This PULSE Reflex software controls modal measurements, helping you set up, acquire and validate data for subsequent post-processing analysis using the PULSE Reflex suite of programs. Because the PULSE Reflex user-interface is intuitive and consistent, this is the ideal measurement software for use with PULSE Reflex Modal Analysis and for integration of test results with finite element analysis (FEA) using PULSE Reflex Correlation Analysis.

The software emphasizes scalability and high productivity in the most time-consuming aspects of structural measurement:

  • Setting up transducers, channel tables, excitation and analysis parameters
  • Post-processing, displaying and reporting results


Fast setup and acquisition of modal data using an impact hammer, such as troubleshooting of automotive vehicle components

  • Advanced modal measurements and non-linear studies on complex structures such as satellites
  • Modal surveys using multiple exciters for tests of large structures such as aircraft during ground vibration testing (GVT)


In the software, the data acquisition hardware is displayed in an interactive graphic visualization that gives simple channel selection and transducer verification, and a clear overview of any potential issues such as transducer overloads and cable breaks. For larger setups, channels can be listed and sorted according to status for quick resolution of issues. The user is guided step-by-step through the test with visual and audible feedback, enabling less expert users to routinely perform modal test measurements. Expert users will appreciate the high level of flexibility in test setup and execution as well as the strong interface to finite element (FE) models for test planning and validation.


The graphical display of the test object’s geometry lets you interact with it to make various tasks intuitive. Advanced geometry creation tools allow you to create a test geometry from scratch, but you can also import an FE model and decimate it down to a test model either manually or using dedicated tools. With roving accelerometer testing, the geometry display clearly indicates degrees of freedom (DOFs) to measure. The geometry model also allows easy quality-checks on measurement results, using animations of the test geometry such as frequency response functions (FRFs).
