spurious-free signals don’t introduce noise or artifacts. See your design’s characteristics, not the waveform generator’s, in your measurements. Faster edge times

The 33500B Series’ 8.4-ns rise and fall times are more than twice as fast as you’ll find in typical waveform generators. You can place edges with more confidence and more accurately set trigger points. Because of the faster transition, higher harmonic content is created, which helps you expand your understanding of your circuit.

Trueform Technology

Signal integrity: Test your devices with confidence that your signal generator is outputting the signals you expect

Keysight 33500B Series waveform generators offer the lowest total

harmonic distortion (THD) in its class.Typical DDS generator has a higher noise floor and greater

harmonics.Trueform technology significantly improves jitter performance.

Trueform technology.Traditional DDS technology.

If your generator is introducing spurious signals or harmonics, you’ll have a hard time producing reliable designs. To be successful, you need to test with clean, precise, low-noise signals. Keysight 33500B Series waveform generators offer the highest signal fidelity so you can generate the exact waveforms you need for your most challenging measurements. You can be confident you are seeing your design’s characteristics, not your waveform generator’s, in your measurements.

Reproduce lower-voltage output signals Today’s ultra-low-power products such as pacemakers, hearing aids

and remote sensors use very low voltages. The 33500B Series lets you create signals as low as 1 mVpp. That’s 10x better amplitude resolution than typical waveform generators offer.Full bandwidth modulation sources Eliminate the need for an external modulation source. The 33500B

Series has a modulation frequency up to the frequency of the waveform being modulated. Existing DDS-based generators have a much lower internal modulation frequency. Now you can create your complex signals all within a single generator.

Highest amplitude resolution

The 33500B Series’ 16 bits of resolution is 4x that of most waveform generators. You can make output changes all the way down to

1 μV—exactly what you need for testing today’s low-voltage circuits

Full bandwidth pulses

Create pulses up to 30 MHz with the 33500B Series. Most DDS-based generators offer reduced bandwidth when generating pulses. With a broader operating range, you have the frequency you need for

a wider range of applications.
