Compatibility: Same as V12.00.

One click update of the license keys

If you are now using NVGate version 11 or a previous version, you will need to update the license keys of your analyzer and USB dongle in order to run the NVGate version 12.10 that you have installed on your PC.

The NVGate connection window has been enhanced in version 12.10 to quickly update the license keys.

How to proceed?

  • 1) Select the item (analyzer or dongle) for which you want to update the license keys.
  • 2) Select the .ZIP archive containing your new license key files (as sent by mail by customer care team or your local distributor).

The license key files will be automatically copied in the NVGate installation folder and the keys of your analyzer and USB dongle will be encrypted.

  • 3) The firmware update will be automatically performed.

Key update process

Seamless transition from recording to post analysis

After recording a signal and computing some results with the NVGate plug-ins (FFT, SOA, OCT) you may need to post-analyze the recorded signal to change a few analysis settings or compute additional results using the same plug-ins.

With NVGate 12.10, it is now possible to post-analyze a signal:

  • Directly using the same setup as the one used during the recording. If required, modifications to the setup can be completed in an additional step.

In that case, after loading the record setup the same results will be computed and / or displayed as during the acquisition. It is then possible to change the analysis settings, add or remove results and modify the layouts.

Note: 'if the record setup contains virtual inputs, torsional channels, CAN or DC channels, the connection of these channels to the plug-ins will be reset.

  • or start from scratch on a new default setup.

In that case, all the tracks connection to the plug-ins will be reset.

How to proceed?

To post-analyze a signal and choose to keep the record setup or use a new setup, you can either:

  • Select the signal from the Post Analysis menu and select the Post-analyze option as follows:

Release note NVGate V12 10 14.png

Selecting a signal to be post analyzed from the Select Signal window


  • Or right click on the signal in the NVGate Workspace and select the Post-analyze option:

One step further for properties management

Properties are a great feature of the Teamwork platform which allow users to associate contextual information to their measurement data and setups (properties are applied when saving a project, a setup or a measurement).

Without such a tool, the natural tendency would be to insert this information in the titles of the measurements making the users life difficult when it is time to sort and find relevant data.

New key features are now available in the Properties Manager of NVGate 12.10 which allow a smooth experience of the Dataset management.

Filling in properties content from a drop down list

The user is given the possibility to fill in the content of a property from a drop-down list of predefined choices as shown in the window below:

Release note NVGate V12 10 16.png

Filling in a predefined choice for a property (when for example creating a new project)

How to proceed?

1. Start the properties manager window for the "Home ribbon"

Release note NVGate V12 10 17.png

Starting the properties manager window

2. After selecting a property, the property type can be selected. Three choices are available:

Free text: The user can enter any text freely when filling the property information.

List (restricted) (New in V12.10)

Fill-in the List items in the Properties manager. Then, when saving a project, a measurement or a setup the user will be able to select the item from a combo list as shown below.

List (New in V12.10):

This option is a mix of the "Free text" and "List (restricted)" option. During a save (measurement, setup or project), the list is proposed as a combo but free text still can be entered. For that the list items should be entered in the properties manager for the selected property. In this case, the property will be given the free text content but the list will not be populated with this new entry. If this is required, the list of that property can be modified in the properties manager.

Deleting existing properties
Release note NVGate V12 10 21.png

Deleting existing properties

The selected properties will be deleted from the database. The multi-selection enables to delete several properties at once.

Once deleted, the properties can still be shown using the "Show deleted properties" (Option accessible from the delete button using the down arrow. The property can be recovered by modifying the behavior to something other than "deleted" as shown from the window below.

Release note NVGate V12 10 22.png

Show deleted properties

Tips: 'How to completely reset your properties base? To achieve this you must delete the files "userPropertiesLibrary" and "userPropertyPolicies" which can be found at this location : C:\Users\Name\AppData\Local\OROS\NVGate

Managing the incoming properties

This feature allows a user to choose how to deal with properties coming from imported NVGate projects, measurements and models (after an import or a collate for example).

You can select what will happen to a property when the import occurs. The behavior is adjusted after pressing the button "Incoming …"

2 main choices are available: Import or Ignore

  • Import: When this behavior is selected, the user needs to select the following settings:
  • "behavior": apply to a new project, to a measurement, to a model, or don’t apply it (Nothing).
  • "suggest": empty, same as previous, same as today.

