Dataset management

Data management is fully integrated into NVGate. This essential feature of your analyzer provides search & select functions based on the meta-data content of the project manager items.

Benefits

The objective of OROS Dataset management is to provide self-described data and avoid the constraints of databases organization. The data can be exchanged in any directory in the PC environment (LAN, Disk, USB, etc...).

With OROS Dataset management it is simple to:

• Share a project, a model or a measurement called File 1, without any explanation,
• Access projects, models and measurements from any network or local directory,
• Work together with your colleagues on a common project,
• Filter your data environment (project manager, open dialogs) simplifying the data access,
• Archive and retrieve your complete dataset without reminding the files names.
• …

Data organization

The dataset management proposes a general-purpose data organization based on 3 levels of data:

• The context, which holds the campaign or site or customer information. Located in the projects, it does not hold additional data than properties. The context is usually defined by the manager (test, service and engineering).
• The setup, which holds the acquisition and analyses description type. Located in the models, it contains the complete analyzer setup plus properties. The setup is usually defined by the experts (from your company, a services company, your local support or OROS customer care)
• The measurement, which holds the measured/analyzed data and specific measurement details. Located in the measurement, it contains data, setup (workbook) and properties. The measurements are usually generated by the operators (the one who make the measurements)

Self-description

Each item holds properties that describe what is not available from the workbook, data and additional files. Properties are fulfilled by users or automatically according to the current context.

The data are located in the NVGate data directories where any type of additional files (pictures, audio, schemes, instructions, etc…) can be associated to detail their description.

Heritage

The Data organization is used to propagate the properties to the final result; the measurement. The measurement inherits properties from the opened project and the last loaded Model. This allows getting the context and setup correctly described in the measurement.

The heritage benefit is double; first it reduces the information to be fulfilled and secondly it allows sharing the measurement without project or model.

Properties inheritance

Filtering

The properties are helpful arranging the projects and measurements in coherent sets. NVGate proposes Excel like filtering features to hide unused Item in the project manager.

Data mining

The self-description brought by the properties allows easily mining Projects, Models and Measurements in local or shared data storage. Based on properties filters and in-depth scanning, the OROS dataset management features efficient data browsing.

Data sharing

Share/Collate functions bring simple ways to exchange Projects, Measurements and Models with your colleagues, customers and managers. Copy/Paste conflicts are silently managed; Projects merge automatically the Measurements and Measurements carry the source Model. Additional non-OROS files are also transported with the NVGate ones.

Data security is guaranteed with copy/move/delete log files and windows like conflicts management.

Data archiving

The Share/Collate allows efficiently archiving and retrieving data on your PC, on an external drive or through the network.

Properties

The properties are used as meta-data to enrich projects, models and measurements. They are informed while saving the items or by editing the properties from the project manager.

The properties belong to 3 different categories:

• The OROS properties are automatically informed such as Dates, Author, Project and Saved results type
• The OROS user properties are predefined to be informed by the user: Comments, Site, Installation, Intervention, Measurement type, UUT, Serial number
• The Users properties are created and filled by the operator while saving or by editing the properties. Ex: Customer name, Transducer type

Suggested properties usages

While saving data (Project, Model or Measurement) the save dialog box proposes the following layout (same for Project, Model and Measurement):

---

On the left side the Item’s name and the comments. Current Project and Model comments will inherit to the Measurements.

On the right side the OROS user and User properties. Current Project and Mode properties will inherit to the Measurements.

Starting NVGate

Click on the NVGate Icon from your desktop. The connection dialog appears. Select operation mode (Connected, Office or multi-instruments) See page 20 for details

Click on start.

====Open/create a project====

When you launch NVGate, the Start dialog is proposed:

This dialog is also available from the ribbon Home/Start/Start

Selecting Open Project opens the Open Project dialog which behaves as the single Item selection.

File:Usersmanual 01.png

Select your project and click Open button.

Selecting New project opens the following dialog:

Fulfill the necessary properties and comment to describe the context of this project and click on Ok button.

Select a setup

In both above open project cases, the project is opened, no setup is loaded. The Setup is loaded further this first action. There are few ways to load a setup prior being ready for acquisition and analyses.

Check the Load setup box in the open project dialog in order to select the setup while exiting the Open project one.

Use the Home/Setup/Load ribbon button.

