The HP 70205A Graphics Display (a 3/8-width module) and HP 70206A System Graphics Display(a free-standing instrument with a 9-inch CRT) are menu-driven human interfaces for the HP 70000 Modular Measurement System. They display system configuration information, measurement results, text, graphics, and include built-in trace and marker capabilities. Sofkeys are used to establish an interactive front panel for any modular instrument.
