CMU Audio Generator and Analyzer (Option CMU-B41)
1100.4903.12 4.87 E-10
AF Mode
The AF Mode hotkey determines how the input level is defined.
Manual Manual input via AF Max. Level hotkey
Auto Automatic setting according to the average power of the applied
AF signal.
Two independent values can be set for the two applications AF Chan. One (Ana-
lyzer 1) and AF Chan. Two (Analyzer 2).
Note: The AF Mode setting supersedes the corresponding setting in the
Control tab of the Analyzer Configuration menu; see section
Measurement Control (Analyzer Configuration – Control) on p. 4.81 f.

Generator
Level
The Generator Level softkey defines the level of the AF multitone signal.
The generator level settings are described in more detail in section Test Tones
(Multitone Configuration – Tone Def.) on page 4.93 ff.
Display
The Display softkey scales or shifts the graphical display.
Level
Scale
The Level Scale hotkey defines the level scale of the Multitone test diagram (ordi-
nate scale). The level scale merely represents a display configuration that doesn’t
have any impact on the measurement or on the input signal path.
The level scale is calculated from a maximum value (Max.) and a Span:
• The Max value defines the upper edge of the diagram.
• The difference Max – Span defines the lower edge of the diagram.
• The number of horizontal grid lines (corresponding to 10, 15, or 16 cells) and
the ordinate labeling is adapted to the range.
Remote control
no remote control command; screen configuration only
Tone
Scale
The Tone Scale hotkey selects the display range (abscissa scale) of the test dia-
gram. The range comprises 14 test tones which must be in consecutive order. This
condition leaves the following options:
Tone 1 to 14 Display all results between tone 1 and tone 14
...
Tone 7 to 20 Display all results between tone 7 and tone 20
If a tone is within the selected range but disabled in the Tone Def. tab of the con-
figuration menu (see section Test Tones (Multitone Configuration – Tone Def.) on
page 4.93 ff.), the corresponding result is not indicated, i.e. the bar is omitted and a
gap occurs in the test diagram.
Remote control
no remote control command; screen configuration only
Default
Scale
The Default Scale hotkey cancels all display configurations made and activates the
default settings.