The load setup dialog behaves as a single Item selection. It allows loading setups from Models Measurements and Projects or creating setups for on-line or post-analysis:

Pre-defined setups

OROS provides various predefined models that contains basic and advanced setup examples of analysis. These setups are available from the Load Model dialog.

This setup contains customized items:

• Front-end setup
• Analysis setup
• Layouts
• Save setup
• Control panel

Select the Tree view in the Load setup dialog to see the directories using the Flat/tree button

Tree view

Quick directory contains setups of the instrument for either post-processing or on-line analysis.

The mapped directory is the quick directory in the workbook library which is defined in the NVGate Environment paths. Default is: C:\OROS\NVGate data\Workbook Library\Quick\. It is possible to add additional models in this directory according to your organization chart.

Quick Models name defines the characteristics of the corresponding analyses:

AAA_M_W_N

• AAA is the analysis mode (FFT, REC, ORD, etc..)
• M is the mode: O=On-line, P=Post-analysis
• W is present for waterfall results (profile, 3D)
• N is the number of channels

Advanced Models

This directory shows applications-oriented examples.

The mapped directory is the advanced directory in the workbook library which is defined in the NVGate Environment paths. Default is: C:\OROS\NVGate data\Workbook Library\advanced\.

User’s models

This directory holds the Models saved by the users of the NVGate installed in the current PC.

Direct setup

From a preset model, an existing setup or from scratch the measurement setup (Front-end, analysis, display and save) is available from the GotoResults windows. This set of dialogs come as an additional layer on NVGate interface. The background interface remains accessible (Clickable) while these dialogs are visible

Setup buttons

Access to the GoToResults windows is continuously available from the NVGate bottom bar.

The 2 first buttons control the visibility of the corresponding windows Inputs selection and Show results. Click once to show the window, click again to hide it. The 3^rd button only opens the Results overview.

File:Usersmanual 109.png

These 3 buttons show the windows described below.

Inputs selection

Call

Available from both the bottom bar and Home\Start\Select Inputs this window allows selecting the inputs to be used and setups their acquisition.

Hide the window by clicking on its control button, closing the window (up-right red cross), clicking on the Results button to show the next window.

Usage

The Inputs selection window allows access to the other items of the NVGate interface (ex: check ICP, Autorange, change sampling frequencies, graphs…) while it remains open.

File:Usersmanual 110.png

The actions in this window apply immediately to the analysis, there is no possible cancel. In the same way actions in other parts of NVGate are immediately reflected in this window.

This window manages dynamic inputs only. For using parametric, CAN or ext. synch inputs, one should use the acquisition tab of the ribbon.

Operations

The Inputs selection window allows activating and setting-up the dynamic inputs in a fast and smart way. Inputs are activated and set to a physical quantity when the corresponding check box is clicked.

Selection

This table allows selecting one or multiple cells in an Excel like mode, using mouse drag',' keyboard arrows and SHIFT/CTRL keys. After edition, the focus is automatically set to the next cell for continuous operation with the keyboard:

Exit key	Return	Tab	Left arrow	Right arrow	Up arrow	Down arrow
Next cell	Down	Right	Left	Right	Up	Down

Edition

Editing a cell or a group of cells is direct, no need to double click, simply enter the values or initials for combo boxes. Hit the <Space> key to open the combo with the current selection. This allows using the keyboard only while setting cells in a column or a line.

Add physical quantities

The 3 basic physical quantities (Voltage, Acceleration and Acoustic pressure) used in noise and vibration are proposed as default. Changing one input physical quantity will add a new column with this physical quantity.

In addition to the basics and active physical quantity, the columns also show the physical quantities of deactivated inputs. This is useful to add default physical quantities to your models.

Transducers

The list of possible transducers is adjusted to the input physical quantity. Ex: if an input is set to acoustic pressure, only a microphones’ list is proposed.

Sampling & groups

The sampling setting is new. It defines the recording sampling and the analysis bandwidth for each group of inputs. The groups correspond to the inputs physical quantities. See the Autobandwidth chapter for more details

There are 2 samplings, High and Low. Each sampling can be adjusted from the table with Right click -> Change -> Select new sampling.

Changing the sampling of one input will apply to all input in the same group. For applying different samplings to inputs with same physical quantity, use the ASB.

Sampling settings are also available from the ribbon Measurement\Front-end\High Samp. and Low Samp. and from the Front-end Module in the Analysis Setting Browser.

