Abstract
An oscilloscope displays a menu consisting of set of field codes and one configuration code set grouped with each field code. Each field code represents an oscilloscope operating parameter while each configuration code represents an alternative oscilloscope operating mode associated with the operating parameter. A configuration cursor is displayed underlining one configuration code in each field thereby indicating the current operating configuration of the oscilloscope. The configuration of the oscilloscope may be changed by first rotating a first control knob, mounted on the oscilloscope front panel, to locate a field selection cursor under a selected field code and then by rotating a second control knob to move the associated configuration cursor under the desired configuration code. The configuration of each field may be altered by selective operation of the two control knobs in this manner. The menu is displayed only when the oscilloscope configuration is to be changed and the two control knobs are used for other oscilloscope control purposes when the menu is not displayed.
