Part A — Getting Started 71Grid ScalingWhen the grid is locked, the scaling factors controlling how much data is visible on the screen (thedistance between consecutive major lines of the grid and a fixed location for one of the lines of the grid)are specified differently. When the grid is unlocked, these scaling factors do not affect the grid.The Grid Spacing option specifies the scaling factors and whether or not to “Show minor divisions” onthe grid display. Changing these values only affects the grid display, not how the waveform is scaled.• Vertical grid: the total range of vertical units displayed per track is specified (Major division) alongwith the first value that should be displayed (First grid line).• Horizontal grid: the scaling factors are specified in how many seconds of data should be visible onthe screen (Major division) and the time offset of the left hand side of the display (First grid line).• Settings can be applied to a selected channel or all channels. (Controlled by checking orunchecking ‘Apply to all channels”).Adjust Grid SpacingTo modify the horizontal and/or vertical grid spacing, choose “Display > Adjust grid spacing.” This willgenerate the aforementioned dialog for modifying the locked axes of the selected waveform. (“Lockvertical grid” and “Use channel specific horizontal grid” must be enabled in order for the gridline fields tobecome active). Enter the desired values and click OK.• Settings can be applied to a selected channel or all channels. (Controlled by checking or unchecking‘Apply to all channels”).The following Grid items can also be selected by right clicking with a graph channel and using thecontextual menu.Grid: Toggles Grid display on and off.Adjust grid spacing: Use to change Gridspacing for one or all channels (divisionsbetween gridlines and position).Grid Options: Use to change Grid display forone or all channels (Color, width, style, dashlength, dash spacing, and scale adjustmentposition).Grid Preset: Use to create /save custom Gridpresets and organize them in a list.
