Abstract
A graphical user interface implemented with touchscreen technology with associated indicators for a test instrument is provided. A set of indicators is mounted around the periphery of the touchscreen display so that each indicator is associated with a set of labeled softkeys on the touchscreen. Each of the indicators is chosen to indicate a piece of basic information that is necessary to communicate to the user of the test instrument in an unambiguous manner using color, such as the presence or absence of a signal, the presence or absence of an error condition, or a status of the test instrument. Because each indicator is coupled to labeled softkeys in the touchscreen display, an action to press an associated softkey is directly linked to each indicator to allow detailed information to be viewed graphically on the touchscreen display.