Record signals

Check this box to ensure the recording of all active inputs. This includes the DC inputs (parametric), the Ext Sync. and the CAN ones.

Unchecking this box just set the recorder to off. The inputs remain set in the recorder. This is helpful to temporarily pause the inputs recording; especially on setup fine tuning.

File:Usersmanual 05.png

The Record signal is also available from the ribbon Measurement\Front-end\Records signal. And from the show results window.

All instances of this setting work in the same way. Wiith this method, the recorder signals are not automatically displayed.

A new button is available to monitor temporarily or continuously the signal: Measurement\Control\View recording. It opens the signal monitoring window on top of the current layout. In the case of this window is already open in another layout, it swaps to this layout.

Access to all

By default, the window shows only the basic settings. In order to get the full columns, flyover the right side of the table and click on the grayed arrow.

Same with the left arrow to return to the basic view.

Post-analysis

Inputs selection window works on both on-line and post-analysis modes.

Show results

Call

Available from both the bottom bar or directly following the Inputs Selection window, this window allows displaying and saving results from activated inputs.

Hide the window by clicking on its control button closing the window (up-right red cross) or by clicking on its corresponding button in the NVGate bottom bar.

File:Usersmanual 112.png

Usage

The Show results window allows access to the other items of the NVGate interface (Add/Change layout, Setup tachometer…) while it remains open.

File:Usersmanual 30.png

The actions in this window apply immediately to the analysis, there is no cancel possible from this window. In the same way, actions in other parts of NVGate are immediately reflected in this window.

This window manages to connect and display result from FFTx, SOAx, OCT plug-ins only. For results from TDA and OVA, one should use the Acqusition\Inputs\Connect inputs button followed by the Display/Graphs\Windows\Add/Remove one from the ribbon.

Show results

The Show results window allows displaying and saving results without connecting inputs or tracks to the plug-in analyzers in advance.

---

Results to be displayed are selected as follows:

1.

Select the plug-in which calculates the results,

2. select the results’ familly between:

• Main is for results imediatelly provided by the analysis like the trigger blocks, RPM, spectra, FRFs, …
• Profile is for scalar profiles like order tracking, acoustic level, RPM profiles, …
• Waterfall is for 3D results.

3. Select the result type,

4. select the Inputs/Tracks to be displayed. This list gathers the sources in groups according to their physical quantities. One can develop the group for partial selection.

Go. Use the Show button to display your selection. This button operates in 2 ways:

• Add a new window in the current layout with the selected results by clicking the button
• Drag & Drop the button to an existing window of the current layout to add the selected results in this window.

References

Cross functions (FRFs, ORFs, Coherence, etc..) are selected through the bottom right area. The references are displayed as the inputs/tracks using the physical quantity group. There is no need to predefine the cross function from the Plug-in settings.

Orders and overall

For order tracking, the Show results window features a fast and simple order selection mode. While selecting order-based result, one can enter the chosen orders in the bottom right area of the window.

Values are entered directly using the keyboard; The Enter and up/down keys will navigate to next or previous lines in the list.

If the plug-in channels show different orders to track for one line, "Mixed" will be displayed.

Save results

Results to be saved (i.e. added to the save selection list) are selected as for showing it.

There are 3 ways to save the results:

• Manually by using the save button. This will add the selected results to the save selection.

Automatically and continuously, by checking the Save displayed results check box at the bottom of the window. This will continuously add the displayed results to the save selection. Results remain in the save selection list, even if they are removed from the layout.

Automatically once by using Measurement\Save\Add All Results button from the ribbon. This button acts like the save all display result but only at once.

• This button is grayed when all displayed results are already in the save selection
• When the Save displayed results is active, this button shows

Parameters

The bottom half of the window allows adjusting the selected plug-in parameters and triggering.

File:Usersmanual 114.png

1. This button opens the active plug-in properties. NB: it is also possible to access it from the ribbon while the window is open. Helpful with the directly available main settings.

2. Click here to open the Events connection window, where one can associate event with plug-ins’ Start, stop or trigger.

3. Activate the plug-in tach with this combo box. The tachometer properties will be proposed just after selecting the tach. The corresponding input (dynamic, or ext. synch) is automatically activated.
NB: The selected tachometer is associated with the plug-in. For profile and waterfall results, the corresponding tachometer is showed as: XXX tach (ex. FFT1 tach, or SOA2 tach)

4. Click on the engine tachometer icon to setup the delta RPM for scheduled analyses with Profiles and Waterfalls.

Results overview

Call

Available from the bottom bar. This window shows a synthetic table of the displayed and saved results. Close the window by clicking on its control button closing the window (up-right red cross).

