Signal rulers
The signal rulers (sometimes called cursors) help you measure absolute and relative
signal levels on a scope , XY or spectrum view .
In the scope view above, the two colored squares to the left of the vertical axis are
the ruler drag-handles for channel A. Drag one of these downwards from its resting
position in the top left corner, and a signal ruler (a horizontal dashed line) will
extend from it.
Whenever one or more signal rulers is in use, the ruler legend appears. This is a
table showing all of the signal ruler values. If you close the ruler legend using the
Close button, all the rulers are deleted.
Signal rulers also work in spectrum and XY views.
Ruler tool tip
If you move the mouse pointer over one of the rulers, PicoScope displays a tool tip
with the ruler number and the signal level of the ruler. You can see an example of this
in the picture above.
