Control window basics
   SIGVIEW Help Home

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 repaint.

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.

Hiding/Showing 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 display.


Overlay signals

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.