To update the properties for a team who use several PCs, select this option, then import a project, measurement, models on the PCs. The new properties will be including on the new PC, including combo list.

  • Ignore: When this behavior is selected, the property will actually take the status deleted right at the import level.

NVGate V12.00

The 12th major version of NVGate is available from January 2020. This major release of the OROS Teamwork software platform welcomes several new analysis modules and brings significative performance improvements.

This release note describes the content of version 12.00, with operating details.


NVGate V12.00 is compatible with all OROS instruments that have not been discontinued. Depending on the hardware options and version, some instrument features may or may not be available. This release is compatible with Windows 7, 8.1 and 10 versions.


The following features have been added in this NVGate release:

New Modules

NVGate V12.00 supports the operations of 3 new modules which work within the platform.

MODS support

This latest release is a part of the Mobile DAQ System introduced in 2019. It provides all the necessary features to work with the OR10 DAQ for both setup preparation and post-processing. It integrates the OROS DataSet management allowing high security and visibility to OR10 DAQ data that are comprehensively integrated in the Teamwork data.

NVGate V12.00 allows running any module of the OROS software suit on the OR10 DAQ in both on-line and post-processing modes.

EV/HV NVH testing solution

Developed in collaboration with EOMYS, a specialist of electromagnetic noise &vibration, the EV/HV NVH module enriches the platform with a toolset related to electric motors and their associated power electronics.

Integrated in NVGate as a ribbon, the EV/HV module covers the full process from motor typology and characteristics to the identification of electric noise sources. Based on motor geometry, electric markers are calculated and positioned on the displays. Then, the most contributing electric wavenumbers can be determined based on the calculation of the spatiograms.

The Monitoring solution
Release note NVGate V12 10 03.png

Machinery noise and vibration levels can often increase rapidly and unexpectedly: in particular, after a recent installation or a maintenance operation. At that stage the machine may need to be carefully monitored for a few weeks or even months. This monitoring must be autonomous when the machine is located on a remote site where it is impossible to wait for an event to occur.

The Monitoring solution extracts results from the NVGate analyses at a predefine rate while checking continuously the analyzer and software operation. A reboot box is available to start and stop the analyzer remotely.

NVGate Improvements

NVGate V12.00 comes with important improvements in ergonomics, performances and stability.

New functions
  • Select number of decimal digits to be displayed.
  • Edit DOF values in existing measurements.
  • Calibration module: last calibrator reference memorized and visible measured level.
  • Scaling all graphs at once in multi-graph windows.
  • Generic roller bearing kinematic marker database.
  • Increased the number of layouts in RAM memory.
  • Window color changeable by macro:

  • Optimized measurements in test center with operators’ conducted acquisition followed by experts’ post-processing
Release note NVGate V12 10 32.png
  • Light travelling for consulting
Release note NVGate V12 10 33.png
  • Measuring in uncomfortable situations (sole driver, elevator, risk areas).

The System is made of 3 parts:

Release note NVGate V12 10 08.png

The OR10 Mobile instrument. This device features the exact metrology of Teamwork instruments with 8 ch. 2 Ext. Sync (Tach), CAN bus and GPS. Its large autonomy allows working more than ½ day before recharging the battery.

  • NVGo: The Android App is used to select acquisition setup, monitor and inform measurements. NVGo perfectly matches both of the above situations.
  • NVGate V12.00 runs the OR10 as a front-end which allows its software be updated. NVGate is also used to add setups (Templates) to the OR10 as well as recovering measurements from it.

These 3 items work together, providing the best efficiency at each step of the measurement process: Preparation, setup, information, transfer, selection and post-process.


Operating NVGate with the OR10 as a front-end is exactly the same as with the other instrument of the OROS range. Some performance or real-time limitations may occur with demanding configurations, especially when the PC is connected to OR10 through WiFi.

See details in the [M002-177-4] MODS User’s manual available from the Manuals directory in the NVGate V12.00 install directory.


OR10 holds the licenses for standalone, NVGo and NVGate instrument locked analyses. All licenses are optional. The minimum set to measure and recover the signal is:

  • OR10-SAP-I
OR10 standalone to operate the DAQ through its screen and keyboard
  • ORNVG-10-D

EV/HV NVH testing solution

New features

Release note NVGate V12 10 34.png



The objective of the EV/HV module is to characterize the electromagnetic forces which are responsible for the noise emission of an electric motor. This is achieved through 2 main steps:

  • eFrequencies determination and displays: They represent the characteristic frequencies that one may expect to find in the spectra. They are based on the specificities of the motor and depend of the RPM. For this reason, they are defined as harmonics.
  • Spatiograms analysis and displays. Spatiograms are calculated based on measurements of accelerometers data distributed around the surface of the motor stator.

