Software platform – NVGate

NVGate is the OROS software platform. It manages instruments’ setup and signal analysis in both real-time and post-processing. NVGate is the link between data acquisition and analysis results. It gathers the basis of noise & vibration measurement backbone with front-end setup, signal processing, calibrations, transducers’ database, live results graphs, reports and measurement automation tools. It holds natively the Teamwork software technology that boost efficiency, security and quality of measurements.

Focus on signals, anytime, anywhere – Monitor

The monitor is an analyzer into the analyzer. It allows hot swapping to any inputs to monitor with live processing:

  • Time-levels (DC RMS, Peak, Pk-Pk) with advanced triggering
  • Time series (triggers-block)
  • Narrow band spectra advanced triggering capabilities

The monitor improves checking the instrumentation, the quality of signal and the measurements reliability.

Up to 4 additional analysis channels run on a dedicated DSP. It enables using the monitor at anytime without disturbing the measurement process.

Catch the right signal - Recorder

The NVGate recorder offers advanced modes to help recording the right data and reducing size. Raw data security backup, signal acquisition with spectral/levels monitoring and transient capture are easily handled:

 

  • On-line recording is managed by a dedicated DSP in the instrument, enabling a gap-free recording simultaneously with the process of other analysis modes
  • Recorded files are secured with redundant saves during the acquisition
  • In addition to the classical manual Start/Stop and fixed duration acquisitions, the Time-to-Stop records physically a continuously buffered period up to GB of data. Using this mode with a trigger on event signal catch the pre-event raw data rather than recording during hours or days.
  • To avoid the boring manipulation of large raw data files, multiple sampling rates can be used simultaneously, 2 user defines (ex acceleration and noise), 1 for parametric inputs (10 Hz) and 1 high for oversampled triggers (6,4 MHz)

Result history - Waterfall and profiles

Spectra, levels, orders and trigger blocks are stacked providing flexible 3D waterfall and powerful 2D profiles. Adapted graphs color-spectrogram, Bode plots, order tracking trend are plotted vs time, RPM, power, torque or any levels and parametric inputs. Adapted cursors and markers offer powerful inspection/comparison tools with cursors linked between multiple graphs.

 

Sections extract orders frequency bands, max order from colormaps/waterfall results. Profiles are automatically averaged to provide representative results from multi-runs.
