NetdB dBFA Software Suite
Easy Tools for NVH Analysis
Easy tool for NVH analysis
dBFA Suite: Your "passe-partout" for the NVH
world!
A "real" companion for any
01dB-Metravib supported hardware platforms, performing
real time and off-line analysis of noise and vibration
signals.Taking advantage of the long experience acquired
by 01dB-Metravib (dBFA 1.0 was released in 1990!), dBFA
Software suite, including Recording and Real-Time
Analysis as well as numerous off-line standard and
advanced post-processing functions, provides the ideal
solution to Industrial Engineering offices, R&D
departments, technical centers and laboratories..
Multi-platform real time recording and analysis for
daily operations?
That's what dBFA Software Suite is offering you and even
more!

Several 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. |
