Based on NI 9234 and USB-type, the portable vibrating modal analysis system is constituted by CompactDAQ. With the cabinet and portable characteristics, the system can help the users to finish dynamic testing task rapidly and accurately. It is mainly used to test small-size structure with a lot of function modules, including: data acquisition, signal processing, frequency response function estimate, three-dimensional modeling, ODS, modal analysis, analysis of mode shape as well as report generation. We believe that with portable modal analysis system, you will find your testing task much more easier.
