Packages and Modules

- dBFA Recorder-PostProcessing : the basic package to record time domain signal, monitoring FFT and 1/3 octave and to post-process these data. It includes the Recorder and standard Post-Processing modules. dBFA Recorder-Analyzer-PostProcessing : the advanced package included the dBFA Recorder-PostProcessing features with more simultaneous real time processing (FFT, FRF, 1/nth octave, tacho process, overall levels, real time statistics, calculations vs time and rpm, ...)., more display capabilities. It includes the Recorder, Analyzer and standard Post-Processing modules
To one of these two packages, you can add some options :
Real Time options
- Sound Intensity Option: sound power / intensity process according to ISO9614 standards.
- Transcient/Impact: OptionFRF triggered with path definition for transient and impact testing applications. Coordinates management, user defined windowing, Me'scope format export... (requires Recorder-Analyzer-PostProcessing package).
- Order tracking Option: Order Analysis and Order Tracking in Real Time and post-processing for Rotating machine applications. (requires Recorder-Analyzer-PostProcessing package).
- Reporting Option: Useful to enhance productivity. It's possible to get a test report immediately at the end of your acquisition in Analyzer mode. The feature is also available in post-processing mode.
- RT Automation Option. Useful to enhance productivity to perform sequential tests.
