NVGate Mask And Alarm
Masks & Alarms
The Masks (also called Mask) are used to design a template for comparison with a measured result.
=
Manage===== Opens the Mask manager and displays the list of masks classified by project
- New: Creates a new mask in the project selected in the list. The "Masks settings" dialog box is displayed, in order to define masks characteristics.
Disabled if a template is already being edited.

Select an alarm and click the remove button
to remove the alarm.

- Select a bar
- Switches to "Select" mode. Bar is selected by clicking on it. The selected bar can be resized by dragging and dropping.
- Select all bars
- Selects all bars of mask. All bars can be resized by resizing one of them. The same offset is applied to all bars.
- Y scale: Switches between linear and dB scale on the Y-axis.
Edit grid
- Select point: A click on a grid line selects the corresponding point in the graph area.
- Edit point: You may double-click on a cell to edit the X-coordinate or Y-coordinate of a point.
The Y-coordinate value is bound by the Y minimum and maximum values.
The X-coordinate value is bound by the previous and next point’s X-coordinate.
Clicking on another cell or pressing enter key validates a value.
- Paste special: The edit grid or a part of the edit grid may be filled by editing the grid content in Excel®, and then copying and pasting from the clipboard.
Only selected cells are updated, if the grid content is valid.
The X-coordinates of the first and last point cannot be edited. The corresponding cells are disabled.
The values used in the Excel® sheet must be specified in the current units.
Profile mask settings
X axis
- Min: Minimum value on X-axis.
- Max: Maximum value on X-axis.
- Physical quantity: Physical quantity of the reference (represented on X axis).
Y axis
- Min: Minimum value on Y-axis.

Profile mask editor
- Add a point
- Switches to "Add point" mode. In this mode, a new point is created by clicking in one of the two graph areas. A point with the same X-coordinate is added to the curve of the other graphic area. The Y-coordinate of this point is calculated by linear interpolation between previous and next point.
- Select a point
- Switches to "Select" mode. A point is selected by clicking on it. The selected point can be moved by dragging and dropping. The drop area is bound by the X-coordinates of the next and previous points, and the Y-axis minimum and maximum values.
When a point is selected in one of the two curves, the point with same X-coordinate is selected in the other curve. When a point is moved, the point with the same X-coordinate in the other curve is moved also, in order to keep the same X-coordinate.
The two end points can be translated on the Y-axis only. Their X-coordinates are the X-axis minimum and maximum values, respectively.
- Select all points
- Selects all points on both curves. A curve can be translated on the Y-axis by moving one of its points.
- Remove selected point
- Removes the selected point from both curves. The previous point becomes the new selected point. Not available if all points or one of the end points are selected.
- Add point: Used to add a point by right-clicking on the desired position. A point with the same X-coordinate is added in the other curve. The Y-coordinate of this point is calculated by linear interpolation between previous and next point.
- Remove point: Used to remove the designated point by right-clicking on it. The point with same X-coordinate is removed from the other curve.
Only available when the user has right-clicked a given point (except end points).
- Move point: Used to move the designated point by right-clicking on it. A left click in the graph area determines the new position of the point. The point with the same X-coordinate in the other curve is moved also, in order to keep the same X-coordinate
- Y scale: Switches between linear and dB scale on the Y-axis.
Edit grid
- Select point: By clicking on a grid line, you may select the corresponding point in the graph area.
- Edit point: Double-click on a cell to edit the X-coordinate module or phase. A cell can be also edited by selecting it and pressing the enter key.
The module value is bound by the module minimum and maximum values. The phase belongs to the range [-Pi,Pi]. The X-coordinate value is bound by the X-coordinate of the previous and next points.
A value is validated by clicking on another cell or pressing the enter key.
- Paste special: The edit grid or a part of the edit grid may be filled by editing the grid content in Excel®, and then copying and pasting from the clipboard.
Only selected cells are updated, if the grid content is valid.
The X-coordinates of the first and last point cannot be edited. The corresponding cells are disabled.
The values used in the Excel® sheet must be specified in the current units.

The min-max mask is made up of two curves: from each point on the mask edited, two points with same X-coordinate are generated, applying the offset ratio negatively and positively on theY-coordinate.
A click on the OK button changes the mask edited to a min-max mask, which is displayed in the editor (see Min-Max mask editor).

Link
This part of the Tools tab provides a link to external software. One a target is selected, each mousse click on the Execute button launches the target software. As a reminder, the target software can be any executable file from windows (.bat, .exe, shortcuts, etc...). Simply add one target in the c:/OROS/NVGated Data/Links directory and you will be able to use directly for the NVGate interface