Usage

The table summarizes all the displayed and saved result (i.e. present in the Save Selection list), by:

• Plug-ins
• Type of results
• Groups (i.e. Physical quantity)

The 2 columns at the right, indicate what is done with each set of results. Show for the displayed results and Save for the to-be-saved results.

The check boxes have 3 possible status:

Checked, means all the inputs with these type and physical quantity, calculated by the plug-in are saved and/or displayed.

Unchecked, means none of the inputs with these type and physical quantity, calculated by the plug-in are saved and/or displayed.

Partial, means only a part of the inputs with these type and physical quantity, calculated by the plug-in are saved and/or displayed. One can check and uncheck the Save column boxes. Partial status boxes change to checked or unchecked only.

It is possible to check the results one by one with the Save Selection window by clicking on the corresponding button at the bottom-right of the window

Interface description

Vision

The Vision interface gathers the analyzers functionalities in simple, clear and easy to identify tabs organized according to the main operations (First steps, measuring, results edition, configuration build-up, automation, general setup etc…).

Key features have been emphasized by the Vision interface, guiding the users to the best way using their OROS 3-Series analyzer.

Tab & groups

The new interface layer features 7 standard tabs (optional tab are also visibles). Each tab contains a set of groups which gathers settings, info and buttons about one topic (e.g. disk, FFT or transducers).

File:Usersmanual 121.png

Actions

The groups contain buttons, setting and check boxes of different types:

Buttons: Left click on it leads to an action or opens a dialog box.

Examples:

for auto scale or

for inputs connection

Status buttons: These buttons work like the standard ones but they can be activated or de-activated. They are used for changing a state. An activated button is slightly darkened.

Examples:

that switches between on-line and post-analysis modes,
or

for enabling the marker manipulations.

Settings: Provide a direct access to one of the ASB setting. Allow to continuously check the setup.

Examples:

for a numerical setting,

for a Boolean (check box),

for a selection in a list

Multi-actions: These buttons work as the standard ones but it is possible to select their action from a list. When an action item is selected from the list, it becomes the default action of the button, the icon is changed.

Examples are: Marker, or User selection.

Status buttons: These buttons change and show the status of the active element (windows, trace, etc..). Selecting one of the items in their list will apply this status to the active element. The status buttons change depending on the applied changes to the element (or change of element). It is useful to monitor and see immediately in what state is a 3D or the active user for example.

Note: The buttons are highlighted when the mouse pointer pass over an active button.

FIle Menu

A unique "File" menu is available on upper left for input/output file operation. It allows loading/saving setups and provides access to the on-line help.

Status bar

At the bottom of the screen a fixed status bar maintains a continuous monitoring of the inputs and analysis:

On line help on Vision ribbons

The content of the Vision™ ribbons are connected to the on-line help.

In order to get help from one of the Vision elements, activate the help mode by clicking on the upper right question mark. The cursor switches to a pointer + question mark. Then click on the desired item. The corresponding page of the reference manual will be opened.

Note that the latest pdf reader software is supported with NVGate: Acrobat reader 32 or 64 bits and Acrobat and any other pdf reader. The ability to open the manual at the corresponding pages is supported by Adobe™ products only. OROS recommend using acrobat reader using the on-line help functionality.

Minimize ribbon and full screen

In order to gain space on the NVGate screen during acquisition and analysis the NVGate ribbon can be minimized. It operates like in the MS Office suite:

Use the upper right arrow to minimize or reset the ribbon size. When the ribbon is minimized the tab header remains visible. Their content is accessible by clicking on the corresponding tab header. The full screen function has been improved. It hides the application top bar as well as the windows bottom bar.

Log window

In the Home tab, tick/untick the Log window

to show/hide the Log window (Analyzer settings, Warning and Macro Trace information).

Analyzer Settings

The Log Window shows all the changes made to the modules (Front-end, Filter builder, Monitor, FFT x, etc.) in the ASB.

Some setting values need to be adjusted when another setting value is modified. So when you change a setting value in the ASB (new value: ...) which may affect another setting value, the Log window marks the changes made by the analyzer (adjusted to: ...).

