When a function group is selected, the measurements within this group are displayed in the right half of the table. A measurement generally consists of measurement menus and specific configuration menus. A complete graphical overview of all menus of the CMU basic system and the function groups RF and Audio can be found at the end of section Overview - RF Measurements in this online help.
Most of the optional network test function groups are divided into the two independent test modes:
| Non Signalling | Module tests; measurements without transmission of signalling parameters and call setup. |
| Signalling | Measurements with signalling and call setup to the device under test. |
The test modes form the header lines of expandable table sections. A measurement may be available in both test modes of a function group, therefore, to uniquely define a measurement, it is necessary to specify its name, the test mode (if applicable) and the function group.
| Example | In the figure Menu Select, the Power measurement is selected. This measurement belongs to the Signalling test mode in function group GSM400-MS. Another Power measurement belongs to the Non Signalling test mode of the same function group. |
