BK Connect Reflex Measurements – Type 8729-A & 8729-B

BK Connect Reflex™ real‐time measurements are designed to take advantage of Brüel & Kjær’s unique coverage of the complete measurement chain, from transducers and front‐end hardware to data acquisition, analysis and reporting. The emphasis is on scalability, from small (single‐module) systems to large (multi-module) systems, and high productivity in the traditionally most time‐consuming aspects of data measurement:

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

All measurements are directly accessible by the BK Connect Reflex post‐processing applications; BK Connect Reflex Core for general purpose post‐processing, BK Connect Reflex Modal Analysis for modal parameter estimation and BK Connect Reflex Correlation Analysis for test‐FEA model correlation.

Features of Classical Modal Analysis


  • Modal data acquisition and validation
  • Impact hammer FRF measurements
  • Single- or multi-shaker FRF measurements
  • Mechanical impedance or mobility measurements
  • Time data recording during measurements
  • Integrated solution from structural measurements to FEM correlation with BK Connect Reflex Modal Analysis Types 8720 and 8721 and BK Connect Reflex Correlation Analysis Type 8722


  • Geometry-guided modal data acquisition using BK Connect Reflex Modal Analysis or BK Connect Reflex Core
  • Interactive graphical representation of the front-end hardware using the Hardware Matrix, with coloured light rings to indicate channel status, for example, overloads, just as on the actual LAN-XI hardware
  • Easy management and overview of large channel counts
  • Automatic detection of TEDS-enabled transducers as well as auto-import of TEDS data
  • Integrated transducer manager and database
