Operating Menus 
The CMU offers a large variety of operating modes and applications. To ensure quick and easy 
operation, uniform menus have been implemented. They can be divided into three types: 
Measurement menu  Offers the most important settings controlling a measurement and displays the 
main results. 
Popup menu  Provides extended settings for a measurement menu or function group. 
Graphical menu  Displays a measurement trace together with settings and further measurement 
results, contains softkeys and hotkeys used to access measurement control 
settings. 
 
 
 
Measurement Menus 
A measurement menu provides the basic settings controlling a measurement and at the same time 
displays the main results. Together with the graphical measurement menus, measurement menus 
constitute the basic level in the operating system of the CMU. They can only be replaced by other 
measurement menus or graphical measurement menus. To change the menu, the hotkeys at the lower 
edge of the measurement menu are used.
