Signal Scope

Signal Scope is a specialization of the Perun Scope component custom-made for displaying and visualization of live signals.

The following functionality is specific for Signal Scope component:

• Tracker is the vertical line showing the extent of newest data on the plot. It is relevant only when showing live signals, during an active Real-Time Data-Acquisition session. In such occasions, the signal buffer may contain both samples of the newest data frame, and samples of the previous one. The samples of the last frame are stored first, and the older samples follow. The Tracker indicates where one stop and the other start. Therefore, parts of the signal shown left of the data tracker are the most recent ones, while parts of the signal shown on the right side of the tracker are older.

• Zooming and panning functionalities are horizontally constrained. It is impossible to zoom or pan outside the time-span of the shown signals.
