Highland Technology Introduces New VME Arbitrary Waveform Generator
Model V375 Adds Greater Versatility, Extended Bandwidth

SAN FRANCISCO, California, July 14, 2003 -- Highland Technology, Inc., today announced the release of their Model V375 4-Channel VME Arbitrary Waveform Generator. The V375 builds on the success of its predecessor, the Model V370, by extending the output bandwidth to 300 kHz and adding four inputs for user waveforms to sum into the channel outputs. A new burst mode allows software or external input to trigger generation of one or more waveform cycles.

"Our VME arbs form the foundation of multi-million dollar test programs at major aircraft engine and power systems manufacturers," said company president John Larkin. "The V375 is a direct result of customer requests for new features to support their new product development."

The V375 is designed with features that make it ideal for simulating sensor signals from complex rotating machines. An onboard microprocessor executes macro commands that simplify generation of pure and distorted polyphase AC waveforms, with amplitude, frequency, phase, and distortion components smoothly variable in real time. Other macros create complex pulse trains with real time control of pulse positions, amplitudes, and missing pulses.

The module provides four memory-table waveform generators with 16-bit amplitude resolution and from 64 to 65,536 points per waveform. Four independent direct digital synthesizer (DDS) frequency sources step through the memory table at rates up to 15 MHz. The DDS frequencies are variable in real time in milli-Hertz increments, and per-channel divisors allow simulation of fractional "gear-ratio" waveforms. A synchronization capability links up to 64 channels across multiple modules.

Each channel output features an analog summing stage that can mix up to four generated waveforms plus one user waveform per channel. And, a programmable gain stage on each output allows the user to dynamically scale the output waveform amplitude without reloading the memory table.

Pricing for the Model V375 VME Arbitrary Waveform Generator starts at $4750.
