Unlike other plug-in, the memory of the waterfall depend on the capacity of the PC and others applications running on it. The depth of the waterfall is function of the free memory of your PC, and is limited to around 3 millions samples per DSP. | Unlike other plug-in, the memory of the waterfall depend on the capacity of the PC and others applications running on it.

===Waterfall Operations=== | |||
The Waterfall window 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. | |||
Graphs | |||
From the Display/Graph tab and the 3D group, select the graphs button: | |||
The Waterfall window is composed of 4 mains area: | |||
* '''3D''' Waterfall graph or '''Colormap''' view | |||
* '''XY''' section | |||
* '''YZ''' section | |||
* '''Extraction '''section (allows extracting orders from a spectrum with a tach or extracting a frequency from order spectrum with a tach). | |||

Cursors give information about the displayed Waterfall trace (current X, Y and Z coordinates are available from the ''Infotrace''). | |||
Move the cursors either by using the drag & drop in the 3D view or by using the arrow pad of the keyboard (the cursor mode | |||

must be selected). | |||
'''Tip''': Move the mouse over the cross in the middle of the window and click in order to resize manually the graph window. | |||

====references==== | |||
The waterfall data are arranged in accordance to the active reference. A reference is a scalar value (RPM, DC level, RMS, Parametric input) stored with the waterfall data | |||
Right click on the grey part of the graph.to select the active reference | |||

The displayed data are then sorted regarding the reference value. | |||

====Section manager==== | |||
You can fine tune the section parameters by using the section manager available by right clicking on the Waterfall window. For example, you want to visualize the first order. | |||
Right click in the grey part of the graph and select Section manager. | |||
[[Image:Usersmanual_176.png|framed|none]] | |||
Then choose Order extraction in the type list. Enter the order you want and click on Add. | |||

====Save results==== | |||
This section gets you to select and save the Waterfall results. | |||
Right click on the Waterfall window and select '''Add to result selection'''. A window that allows you to select the results to be saved is displayed: | |||
* The entire Waterfall results | |||
* The extraction section (in this case it is the order 2 section) independently | |||
* The XY section independently | |||
* The YZ section independently | |||