Each spatiogram is representative of a spatial distribution of the electromagnetic forces. The sum of the contributions of each spatiogram leads to the global vibration response. Determining the spatiogram responsible of the vibration harmonic that should be decreased is one of the major objectives of the EV/HV module.

Getting started tutorial

The following tutorial is based on a provided project called "EVHV App Z12p2". To follow the steps below, one should preliminarily place this project in the NVGate projects directory. When starting NVGate the following window will display. One should open a project and select "EVHV App Z12p2". This chapter is meant to provide a first global approach, so to go through the main steps.

Selecting a measurement

From that point, the spatiograms for all wavenumbers (one spatiogram for each wavenumber) will be loaded and displayed.

Release note NVGate V12 10 46.png

Loading the spatiograms

Following that action, the spatiograms are automatically scaled and displayed as follows.

Release note NVGate V12 10 47.png

Spatiograms displays

  • The spatiograms are displayed here using the 3*3 configuration.
  • The left top window is a reference spectrogram, the others are spatiograms.
  • The spatiograms are automatically scaled using by default the "scale on max display option". It takes the Max of all results and sets it as the maximum value of the scale.
  • We now want to find the participating wavenumbers to certain harmonics which are of interest. As an example, we want to know what are the participating wavenumbers to H12 (Index 3). We see that the wavenumber 0 is clearly the highest contributor to H12.
  • Applying the eMarkers, the emarker with index 3 (H12) is shown on wavenumber 0. This confirms wavenumber 0 is the main contributor to H12.

Monitoring solution

New features


To respond to this application, the OROS Monitoring solution operates standalone and trigger actions based on defined alarm conditions looking at all channels. No need for the vibration specialist to stay on site waiting for noise and vibration levels to exceed unacceptable limits. Monitoring sends alerts autonomously and can be accessed remotely for further diagnostics.

Reboot Box with watchdogs available

Intended for long-term applications, the Monitoring application surveys the instrument, NVGate and PC operations continuity. In case of any failure, a watchdog restarts the complete measurement chain. In order to be 100% autonomous, the computer must be configured to restart after a power failure (using the proper "Restore on AC/Power Loss" feature in the BIOS).

The analyzer can be restarted as well using the "Autonomous kit" connected to the USB on the PC side and to RJ11 on the analyzer side as shown on the picture.

Using Monitoring
  • First, a dedicated project should be defined in NVGate. Setup a project dedicated to monitoring and display the scalar values to be tracked in the current layout.
  • Then, save the project and launch the Monitoring application. It will recognize the parameters displayed in the current layout.
  • Then, configure the condition you want to monitor for each scalar and define the corresponding action. To do that, select an operator to compare the measured value with the target value (which must also be defined). For example, if you select ">" and "2" for an acceleration scalar, when this value is larger than 2 the selected action will be triggered.
  • Finally, close the Monitoring application, close NVGate, shutdown your analyzer, and then launch the Monitoring Application. If everything starts by itself, Monitoring was setup properly and monitoring is initiated.

Release note NVGate V12 10 54.png

The Monitoring dialog window

The monitoring panel lets the user setup and visualize the indicators that are being monitored. Detailed setups are described in the list below:

  • Window: Selected scalar window’s name.
  • Module: Selected scalar module’s name.
  • Process: Selected scalar process’s name.
  • Channel: Selected scalar channel’s number.
  • Input Name: Selected scalar input’s name.
  • Values: Selected scalar values (SI).
  • Units: Selected scalar units.
  • Operator: Condition to be satisfied for actions:
  • ’>: If the measured value is greater than the target value, then action.
  • ’<: If the measured value is less than the target value, then action.
  • ’Cross: If the measured value crosses the target value, then action.
  • Target Values: Condition to be satisfied for actions.
  • Actions: What do you want to do when the condition is satisfied:
  • Activate / Deactivate outputs.
  • Run / Stop analyzer.
  • Trigger a User Event.
  • Launch a macro (coming from NVGate).
  • Hysteresis: Time hysteresis is the delay between each action coming from this scalar (e.g: 10s means the action cannot be triggered during the 10s following a triggered action.)
  • Led: Green if the condition is not satisfied (no action). Red if the condition is satisfied (action).

