ABSTRACT:
A signal measurement system with softkey menus for guiding a user in selecting a desired test setup, including selection and connection of the device to be tested, as well as selecting calibration measurement and test measurement for the device. In response to a given softkey selection, the signal measurement system prompts the user with a set of displayed textual instructions and pictorial diagrams via a user interface to step the user through setup, calibration, and measurement processes. Preferably, a signal processing unit (or analyzer) included in the signal measurement system incorporates the user interface in firmware to guide and aid the user in connecting the device to be tested to the signal measurement system for the desired test, and leading the user through calibration and measurement processes. The analyzer preferably displays the softkey menus, instructional text displays, and pictorial block diagram displays on a cathode ray tube included in the analyzer to guide the user. The displaying of sequential user instructions and diagrams facilitates proper configuration of connections for calibration of the signal measurement system, as well as connections for measurements of the characteristics of devices to be tested.
