Measurement Management and Reporting
Control Panel
The Project Manager gathers signals, measurements’ results and
the analyzer’s set up parameters for easy referra on future projects
or in the review of recorded data.
The Measurement Editor formats the results into electronic reports
labeled by markers and cursors. Measurements are then easy to
recall and compare, even with live data.
The Reporter refreshes graphs, data, settings, meta-data and tables
into MS Office documents. A simple drag & drop makes the document
a report template easily updatable with current or saved measurement
Rotating Analysis, from Acceptance Tests
Whatever the machine
type: a high speed
turbine, a compressor,
a transmission or a
slow speed engine,
OROS analyzers
provide all the tools for
rotating analysis from
acceptance tests to
Rotating Speed Measurements
OROS 3-Series analyzers feature flexible and accurate shaft speed measurement tools.
Tachometer signals are over-sampled to ensure accurate rotating speed and phase.
Signals can be adjusted for better pulse detection using filters, holdoff and hystersis.
When a second gear shaft is not accessible, fractional tachometer computation allows
you to calculate its rotating speed and related order analysis.
External Trigger Channels
■ 2 tachometer inputs are standard (6 maximum)
■ High sampling rate of 6.5 MHz (< 152 ns resolution)
to allow a precise measurement of the phase.
Integrated Frequency to Voltage Converter
The torsional module utilizes an integrated software
frequency to voltage converter based on the signals
captured in the external synch inputs.
Tachometer Math Editor for CVT
Real-time calculation of the rotating speed of a
Continuously Variable Transmission (CVT) custom formula
based on 2 tachometer inputs.
Computation of Gear Elements Rotating Speed
The fractional tachometer computes the speed
and phase of the output shaft (based on one
tachometer and the gear ratio).
Envelope Demodulation
Damaged roller bearings are common sources of vibration.
Their vibration signal, measured with an accelerometer,
allows you to determine the mechanical failures of the
bearing. Envelope demodulation, a part of FFT-Diag
module, effectively provides this function.
Constant Band Tracking
Gearboxes’ generate modulated and often buried noise
and vibration orders, which are not easy to extract. The
CBT helps the user acquire these orders for his analysis.
Synchronous Order Analysis
Order tracking is most often used when the rotor speed
varies: transient analysis. Obtaining the correct results from
run-up/down requires specific signal processing techniques.
The software module uses a resampled angular domain
signal as input data. It extracts complex orders (phase
and amplitude) acquired from fast run-up/down.

software using the external synch channels as inputs. It is used for the
measurement of torsional vibration and twist. The Instantaneous angular
Velocity Converter (IVC) software option provides instantaneous angular
velocity signal for the analysis plug-ins.
Integrated Frequency to Voltage converter
Shaft View: instantaneous angular signal for single or multiple revolutions
Cross Phase Tracking: the cross-phase order by order between
a reference channel and other speed signals. It is useful for the
identification of torsional resonances at specific orders and the
evaluation of their amplitudes

Waterfall, the Synchronized Data Buffer
This specific plug-in collects and synchronizes all data coming from
the analyzers data stack. Results are arranged based on a choice of
references for the Z Axis (RPM, Time and levels) and represented in 3D
or profile views. Identifying the critical analysis item, such as speed, is
then much easier as its effects are seen in different dimensions: order,
frequency, octave. The section manager of the waterfall plug-in feature
orders, overall, constant frequencies and spectra extraction in one click.
Structural Analysis, from Acquisition…
Structural analysis
is a powerful tool
for understanding
the behavior of
industrial machinery
and their supporting
structures. It is used
in maintenance,
prototype validation
and mechanical
design as well as field
Good structural
analysis starts with
good data. For that
reason, all the tools for
efficient and accurate
acquisition have been
integrated into our
structural solutions.
Structural Acquisition With NVGate
With its dedicated structural mode, the FFT plug-in offers a comprehensive tool panel for
FRF acquisition. Whatever the method used, impact hammer or shaker excitation, FRFs
are confidently acquired.
■ Check the validity of the acquisition thanks to different displays and their preview:
- Frequency Response Function
- Coherence
- Trigger blocks
- Averaged results
■ Adjust the settings using an appropriate weighted window if necessary:
uniform, force/response, hanning…
■ Accept /reject the impact hammer measurement after validity checking
■ Hammer impact auto-range
■ Define the measurement sets in advance and use the node path sequencer to track
all measurement points
■ Export the FRF in Universal File Format and MATLAB® format
For exciting a large structure, up to 6 shakers can receive signals
from the generator outputs of the analyzer. In order to fit the wide
range of potential cases, a large series of excitation signal such
as swept sine, chirp, random, etc. can be simultaneously
generated. Any channel can be set as the reference which
generates a multiple reference FRF and cross spectrum matrix.
VibeMaster, Large Channel Count System
Large structures require a high number of input channels. With
VibeMaster, multiple OROS analyzers can be cascaded to
increase the total channel count. This solution offers the same
acquisition, recording and analysis capabilities as 3-Series analyzers
on wider scale applications.

DSP-Based Architecture
The Need for Real-Time
Every part of the signal contains important signatures
hidden by non real-time analyses. Live synchronous order,
1/n octave and filtering are not possible without gap free
analysis capability. Real-time analysis helps getting actual
data on-line.
Thanks to this DPS-based architecture, OROS 3-Series
analyzers provide the same measurement and analysis
performance whatever the number of channels or
DSP is Your Data Security Passport
Many dynamic signal analyzers get their signal processing
power from the PC’s processor(s). The undeterministic
behavior of PC operating systems (not real-time) may
rapidly lead to loss of samples while the duty increases.
Our DSPs (Digital Signal Processor) are designed to
offer 100% controlled computation. They allow to know
the amount of analysis capabilities before starting the
