This section provides a survey of the CMU's operating concept. This includes a description of the basic menu types, the selection and setting of parameters, and a general discussion of measurement control. The operating menus in the CMU basic system, the RF function group, and optional function groups are presented in an overview at the end of this section and described in greater detail in the section Functions and their Applications.
| Operating concept | The CMU was designed for easy, intuitive operation. All menus rely upon a limited number of controls with analogous or identical function. Basic settings are discussed in section Overview - Measurement Control . |
| Basic elements | The CMU is operated via softkeys and tables. Softkeys provide a fast access to the instrument functions. Tables facilitate the management of larger amounts of data. |
| Flexibility and
uniformity |
The CMU permits to switch over between various operating modes (multi-mode operation). For this purpose, it is possible to change between the menus in almost any instrument state. The different function groups (RF, GSMxxx-MS etc., see also separate operating manuals for network test applications) can be operated in the same way; measurements of the same type belonging to different applications are standardized. |
