Agilent Technologies, Santa Clara, CA, has introduced the 33500B Series waveform generators. The eight one- and two-channel models, which generate waveforms up to 30 MHz, incorporate Trueform signal-generation technology, which enables the units to generate a range of signals for measurements required when designing electronic devices. The generators provide low jitter and total harmonic distortion, enabling engineers to place edges more accurately and reduce timing errors. Total harmonic distortion is less than 0.04 percent, and non-harmonic spurs are less than 75 dBc. The instruments features 16 bits of resolution for output changes down to 1 uV. Software upgrades expand the instruments’ capabilities to increase bandwidth and add true point-by-point arbitrary waveforms and deeper waveform memory. Users can add noise to signals for margin and distortion testing using a single channel. On a two-channel model, engineers can sum and combine up to four signals. Users can also create multiple configured waveforms with several common segments.
