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.

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 pane …… 此处隐藏：16531字，全部文档内容请下载后查看。喜欢就下载吧 ……
