Trueform Technology
Generate true point-by-point arbitrary waveforms with less jitter, more delity
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.
