43. Point the mouse at the up or down arrows on the Joydisk and press the left
button. Notice that the data does not scroll and that the instrument beeps at
you telling you that you cannot scroll data using the up or down arrows.
If the timing menu has several channels of data displayed that fill up more
than the window can display, you can use the up or down buttons on the
Joydisk to position the channels you want to view on the screen.
44. Point the mouse over the timing data just inside the right edge of the window
and press the left button. The cursor will move towards the pointer location.
45. Press the left button a few more times. The data will scroll every time you
press the button.
You can also use the function keys at the bottom of the menu to further define
your display data or to search for specific data. For more information on the
features of the Timing menu, refer to the acquisition module user manual.
In addition to the Timing and State displays, you can also view data in a
Disassembly menu or Graph menu. The Disassembly menu has features similar
to the State menu and will not be discussed in this tutorial. In most cases you
will want to use the Disassembly menu with one of the microprocessor support
packages. For detailed information on the Disassembly menu, refer to the manual
that came with your microprocessor support package. Refer to your module user
manual for information on the Graph menu.
Split Screen Display
An important feature of the Display menus is the capability to display a
split-screen menu. In other words, you can create a Display menu to show part of
the data as Timing data and the other data as State or Disassembly data.
1. While still in the Timing menu, select function key F2: SPLIT DISPLAY.
A new overlay appears giving you the choice of how to split the data.
2. Verify that Timing is highlighted for the Window 1 data and State is
highlighted for the Window 2 data. Change the selections if they are
different.
3. Select function key F6: SPLIT VERT; you have the choice of splitting the
screens horizontally or vertically.
Some new information and new function keys appear letting you define the
ratio of the window widths. You can use function keys F3 or F4 to change
the ratio. You can also lock the cursors to track between the two windows.
4. Select function key F2: LOCK CURSORS to lock the cursors together
(locking the cursors allows the cursors in each window to track each other
over the same data sequence).
