NVGate Ribbons: Display
The "Display/Graphs" tab
This tab covers the results display control. It allows creating, fulfilling, arranging and viewing the windows and layouts. It controls the scale, units, weighting and data operations of any graphs, manages the waterfalls and extraction graphs and the markers.
Windows group
This part of the display/graph tab manages the windows creation, their refreshment and the infotrace view/hide.
See Chapter 7 - § Graph for details
Note: Clicking on the bottom right icon (
) opens active window properties dialog. The content of this dialog varies depending on the windows type.

Marker group
Features a complete set of real-time markers that help identifying typical signature and points of exception in both time and spectral graphs.
The marker group allows selecting and positioning the chosen marker.
.
The first button corresponds to the marker to be added. It is a multi-action button that gathers all marker type in its list.
Free marker: Switch the cursor to deposit a free marker in the click location. The free marker can be positioned everywhere to add a legend in a spectra, profile, 1/n octave and waterfall section. See chapter 2 –Display - § Marker/free marker for details
Harmonic marker: Switch the cursor to deposit a set of harmonic in the click location. The harmonic marker can be positioned everywhere in a spectra and waterfall X/Y sections. See chapter 2 –Display - § Marker/harmonic marker for details
Peaks marker: Switch the cursor to add a set of peak detection markers in the clicked graph. The peak marker detects automatically the peaks in the spectra and waterfall X/Y sections. See chapter 2 –Display - § Marker/peaks marker for details
Max marker: Switch the cursor to add a set of maximum detection markers in the clicked graph. The max marker detects automatically the maximum in the spectra and waterfall X/Y sections. See chapter 2 –Display - § Marker/Max marker for details
Side band marker: Switch the cursor to add a side band marker at the clicked location. The Sideband marker can be positioned everywhere in a spectra and waterfall X/Y sections. See chapter 2 –Display - § Marker/Sideband marker for details
Power band marker: Switch the cursor to add a power band marker at the clicked location. The power-band marker can be positioned everywhere in a spectra and waterfall X/Y sections. It extracts the RMS power in the selected band taking in account the equivalent bandwidth of the weighting window. See chapter 2 –Display - § Marker/Power band marker for details
1/n Octave data marker: Switch the cursor to add a 1/n octave data marker at the clicked graphs. The 1/n octave data marker can be positioned in CPB spectra and waterfall X/Y sections of the same type. It extracts the list of the band levels in db or linear units into the infotrace. See chapter 2 –Display - § Marker/Octave marker for details
Kinematic marker: Switch the cursor to deposit a set of harmonic in the click location. The harmonic marker can be positioned everywhere in a spectra and waterfall X/Y sections. See chapter 2 –Display - § Marker/Octave marker for details
Period marker: Switch the cursor to add a periodic marks at the clicked location. The period marker can be positioned trigger blocks. Operates like an harmonic marker but in the time domain. See chapter 2 –Display - § Marker/Kinematic marker for details
Record marker (CTRL+M) Using this shortcut while the analyzer is recording, add record marker to the signal. If there is a recording window, the maker is displayed. During the recording, a comment can be added to the record marker, via the properties dialog box.
The record marker is available from the Measurement\Control group. See Measurement tab§ in this document.
The rest of the group is dedicated to the marker adjustments:
Marker mode: Switch between the marker mode (the cursor controls the marker) and the last used cursor mode. See this chapter (6) - §Tabs/ Measurement tab/graph group for details
Move marker: Moves the selected marker of the active window by one step of spectra resolution to the left or right
Move marker by 1/32nd of step: Moves the selected marker of the active window by a 1/32nd of spectra resolution to the left or right. Allowed only if the marker is located in the vicinity (+/- 1 step) of a peak and the X& Y interpolation are enabled
3D group
This group provides general purpose tools about the Waterfall 3D graphs.
The first button corresponds to displayed graphs. Each Waterfall windows may displays up to 4 different graphs. It is a multi-action button.
3D only: Shows the 3D graph only. This graph can be a 3D plot or a color map.
X/Y only: Shows the X/Y extraction graph only. This graph contains the spectra at the cursor position and the X/Y sections.
Y/Z only: Shows the Y/Z extraction graph only. This graph contains the time (or ref) profile at the cursor position and the Y/Z sections.
Extraction only: Shows the Order/frequency extraction graph only. This graph contains the order/frequency profile at the cursor position and the extraction sections.
All graphs: Shows all the graphs in a matrix.
See chapter 2 –Display - § Contextual menu/Window menu/Waterfall menu for details
The second button controls which way the 3D data are plotted. It is a multi-action button.
3D Isometric: Plot the spectra (or trigger blocks) along a Z axis with the same scale whatever is the position. The Z axis angle is modified by the rotate button.
3D perspective: Plot the spectra (or trigger blocks) in a true 3D space, taking in account the perspective. The global orientation of the gathered spectra can be changed using the rotate button. This type of view allows looking at the waterfall from any side
Time/frequency color map: Plot the spectra (or trigger blocks) on 2D map with the color representing the point amplitude. This plot show the Time (Y) Vs frequency (X) arrangement
Frequency/time color map: Plot the spectra (or trigger blocks) on 2D map with the color representing the point amplitude. This plot show the Frequency (Y) Vs Time (X) arrangement
The last 3 items control the 3D graph rotation and manage the sections:
Rotate: Toggle the rotating mode. Allows rotating the 3D graphs with the mouse when enabled. Disabling this item return the mouse to the previous mode.
Add section: Add a copy of the cursor location in each of the 3 extraction graph
Section manager: Open the waterfall section manager.
