trueform technology
Generate trueform arbitrary waveforms
with less jitter, more idelity and greater resolution
Over the past two decades, 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 its limitations. Engineers with exacting
requirements have had to either work around the compromised per-
formance or spend up to 5 times more for a high-end, point-per-clock
waveform generator.
Agilent’s Trueform technology offers an alternative that blends
the best of DDS and point-per-clock architectures, giving you the ben-
efits 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.
The table below highlights the revolutionary capabilities of
Trueform technology.
