Operation 4-3
6. A Numerical Value in a menu entry box represents the current value of that parameter. See the Chan 1 > Vert Center
menu entry box in Figure 4-1a. If the frame of the menu entry box containing the parameter you wish to change is
not highlighted, press the associated menu key to highlight it. Highlighting is indicated by a color change of the
frame of the selection box (white is default). Some menu selection boxes are automatically highlighted when the
menu is first selected.
7. When an entry box is highlighted, you may use any of the data entry controls (spin knob, arrow direction buttons, or
keypad) to adjust the parameter value. Pressing the menu key of a highlighted item deactivates the item and disables
data entry.
8. Numerical Values can either be continuously variable throughout a range, or restricted to a predefined set of discrete
values. For discrete sets, the spin knob and arrow keys are programmed to select only valid values in the set. For
discrete ranges, if you key in an incorrect value, the instrument will automatically select the nearest correct value. If
you input a value outside the range of the parameter, the instrument may respond with the error message ―Number
Entry Over (Under) Limit‖, ignore the entry without error or force the upper or lower limit value without comment.
9. The word MENU appearing in a menu selection box indicates that there is a submenu of additional selections at the
next lower menu level. In the menu shown in Figure 4-3a, for example, when you press the Disp > Format menu
key, you will call up the Disp > Format submenu illustrated in Figure 4-3b. This menu contains two submenus,
Trace Type and Set Color. Press the associated menu to key call up either of these submenus. You can back out of
the menu tree at any time by pressing the PREV function key which will remove one sub-level each time it is
pressed until the top level menu is reached.
10. The word REPORT in a menu selection box indicates that a text display of data related to the associated item is
available. In the example of Figure 4-4a, pressing the Spcl > Sensor Data > CH 1 Sensor menu key will display a
text report similar to the one illustrated in Figure 4-4b.
11. Pressing the CLR data entry key (see Figure 3-1) clears errors, text reports and any entry in progress.
12. Pressing a menu key associated with the Action CENTER, causes the instrument to center the waveform at the
active Time Mark . See the Mark > Set Vert Cntr menu box in Figure 4-5.
These twelve rules apply generally to all the Model 4500B control menus. By becoming familiar with them, you will
expedite instrument operations and avoid errors.
Note Help screens for each menu describe the menu items. See Subsection 4-7 System Keys. Press the HELP
key to access the help screen for the current menu. Press ESC or press the HELP key again to return to the
previous display mode.
In following subsections you will be introduced to the Top Level Menu and operating procedures for the three primary key
groups: System, Function, and Data Entry.
