=====Force=====
This setting is generally used to set up a uniform time window around the interesting part of the signal such as hammer impact, for example.

[[Image:Filter_builder_09.png|framed|none]]

* '''Window Start''': Starting point of the window as a percentage of the triggered block size of the plug-in using the window. The block size is the plug-in resolution setting value multiplied by 2.56. ex: for 401 lines resolution the triggered block size is 401*2.56 = 1024 samples.
* '''Window Stop''': Stopping point of the window in percentage of the triggered block size of the plug-in using the window. The block size is the plug-in resolution setting value multiplied by 2.56. ex: for 401 lines resolution the triggered block size is 401*2.56 = 1024 samples.

'''Note''': it is possible to adjust the start and stop values graphically by using drag and drop on the graph.

=====Response=====
This setting is generally used to set up a uniform time window around the interesting part of the signal such as the response of an accelerometer after a hammer impact, for example.

* '''Window Stop''': Stopping point of the window as a percentage of the triggered block size of the plug-in using the window. The block size is the plug-in resolution setting value multiplied by 2.56. ex: for 401 lines resolution the triggered block size is 401*2.56 = 1024 samples.
* '''Flat top Start''': Starting point of the window flat top as percentage of the triggered block size of the plug-in using the window. The block size is the plug-in resolution setting value multiplied by 2.56. ex: for 401 lines resolution the triggered block size is 401*2.56 = 1024 samples.
* '''Flat top Stop''': Stopping point of the window flat top as a percentage of the triggered block size of the plug-in using the window. The block size is the plug-in resolution setting value multiplied by 2.56. ex: for 401 lines resolution the triggered block size is 401*2.56 = 1024 samples.
* '''Decreasing point X''': Abscissa of the intermediate point that determines the decreasing coefficient of the exponential function as a percentage of the triggered block size of the plug-in using the window. The block size is the plug-in resolution setting value multiplied by 2.56. ex: for 401 lines resolution the triggered block size is 401*2.56 = 1024 samples.
* '''Decreasing ''''''point Y''': Ordinate of the intermediate point that determines the decreasing coefficient of the exponential function as a percentage of the value of the signal.

* '''Exponential coefficient''': this coefficient is calculated with the coordinates of Decreasing point Y and Decreasing point X.

In this example, it then gives

'''Note:''' a time window can be applied to several plug-in analyzer channels. The modification of the time window values will be applied to all the channels the time window is active.
