• The function group is indicated to the left of the operating mode:
RF measurements
Audio Analyzer and Generator (with option CMU-B41)
In network test applications, the signalling states that are specific to the
applications are indicated. The corresponding icons are discussed in the
relevant manuals (see GSMxxx-MS etc.).
General settings
The Connect. Control softkey is located to the right of the header of each
measurement or graphical measurement menu. This softkey opens a popup
menu defining the input and output connectors, the external attenuation, the
reference frequency as well as many network-specific settings.
In the Signalling test modes of many network options, the Connection Control
menu is also used to set up and terminate a connection between the CMU and
the DUT.
The Connection Control menu also contains the input path and the trigger
settings for the current function group and signalling state.
Measurement
control softkey
The measurement control softkey (main softkey) controls the measurement
application and indicates its state (RUN | HLT | OFF); see section Softkeys on p.
3.1 ff. Its labeling corresponds to the menu heading. For large measurement
groups that are subdivided into several applications, the labeling indicates the
current application.
The hotkey bar associated to the measurement control softkey provides
parameters to define the scope of the measurement (statistical settings).
Pressing the measurement control softkey twice opens a popup menu providing
measurement-specific settings.