1. Right click on this area:

2. Select Copy (to paste a setup in a text document for example)

3. Clear the display in the Analyzer Settings tab.

Warning

The Warning tab shows any unauthorized operations you have carried out or errors reported by NVGate®.

1. Right click on this area:

2. Select Copy (to paste a setup in a text document for example)

3. Clear the display in the Warning tab.

Macro Trace

The Macro Trace tab shows the operations (the start and stop macro execution, errors) made in the macro mode.

Warnings do not stop macro execution but major errors will.

1. Right click on this area:

2. Clear the display in the Macro Trace tab.

Tip: double clicking on the error icon in the Macro Trace tab will open the Macro Editor on the failed command.

Workspace

File:Usersmanual 39.png

The workspace is a dockable tab on the left part of the NVGAte interface it holds 3 main themes of the analyzer interface.

Analyzer Setting Browser (ASB)

The analyzer is controlled through a tree of settings called the Analyzer Setting Browser (ASB). This tree consists of a set of modules that allows to setup the signal acquisition, play back and processes.

Note: The "information" icon

File:Usersmanual 134.png

may be found next to a setting. It means you cannot change the setting value.

Tip: When using the right click on any item from the ASB, you can copy the value(s) contained in the selection (it can be a module, collection, sub-module or just a setting) and paste it (them) into another item which contains compatible value(s). It is also possible to drag and drop a scalar type setting

File:Usersmanual 135.png

from the ASB to a displayed window (for example the center frequency of the FFT Zoom).

Ways of editing a setting

Right click on an item and select Properties. You can check your setup and also change the settings in real time by double-clicking on the cell you want to change. The drop-down menu or the mouse wheel can also be used.

A setting can be set to its default value by right-clicking on it and by selecting Set to default.

File:Usersmanual 136.jpg

Analyzer states

In the analyzer Setting Browser, you can find the analyzer states icons. They were made to show you visually the state of each plug-in analyzer at the same time. Follow the icon descriptions:

File:Usersmanual 137.png

The plug-in analyzer is stopped

File:Usersmanual 138.png

The plug-in analyzer is running

File:Usersmanual 139.png

The plug-in analyzer is paused

File:Usersmanual 140.png

The plug-in analyzer is recording

File:Usersmanual 141.png

The plug-in analyzer is waiting for a trigger: defined Event or Manual (

File:Usersmanual 142.png

)

File:Usersmanual 143.png

The plug-in analyzer is waiting for the user answer: Accept (

File:Usersmanual 144.png

) or Reject (

File:Usersmanual 145.png

) the signal

File:Usersmanual 146.png

The plug-in analyzer is failed (the analyzer is not able to do the data acquisition anymore; a warning message will appear)

Modules

There are 4 types of modules:

File:Usersmanual 147.png

The sources that acquire store and play back signals

File:Usersmanual 148.png

The resources that provide events, filters, weighting windows, and tachometers to the plug-in analyzers

File:Usersmanual 149.png

The plug-in analyzers that process independent analysis modes

File:Usersmanual 150.png

The Waterfall that synchronizes the results computed by the plug-ins

The modules contain different functions located on sub-modules.

A collection

File:Usersmanual 151.png

is a box that contains a group of sub-modules of the same type (inputs, filters, channels, etc.). The sub-modules of collection can be active (visible) or inactive (hidden). Right click on it to add/remove channels.

The settings are inside the sub-modules. The ASB has a maximum depth of 3 levels: module, sub-module and setting. In the case of multiple similar sub-modules (inputs for example), the user sets his analyzer simply by changing the settings. The settings are grouped in families:

• The scalar settings

File:Usersmanual 152.png

are every numerical value which can be entered from the keyboard.

• The label settings

File:Usersmanual 153.png

are every character string which can be entered from the keyboard.

• The enumerated settings

File:Usersmanual 154.png

are a selection of an item from a list (items are character strings or numbers).

• The Table setting is a group of values
• The Matrix setting is selection of a matrix’s intersections
• The Boolean setting

File:Usersmanual 155.png

allows activating or deactivating functions (inputs, auto-calibration, zoom…)

Project Manager

The Project Manager is used to store all your projects, results and measurements…. There are several display options that enable you to show or hide certain items.

Tip: you can drag and drop any type of result from the Project Manager to the windows top to display the result window.

The Project Manager is made up of 3 main parts: the Workbook, the Project and the Measurement.

Workbook