The proper setups should be selected in the parameters dialog:

Release note NVGate V12 10 04.png

"Keep NVGate/Analyzer awake": Ensure NVGate is running and the analyzer is on.

  • NVGate location: NVGate folder location (containing NVGate.exe).
  • Analyzer IP: If the IP is not defined correctly the application will not be able to check if the unit is on and therefore will also not be able to boot or shutdown the Analyzer.
  • Analyzer type: Analyzer type should be detected automatically. This is necessary to ensure the Monitoring Box functions properly.
  • Monitoring Box COM Port: Select the Monitoring Box COM Port. This is required to boot/shutdown the analyzer. If the Monitoring Box is not connected, or the correct drivers are not installed the list will be empty.
  • AutoRun Monitoring: Launch monitoring alongside NVGate.
  • AutoRun NVGate: Ensure NVGate is running at all times.
  • Start with (Project Name): Defines the project to be loaded in NVGate. If NVGate is restarted automatically, this project will automatically be loaded and monitored.

Improvements and new functions

DOF modification in measurement

Erroneous data on the FRF node and direction is a common issue while analyzing with FRFs for ODS or modal analyses. With NVGate 12.00, it is now possible to edit and correct the nodes and directions of an existing measurement.

Release note NVGate V12 10 55.png

For doing this:

  • Open Edit measurement from the ribbon.
Release note NVGate V12 10 56.png
  • Click on Select input.
  • Update the geometrical values: Component, Node and Direction, as well as input labels.
  • Click again on Edit Measurement to save the updated measurement.
Release note NVGate V12 10 57.png

Note: The Project Manager must be refreshed to see new DOF in it

Release note NVGate V12 10 58.png

User defined number of decimal digits for result figures

The resolution of the OROS instrument is high and may not fit the ones from some transducers (ex: temperature).

It is now possible to define the displayed number of decimal digits (precision) in the results windows by unit. This adjustment will be saved in the user’s preferences and applied permanently.

Set the adequate visible decimal digits for a physical quantity:

  • Open the Units & Quantity from the ribbon Home tab.
  • Select a physical quantity and create a new unit for it.
  • From the Unit dialog, set the number of decimal digits to be displayed.
  • Close the dialog with the Ok button.
Release note NVGate V12 10 59.png

The fixed decimal digit will apply when the new unit is selected. All displayed results will be adjusted:

  • Graphs scales
  • Cursors &, markers
  • Infotrace
  • Export
  • Scalar settings

Note: This fixed decimal setup disables the automatic figures display of NVGate. Fixed, Engineering and Scientific notation may lead to side effects, especially for small values. It is not compatible with Prefixed notation; in this case it will be ignored.

Data integrity (i.e. precision & accuracy) is not impacted, the results keep their intrinsic fidelity. It is possible to revert to former format at any time.

Extract DC tach from a dynamic input track

When the recorded signal does not feature parametric channels, the extraction of proportional DC tach is impeached. A new extraction procedure has been released in NVGate V12.00 using the Monitor in post-processing.

  • Open the ribbon Analyses / Monitor / Inputs button.
  • Select the DC tach Track in one Monitor channel.
  • From the ASB, add a DC tach and select the Mon of selected input as a source.
Release note NVGate V12 10 60.png
Release note NVGate V12 10 05.png

The DC tach is then available for any tachometer usage.

Memorization of calibrator type and settings

Release note NVGate V12 10 12.png

For both Acoustic and Vibration calibration, NVGate V12.00 memorizes the last used calibrator information.

Adjust the number of layouts in PC RAM

NVGate used to keep the last 5 layouts displayed in a NVGate session in RAM memory.

Reminder: Layouts are loaded in RAM after they have been shown through:

  • Shortcuts
  • "CTRL + SHIFT" to scan loaded Layouts from RAM
  • "CTRL + SHIFT + SPACE" scan & load Layout
  • Ribbon \ Measurement
Release note NVGate V12 10 61.png
  • Ribbon\ Display/Graphs
Release note NVGate V12 10 62.png
  • Workbook in the Project manager
Release note NVGate V12 10 63.png

The Layouts loaded in RAM can be switched rapidly. The unloaded ones require more time to be displayed. NVGate V12.00 allows users to adjust the maximum number of Layouts that can be loaded in RAM. This can be adjusted by editing the NVgate.ini file.

