Abstract
The operating modes and parameters of a logic state analyzer are selected by user interaction with a menu displayed upon a CRT. At the highest level of control the user may specify which menu is of interest, should there be more than one. The selected menu is displayed and contains mode selection fields whose labels indicate the various modes that are presently selected. Different modes are selected by positioning a cursor to the associated selection field and then pressing a mode selection key. Each such activation causes the next mode in a sequence of modes, associated with that particular field, to be the selected mode of operation. A descriptive label or phase corresponding to the selected mode is displayed as part of the selection field containing the cursor. The modes and their associated labels are linked in a cyclic order, and repeated activation of the field select key will cycle through the cyclic sequence indefinitely, revealing to the operator what his choices are, as well as indicating the present choice. The cursor may be positioned in random order among several such mode selection fields, but only one field select key is needed, as its above-described action pertains to whichever field contains the cursor. The cursor may also be positioned to parameter entry fields associated with selected modes, and a collection of parameter entry keys allows entry of associated parameters.
