To quit the zoom mode, press the zoom button again: this will activate the cursor mode.
	Zoom in Y: Makes the Y-scale two times smaller.
	Zoom out Y: Makes the Y-scale two times larger.
	Zoom in X: Makes the X-scale two times smaller and sets the minimum and maximum values so that the cursor is in the middle of the graph.
	Zoom out X: Makes the X-scale twice as large and sets the minimum and maximum values so that the cursor is in the middle of the graph.
	Autoscale (CTRL+A) : Adjusts the Y scale of all the windows in the current layout. The scales are adjusted to the largest trace amplitude (min and max) in each graph. A 10% margin is added to these values to facilitate visibility. Note: The minimum Y scale width cannot be lower than the active signal precision.
	X/Z Adjust (CTRL+Q): Adjust minimum and maximum values of the X or Z-scale so that every point on the axis is visible. See chapter 2 –Display - § Display window/graph menu / X zoom for details
	Scale (CTRL+F5): This mode is used to modify scales using the mouse in graphs, by moving the cursor on the scale. The shape of the mouse pointer changes depending on the position of the mouse pointer on the scale: Use the mouse wheel or the Up/Down arrows to change the scale value. If the Ctrl key is pressed, the changes are five times smaller, for more precise adjustment of the value modified. To quit the scale mode, press the scale button again: this will activate the cursor mode. Mouse cursor Position on the scale and action On the lower left part of the scale. Only the minimum value of the scale is modified. On the upper right part of the scale. Only the maximum value of the scale is modified. On the center of the scale. Both minimum and maximum values are modified, in the same direction. This performs a translation of the scale On the center of the scale, with Shift key pressed. Both minimum and maximum values are modified, in the opposite direction. This zooms in/out.
	Move (CTRL+F8): When this mode is activated, the mouse pointer has following shape: . Left click on the graph and use the mouse to drag. To quit the Move mode, press the Move button again: this will activate the cursor mode.

Markers group

Features a complete set of real-time markers that help identifying typical signature and points of exception in both time and spectral graphs.

Marker mode: activates the Marker mode. Once the Marker mode is activated, the mouse pointer has following shape: . The mouse pointer can be used to modify the marker position and properties. To quit the Marker mode, press the Marker mode button again: this will activate the cursor mode.

Marker type selection: enables to select the active Marker type. Free marker: The free marker can be positioned everywhere to add a legend in a spectra, profile, 1/n octave and waterfall section. Harmonics marker: The harmonic marker can be positioned everywhere in a spectra and waterfall X/Y sections. Computes and displays harmonic values for the selected trace(s). Peaks marker: The peak marker detects automatically the peaks in the spectra and waterfall X/Y sections. Computes and displays peak values for the selected trace(s). Maximums marker: The max marker detects automatically the maximum in the spectra and waterfall X/Y sections. Computes and displays max values for the selected trace(s). Side bands marker: The Sideband marker can be positioned everywhere in a spectra and waterfall X/Y sections. Displays values for a central frequency and side frequencies (left and right) defined by a delta value. Power band marker: 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. Computes and displays power in signal range defined by start position and delta. 1/n oct data marker: 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. Displays all band values. Kinematic marker: The Kinematic marker can be positioned everywhere in a spectra and waterfall X/Y sections. The Kinematic marker helps identifying the frequencies (or orders) which match the various rotating speed in machineries. These frequencies are linked with a fundamental one (usually the main shaft rotating frequency) by fixed ratio. These ratios depend on the machinery kinematics. Periods marker: The period marker can be positioned in trigger blocks windows. Operates like an harmonic marker but in the time domain. Computes and displays periodic values for the selected trace(s). The periodic marker allows identifying the periodicity and frequency of repeated phenomena identified into time series graphs.

See Marker page for more details.

Waterfall group

The Waterfall group offers a wide range of operation in order to go further in your measurement. It is possible to display XY and YZ sections as well as the extraction section. This group provides general purpose tools about the Waterfall 3D graphs.

	Display Waterfall sections: This multi-action button enables selecting the areas of the Waterfall window to be displayed. The Waterfall window is composed of 4 main areas: 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.
	3D waterfall graph or ColorSpectrum view: Enables selecting the type of view for the Waterfall window. 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. 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. Frequency/time color map: Plot the spectra (or trigger blocks) on 2D map with the color representing the point amplitude. This plot shows the Frequency (Y) Vs Time (X) arrangement. Time/frequency color map: Plot the spectra (or trigger blocks) on 2D map with the color representing the point amplitude. This plot shows the Time (Y) Vs frequency (X) arrangement.
	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 graphs. Waterfall display provides extraction of section from the 3D space.
