Agilent waveform generator has low jitter and low distortion
Agilent Technologies has introduced a range of 30MHz waveform generators which are designed for very low jitter and low harmonic distortion.
The total harmonic distortion is less than 0.04% and non-harmonic spurs are less than 75dBc.
The 33500B series generators offer 8.4ns rise and fall times. With 16 bits of resolution the instrument can be used to make output changes down to 1µV.
Over the past two decades, direct digital synthesis has been the waveform-generation technology of choice in function generators and economical arbitrary waveform generators.
Waveform generators built with DDS offer good frequency resolution, convenient custom waveforms and a low price.
However, DDS has intrinsic 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 generators incorporate the supplier’s Trueform technology which uses a new type of digital sampling technique.
This allows engineers to add noise to signals for margin and distortion testing using only a single channel. On a two-channel model, engineers can sum and combine up to four signals.
It is also possible to adjust the bandwidth of the built-in noise generator to control the frequency content of their signals.
