Shaker Performance Article by George Lang and Dave Snyder Published in Sound & Vibration Magazine

San Jose, CA - 13 November, 2001 - The October issue of Sound & Vibration magazine contains an article, Understanding the Physics of Electrodynamic Shaker Performance, by George Lang and Dave Snyder of Data Physics. Shaker performance is neither terribly complicated nor quite as straightforward as a glance at shaker specifications might make it seem. There are many variables which affect the way a given shaker will perform with a given load. Lang and Snyder step the reader through what matters and why. In conjunction with this article, Data Physics has added a worksheet on the www.dataphysics.com web site to evaluate the performance of any shaker, given certain characteristics easily found in the shaker specifications.

Data Physics Introduces Sound Quality

San Jose, CA - 25 October, 2001 - Data Physics, long known for its vibration expertise, adds to its capabilities in acoustics with the introduction of DP Sound Quality - Loudness. The Loudness option for SignalCalc analyzers allows application of a variety of Sound Quality metrics on files or on live data, including time-varying loudness (Zwicker), sharpness, roughness, fluctuation strength and unbiased annoyance. Waterfall plots with slices and records simplify the task of understanding the sounds being measured, and easy annotation and plotting smooth the way for documenting tests. More info

2002 Class Schedule Announced

San Jose, CA - 18 October, 2001 - Data Physics has set the dates for vibration training courses in 2002. These are completely revamped courses that take advantage of Data Physics' new Mentor training system for an unprecedented level of guided hands-on live measurement experience. Mentor hardware is designed to simulate the sort of reasonably complex system that provides enough challenge to require good measurement technique, but not so much as to overwhelm the student. Mentor software serves as a lab assistant that never loses patience and knows when to stop talking. Register now

Data Physics Shakers, For a Complete Vibration Test System

San Jose, CA --13 September, 2001--Data Physics introduces its own line of shakers. Data Physics provides a broad range of electrodynamic shaker systems for use with SignalStar Vibration Controllers and SignalCalc Analyzers. Four design groups are offered: small permanent magnet shakers (2 to 100 Lbf), mid-range shakers (150 to 1800 Lbf), large systems (2400 to 12000 Lbf) and modal shakers (17 to 600 Lbf) optimized for "stinger" drive. A full range of accessories, power amplifiers, tables and trunnions is also available. More about shakers...

Data Physics Releases Version 5.2.0 Software for Vibration Controllers

San Jose, CA August 29, 2001 Data Physics announces the release of software version 5.2.0 for SignalStar and SignalCalc Vibration Controllers. This software release includes both enhancements to the standard product and new features.

Network Monitoring is a new option that allows other computers to observe measurements on the controller, even while tests are running. Review, Export and Test setup may now be performed on any computer – even when that computer is not connected to controller hardware. The Transient package has been made easier to use for Earthquake (Bellcore) tests. A new time domain control algorithm has been added to Shock and Transient tests for improved performance when the system behavior is non-linear.
