X and Y Markers
Vertical (X) or horizontal (Y) markers are available in HP BenchLink/Arb to assist you in creating and modifying waveforms. Select
Edit X Markers or Edit Y Markers or click their icons to display the X or Y markers. When the markers are first displayed, your cursor will be in the ‘marker’ mode. The markers can be moved by clicking the mouse on any of the markers and dragging them to the desired location or by using the left and right arrow keys. The X or Y marker positions and the difference between the X or Y marker position is displayed in the Status Bar at the bottom of your HP BenchLink/Arb screen. Markers can be disabled by selecting the appropriate commands from the Edit Menu or by clicking their icons on the Palette Bar.
Markers can be set and held in a specific position by clicking the Thumbtack icon or by selecting Edit Set Thumbtack from the Menu Bar. Thumbtacked markers can be used to confine the editing area or to alter a standard waveshape segment using freehand or line drawing mode. Drawing is permitted only in the area between the markers and must be started in the marked area. Clicking and drawing outside of this area is ignored.
Grid
The waveform edit window contains horizontal and vertical gridlines. To change the spacing of the horizontal and vertical grid lines select View Grid... from the Menu Bar.
The spacing of the vertical (up/down) grid lines is directly affected by the View Grid... command. the horizontal spacing (left/right) of the grid lines is automatically adjusted to standard values (such as 0, 0.25, 0.5, 0.75, or 1.0).