Simply add the line: LIVE_LAYOUTS=N

(x being the max. number of layouts loaded into PC RAM.)

Release note NVGate V12 10 64.png

Note: Display performance can be affected if you add more Layouts in RAM than your PC can manage. The Layouts content (Number of traces/lines & 3D/Colormaps) is a major parameter of display performances.

Kinematic Marker Database

A relevant bearing base is available within the NVGate V12.00 distribution. It includes bearing characteristics from main bearing manufacturers.

After NVGate installation, copy from the installer directory:

D:\ \Examples\Marker\Kinematic\ Roller bearing_DB example.csv

to the NVGate directory:

C:\OROS\NVGate Data\Markers\Kinematic\

This database includes bearing from SKF, NSK SNR…

Kinematic markers (FFT-Diag option) can be selected through the ribbon Display/Graphs/Marker.

Add/remove Window dialog

The former Add/Remove dialog (partially replaced by the "Results" one) used to generate boring and time-consuming reconstruction or scanning effects. These effects were triggered by 2 actions:

  • The Cancel button generates a long reconstruction of all layouts. It is more efficient to close and remove the last window manually
Release note NVGate V12 10 68.png

. The Cancel button has been removed to avoid this.

  • Clicking on the External results tab or opening the dialog without results to display led to scan the project manager, locking the software until the full scan. The External results tab has been removed to avoid long browsing of the project manager.

Note: Operating NVGate with a fully populated project manager may cause slower NVGate operations. It is recommended to reduce the number of projects and measurements in the project management using the following methods:

Release note NVGate V12 10 07.png

Archive: The Home\DataSet Share and Collate buttons allow selecting a set of Projects, Measurements and Models to be moved or copied to/from any location in your Windows environment. These features permit fast, easy and secured data archives and recoveries. All environement data are moved with the selected data (ex Mask, Macro, Signal, etc). See DataSet management in the NVGate user’s manual.

  • Filter: The project can also be filtered to show only a selection of Projects, Measurements and Models in your NVGate environment. This method does not move the data as the above one, it simply hides a part of it. Therefore, it is less efficient than the archive one.

Select the report template from NVDrive

Using the NVGate reports in automated operations reduce dramatically the system development time. In order to facilitate the integration of such applications, it has been made possible to control and select the report template (MSWord or Excel) through NVDrive or Python. The new NVDrive commands are:

  • ReportSelectInteractiveDocument
  • ReportGetInteractiveDocumentList

For details, see the updated NVDrive manuals for NVGate V12.00.

Fixed issues

The following issues found and reported by OROS customers in former releases have been fixed from NVGate V11.10.003 to NVGate V12.00.

Cascade mode (multi analyzers)

Cascade mode has been dramatically reviewed in depth to provide a robust error-free operation running NVGate with multiple instruments.

  • The clocks synchronization is now continuously monitored to avoid any de-sync to occur (cable issue) without warning.
  • Record files management has been secured by the rework of download and data assembly. It is now stable and faster.
  • Accesses to XPod and full tachometer settings have been made available in cascade mode offering the same usage in all modes.
  • System performances have also been improved in terms of launch and load time as well as results fluidity.

Cascade mode with NVGate V12.00 has benefits from a detailed test and validation campaign by the OROS team in our users’ applications. This ensures a comfortable usage of the OROS system in cascade mode.

Software stability has been carefully managed with a detailed tracking of any freezes, unexpected NVGate stops, incorrect behavior or side effects.

  • The memory management has been improved to reduce issues related to memory limits.
  • The compatibility with former files (setup, project, signal) have been adjusted to allow a full ascendant compatibility.
  • Settings dependencies have also been reviewed.

It results in reinforced stability with NVGate V12.00.

Recorder overwrite

The Overwrite function is a helpful capability of the Teamwork instrument. It saves data space by starting a recording before the expected phenomenon, to catch any unexpected event, and then overwrites the pre-test signals recording if its trigger is not met all without stopping the measurement.

This popular function used to generate side effects on recorded data integrity. The software has been reworked and secured to avoid and protect against such issues. A strong test and validation process has completed on this functionality.
