Modal Test and Analysis
Bobcat Signal Analyzer
The most cost-effective, accurate, powerful entry into Structural Analysis available today.
CATS Modal
CATS Modal integrates all the functionality of STAR Modal into our Computer-Aided-Test-Suite of applications, combining acquisition with analysis for unparalled power and efficiency.
Data Acquisition
Integrated data acquisition makes acquiring and managing large sets of modal data easier than ever. Automated management of measurement DOF simplifies data acquisition for multiple data sets and reduces test time. A built-in signal generator provides user-specified excitation type (random, sine, chirp, burst random, user-defined) and amplitude control.Upgrading to Premier Modal Data Acquisition adds the ability to acquire multiple-input, multiple-output (MIMO) modal data.
For acquisition of long time history events, the optional removable SCSI throughput disk provides simultaneous acquisition of time data to disk for up to 128 input channels at up to 51.2 kHz sample rate per channel.
Data Analysis
By integrating data acquisition with analysis, CATS Modal simplifies the data acquisition task and provides the same powerful function data viewing capability for both data acquisition and analysis. Function data displays include:
· Multiple graphs per page
· Overlay up to 6 data traces per graph
· Multiple page reports
· Optional 3D waterfall displays
· nth octave analysis
The optional Virtual Calculator can even provide math processing of live data streams and stored data files for complete flexibility in signal processing.Optional modules for Transient Analysis (SRS) and Swept Sine Analysis give CATS extremely powerful and versatile signal analysis capabilities.
STAR Modal is a comprehensive structural analysis package for Microsoft Windows TM (Windows 7 and Windows 8.1). Bringing together the latest technology in structural testing, user interfaces and graphics, you can test, analyze and present with confidence and ease.
Each of its dynamic analysis methods illuminates a specific aspect of the structures dynamic behaviour. Built-in animation capabilities let you clearly visualize structural behaviour and identify problems.

Operating Deflection Shape Analysis: View a Structure's Motion at a Specific Operating Speed or Frequency...
Structural motion caused by external forces, gear chatter, imbalance, loose mounting, and other factors is easily analyzed and animated.
Modal Analysis: Analyze and Solve Structural Dynamics Problems...
Fully analyzing and solving structural dynamics problems require the power of modal analysis, which separates mode shapes from the overall dynamic response of the structure. The robust modal analysis features of the STAR6 System™ reflect over 15 years of technological leadership.
Advanced Curve Fitting: Utilize multiple references to ensure accurate estimation of your modal parameters...
The Advanced Curve Fitter of the STAR6 System™ is a special hybrid algorithm that uses Least Squares Complex Exponential (LSCE) and polynomial techniques to accurately estimate modal parameters on complex or redundant data sets.
Time Domain Analysis: See How a Structure Moves Over Time...
Animation of time history data shows the structure's actual movement over a measured time period. This is often the first step in solving vibration or motion related problems.
Evaluating your Results: There are a number of easy to use tools to check the quality of your analysis and help you better understand the results...
