ME'scope Application Note 54
Rapid Impact Test™ Using 2-Channel Data Acquisition
One of the limitations of conventional modal testing using a roving impact hammer is that the reference sensor (usually an accelerometer) must remain fixed throughout the test. Since the accelerometer must be connected by a wire to the data acquisition system. a very long wire may be required when testing a large structure. Furthermore, better quality signals are possible if each impact force is applied closer to the response accelerometer. Because it does not require a fixed reference sensor throughout the test, a Rapid Impact Test is faster and easier to use on any size structure.

This App Note contains a downloadable ME'scope project with Hotkeys that walk you through the Rapid Impact Test™. Check it out!

ME'scope ODS and Modal Training Course
A couple seats remain for our most popular hands-on ME'scope ODS and Modal Analysis course, April 23-26th 2019. Join us at the Vibrant Headquarters for this 3-day training seminar in Centennial, Colorado just outside of Denver.

This course takes a fundamental approach is understanding the details of ODS (Operating Deflection Shape) and Modal Analysis.  Many training courses spend 2-3 days discussing differential equations, Fourier Transforms, matrix mathematics, etc., etc. This course is different. We concentrate on fundamental dynamics relationships, simple guidelines and emphasize the underlying concepts with numerous case histories and visual animations. We believe that to do their job well, the vibration analyst needs to understand the basics of dynamic motion.

The ME’scope training portion of the course is built around a detailed project workbook (The ME'scope Workbook).  Each workbook project is presented as a step-by-step series of instructions using ME'scope. The various exercises will acquaint a new or novice user with the many functions of ME'scope.  


Course Date: April 23-26th 2019
Course Tuition: $1,695.00
Instructor: Dan Ambre, president of Full Spectrum Diagnostics, and Vibrant staff.
Laptop PC computers are required
ME'scope Visual Rapid Test™
Visual Rapid Test™
Vibrant has introduced a new ME’scope package called Visual Rapid Test™. This new method is faster, easier, more flexible, and less costly to implement than conventional ODS or modal testing methods. Since only the structural responses are acquired, it can be used for ODS testing of operating machinery, or for modal testing using an impactor or multiple shakers.
This package employs a new testing method called "TRN Chain testing". TRN Chain testing only requires two vibration response sensors and as little as a 2-channel acquisition hardware system. Either sensor or both sensors can be moved between acquisitions, thus forming a chain of Transmissibility measurements called a TRN chain. The TRN chain preserves the magnitude & phase relationship between pairs of structural responses in the chain.
After a chain has been acquired, it can be seeded with either an Auto spectrum, Cross spectrum, Fourier spectrum, or FRF to yield a single-reference set of measurements. These measurements can then be used to extract ODS’s and mode shapes of the test article.

Pricing is only $5995 for up to 8 channels. Contact sales@vibetech.com or your local reseller for more information.
