[[NVGate dataset management|See NVGate Dataset management page]]
===Starting NVGate===
====Tutorial====
This example will show you how to use the "GoToResult" of NVGate to quickly perform a complete measurement setup from the start of the software. We will use an OR36TW analyser and NVGate V12.10. We will also use a demonstration rotorkit made from a standard model building electric motor and a gearbox. We will analyse the vibrations of this kit with two 100mV/g accelerometer, connected to the inputs 1 and 2 of the frontend, and use a 2 pulse/revolution tachometer, connected to the Ext. Sync.1 input, to extract orders.<br><br>
Here we will see how to simply use NVGate to record the raw data, displaying the FFT, and display the tracking of the two first orders of all the sensors used.

=====Edit the Sampling Rate=====
=====Edit the Sampling Rate=====
The sampling rate is the rate to which the signals will be sampled by the analyzer. This will define the maximum frequency that can be analyzed during the online analysis or in post-analysis on the recorded signals. However, a higher sampling rate will need more computational power. You may choose a sampling rate that is twice the highest frequency you want to analyze.

====GoToResult====
=====Display=====
 
 
Available from both the bottom bar and ''Home\Start\Select Inputs'' this window allows selecting the inputs to be used and setups their acquisition.
 
 
'''Access to the ''' ''GoToResult'' '''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<sup>rd</sup> button only opens the ''Results overview''.
 
These 3 buttons show the windows described below.
 
[[Image:V11_release_08.png|framed|none]]
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.
 
===== Step 1: Inputs selection=====
[[Image:Usersmanual_26.png|framed|none]]
 
======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.
 
[[Image:Usersmanual_110.png|framed|none]]
 
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 editing, the focus is automatically set to the next cell for continuous operation with the keyboard:
 
{|border="2" cellspacing="0" cellpadding="4" width="100%"
|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 <nowiki><</nowiki>Space<nowiki>></nowiki> 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<nowiki>’</nowiki> 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 -<nowiki>></nowiki> Change -<nowiki>></nowiki> 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&nbsp;pause the inputs recording'''; especially on setup fine tuning.
 
 
[[Image:Usersmanual_05.png|framed|none]]
 
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'''.
 
[[Image:Usersmanual_111.png|framed|none]]
 
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.
 
=====Step 2 Show results=====
[[Image:Usersmanual_28.png|framed|none]]
======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.


[[Image:Usersmanual_112.png|framed|none]]
The acquisition is now complete and the results are displayed .  


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


[[Image:Usersmanual_30.png|framed|none]]
[[Image:Usersmanual_165.jpg|700px|none]]
 
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,
[[Image:Usersmanual_38.png|framed|none]]
 
 
 
2. select the results<nowiki>’</nowiki> 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:
 
* <u>Add a new window</u> 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 <u>add the selected results in this window</u>.
 
======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======
 
[[Image:Usersmanual_04.png|framed|none]]
 
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.
*
[[Image:Usersmanual_113.png|framed|none]]
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.
*
[[Image:Usersmanual_27.png|framed|none]]
 
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.
 
[[Image:Usersmanual_114.png|framed|none]]
 
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<nowiki>’</nowiki> 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. <br>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''.
 
=====Step 3 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.
 
[[Image:Usersmanual_115.png|framed|none]]
 
The check boxes have 3 possible status:
 
*
[[Image:Usersmanual_116.png]]
Checked, means all the inputs with these type and physical quantity, calculated by the plug-in are saved and/or displayed.
*
[[Image:Usersmanual_117.png]]
Unchecked, means none of the inputs with these type and physical quantity, calculated by the plug-in are saved and/or displayed.
*
[[Image:Usersmanual_118.png]]
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===
 
[[NVGate_Ribbons_overview |See interface overview page]]
 
======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=====
[[Image:Usersmanual_39.png|framed|none]]
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 [[Image: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 [[Image: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'''.
 
[[Image:Usersmanual_136.jpg|framed|none]]
 
======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:

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:
 
[[Image:Usersmanual_147.png]]
The sources that acquire store and play back signals
 
[[Image:Usersmanual_148.png]]
The resources that provide events, filters, weighting windows, and tachometers to the plug-in analyzers
 
[[Image:Usersmanual_149.png]]
The plug-in analyzers that process independent analysis modes
 
[[Image: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'''
[[Image: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
[[Image:Usersmanual_152.png]]
are every numerical value which can be entered from the keyboard.
* The label settings
[[Image:Usersmanual_153.png]]
are every character string which can be entered from the keyboard.
* The enumerated settings
[[Image: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<nowiki>’</nowiki>s intersections
* The Boolean setting
[[Image: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'''.

Load the configuration

This will open the Load setup window. This window allows you to load the configuration from a pre-saved model, a previous measurement, create a new setup or opening a signal for post-analysis. Here we want to setup a new configuration, we will select New On-Line :

SelectNesConfig.png
Select the inputs

Once you click Load, the input setup window appears :

InputEmpty.png


This window can be called anytime from the GoToResult. See Input selection for the detail of the parameters.

As we use 2 accelerometers, select check the "Acceleration" boxes for inputs 1 and 2, and select the appropriate sensors in the "Transducer" column for each inputs. If you don't see your specific sensors, please fill your transducer database.

AddInput.png


To add the inputs into the recorder, check the Record signals box :

CheckRecorder.png


By doing this, any inputs (even if added later) will automatically be connected to the recorder plug-in.

Edit the Sampling Rate

The sampling rate is the rate to which the signals will be sampled by the analyzer. This will define the maximum frequency that can be analyzed during the online analysis or in post-analysis on the recorded signals. However, a higher sampling rate will need more computational power. You may choose a sampling rate that is twice the highest frequency you want to analyze.

To edit the sample rate, do a right click on the sampling case. 

Change sampling.png

Here we have a 25,6kS/sec that allow us to analyze the data up to 10kHz.

Setup the analysis

Once the inputs are correctly declared, click on Results to setup the analysis :

ClickOnResults.png


This will open the Results window :

Gotoresults2022.png

This window can be called anytime from the GoToResult icons. See the Show result section for detail about this window.

Displaying the FFT analysis

We will now display the average spectrum for the two inputs :

AddingFFT.png

Once you selected the result you want to display, click on DisplayButton.png to display the graph in the current layout.
Make sure you checked the box Save displayed results to save the result at the end of the measurement.

The FFT graph window now appear in the current layout :

.

Setting up the FFT analysis

We can now setup the FFT to optimise the analysis. To access to the setup parameters, click on settings in the Show result window : SettingFFT.png

Here, the maximum speed of the motor is 2000RPM. That make the first order at 2000/60 = 33Hz and the tenth order at 330Hz. In order to optimize the computation, we will then limit the FFT bandwidth to 5kHz, the overlap to 67% and the number of lines to 1601 to have a correct precision. ModSettingFFT.png

You can then press OK to close this window. For details about the parameters, please visit the NVGate FFT page.

Adding Order Profile

We can now setup and display the order profile. To do this, select the Sync. order 1 tab of the Result window.

SOAShowResult.png


Here, we want to display the first two orders profile for each input. To do so, select the profile tab, and select Order & Overall under Result and Acceleration (that will select the 2 acceleration channels) under input. To track the 2 first orders, you can simply enter 1 and 2 under the Tracked Order section.

Finally click on DisplayButton.pngto display:

AddOrderProfile.png


The profile graph is now displayed on the current layout along with the FFT spectrum graph :
