The channel module and DSP card provide multichannel signal conditioning, filtering, digitization, and high-speed FFT measurements in a package that measures 9.5 x 7.25 x 1.5 inches and weighs only 2.5 pounds. An optional external rechargeable battery pack allows BOBCAT to troubleshoot problems in the field.

STARModal integrates all the structural analysis capabilities that you require - from time domain animation and operating deflection shape analysis to advanced modal analysis. Flexible animation capabilities let you clearly visualize structural vibration behavior and identify problems.

Featuring intuitive pull-down menus and the point-and-click interface of the Microsoft^â Windows 95^TM operating environment, the BOBCAT user interface minimizes training time and speeds test and analysis operations.

High Performance, AccurateData Acquisition
The BOBCAT System offers FFT analysis (DC to 20 kHz) on all 8 input channels and an output channel for random, discrete sine, and discrete sine-on-random signals. Each input channel has a dedicated 16-bit ADC with programmable voltage ranges and anti-alias filter. An 80 dB signal-to-noise-ratio and selectable AC, DC, Differential, or ICP input guarantee accurate data. BOBCAT supports data streaming to the PC host disk at a 12 kHz sample rate (5 kHz analysis) for all 8 input channels simultaneously.

Special Features for Modal Data Acquisition
Designed to do modal testing, BOBCAT provides full structural analysis capability. Variable spectral resolution, comprehensive measurement functions, and multiple display windows simplify data acquisition. Flexible windowing and triggering functions provide the versatility required for accurate modal measurements on all types of structures.

Special features help ensure that you get the data you need on the first try. These features include automatic sample rejection on voltage overload or impact hammer double hits, manual sample rejection, and audible armed/acquired trigger status alerts.

Seamless Data Storage Interface to STARModal
Storing data and coordinate information is as simple as clicking the 'STAR Save' toolbar button. All data is stored in binary format so that you can access data from STARModal quickly and efficiently. To speed data acquisition, you can set up to automatically increment modal coordinates after each measurement.

Comprehensive Structural Analysis Capabilities
STARModal offers a comprehensive set of analysis and animated display capabilities to fully characterize a structure's dynamic response. A wide variety of curve fitters, from simple peak pickers to highly sophisticated multireference algorithms, allow you to obtain accurate results quickly. And you can easily verify results by using FRF synthesis and Modal Assurance Criteria.

Flexible structural modification options allow you to simulate fixes analytically. You can also simulate structural responses to real-world forces. To view the total system response, time-domain analysis animates time history data directly. Operating deflection shapes allow you to determine a structure's motion at a specific operating speed or frequency.

Beyond Modal Analysis
You can extend your data analysis capabilities by using supplied DLL libraries to interface to applications such as MATLAB^TM and EXCEL^TM. For acoustic analysis, STARAcoustics^TM allows you to identify noise sources and quantify sound power.
