Impact Testing

Impact testing includes useful tools like the selection of a roving hammer or transducer, selection of data points/nodes, double impact detection and rejection, definition of force and exponential window and a user-definable display configuration as a visual measurement feedback.
The combination of automatic DOF/node scheduling, automatic rejection of invalid measurements and automatic saving of data after a user-defined interval virtually eliminates all keyboard interaction. This is helpful for impact testing on large structures or at locations that are difficult to access.

Key Features

• Unlimited and freely definable list of user- specific header information (metadata) for annotation,
  data retrieval, sorting and reporting
• Simple parameter entry for the channels in tables including engineering units, transducer
  calibration data and inputs
• Channel type: excitation, response, inactive; DC or AC coupled; input range, offset, pregain
• Channel input: V, ICP, Charge
• Enter transducer calibration data or import from Excel
• Roving hammer or roving transducer mode
• Easy selection of measurement points (nodes) and directions
• Acquisition setup: sample rate or useful bandwidth, blocksize, arming
• Level trigger and pretrigger view
• Data processing/data storage: (windowed) time record, spectrum, PSD, average PSD,
  cross-PSD, average cross-PSD, FRF, coherence; linear averaging
• Windows: uniform, force, exponential; force width and exponential end in %
• Automatic detection and rejection of double impact measurements
• Automatic, hands-off stepping through measurement points (nodes) and storage of
  averaged results during acquisition
• User-definable displays for impact pulse, PSD, FRF/Coherence etc.
• Save and recall measurement and display setups
