Region of Interest
The waveform display can be expanded either by dragging the region of interest cursor on the Picture
tile or by using the following controls:
H mag allows the horizontal display to be expanded. The default value of 1 represents
normal horizontal magnification. As this value is increased the waveform is
expanded proportionately and, if
ROI

masked to show the region of interest.
The current magnification is displayed in the bottom right corner of the tile.
H offset allows the position within the expanded horizontal display to be changed.

Placing the mouse cursor on the edges
or corners of the region of interest will
display cursors. Dragging on these cursors
allows the region of interest to be set
interactively using the mouse.
The selected region of interest will be
