Two windows are "linked" in SIGVIEW if changes in one of them influence the changes in the
other one. For example, if you calculate an FFT sequence from some part of the signal, that FFT
will recalculate and redraw each time you move
through the original signal, zoom it in or
out, change signal values, ... All windows are by default linked to its parent windows. You can disable that link by choosing System control/Unlink window from parent menu option or button in a toolbar. You can
establish that link again by choosing System control/Link window to parent menu option or
button in toolbar.
You can see the current state of links between windows in the Control window. If two windows
are linked, they will be connected with a solid line. If they are not linked, the line will be dotted.
You can also perform linking/unlinking from the Control window’s
