Control window enables you to work easily with many signals or analysis windows at the same
time. Each signal, analysis window, 3D graphics or instrument created while working with SIGVIEW is represented with its icon in a Control window.
Icons are connected with solid lines to show a signal flow through the system. A dotted line
shows that signal link is not active and changes in the parent will not cause child window to
Selecting in Control window
You can select or unselect icons by clicking on them with the left mouse button. Every function
you perform in the Control window (for example FFT, Time-FFT, Extract from-to,...) refers to
selected icons, i.e. windows they represent. For faster selecting or unselecting, click right mouse
button in the empty part of the Control window and choose some of the selecting options from
context menu (Select all, Unselect all, Invert selection,...).
Operations on single windows
Click right mouse button over some icon and a context menu will appear with some important
functions for the window it represents. If you choose one function from the menu, the result will
be just as if you have chosen that option for the window itself.
Operations on multiple windows
After you select any number of icons you will be able to perform some of the available actions on
all of them (if they all support the function). the fastest way to do so is to open a context menu in
the empty part of the Control Window. It will show you various applicable functions which can be
performed on all currently selected windows.
Click right mouse button over the empty part of the window and context-menu will appear with
Hide and Show options. Choosing one of these options will hide or show all selected windows.
Hidden windows will have a "H" letter near its icon in the Control window. This can be helpful if
you need some temporary windows in your analysis but you don’t want them to take place on the
If you select more than one icon in the Control window, a two additional options will appear in a
context menu: Show selected as overlay and Show selected in one window. Both operations will
create a new window where selected signals will be shown in the same coordinate system (as
overlay) or in separate coordinate systems in one window For general information about this
feature, see Overlays.
Playing multiple signals simultaneously
You can also use VCR-like
functions on multiple signals selected in the Control window. It will
allow you to play more signals at the same time and simulate real-time comparison or
combination between them. If your sound card supports that feature, you will be able to hear both
signals mixed at the same time.
Calculating Average from two or more signals
There is also a special functionality of the Signal averager window when used from the Control
window. To use it, select two or more signals in the Control window and choose Signal
tools/Averager context menu option. A new signal window will be created, representing average
value from all selected signals.
Concatenating multiple signals
To concatenate multiple signals into a new signal, you can choose "Concatenate all selected
signals" context menu option. A new signal will be created, consisting of all selected signals
concatenated in one signal with the sampling rate of a first signal.
