4.2.5 TILT operating mode.
The TILT operating mode displays on-screen, graphically and numerically, the
difference in level between any four frequencies previously defined as pilots. This
function provides a quantitative measurement about band equalisation.
This function can be applied to forward and to the return paths, according to is
defined in the TILT mode configuration menu (section 4.2.5.1 Tilt mode configuration).
To access this mode of operation
press the TILT key [12]. The screen will
show a bar-graph of the four pilot channels
and the difference in level (TILT) between the upper
pilot and the lower pilot (- 5 dB in the example). When
the pilots are not present or its level is lower than 20
dBµV, the message ‘NO PILOTS’ will appear. Turning the
rotary selector [9] the reference level may be modified.
The pilots may be defined in two ways:
a) By frequency
Using the TILT configuration menu. See section 4.2.5.1 Tilt mode configuration.
b) By channel (only pilots in the forward band).
From the SCAN mode. In order to do this:
1.
Place the marker over the channel you want as low pilot.
2.
Press the SCAN key [11], and the message ‘PILOT 1: PRESS TILT’
will appear at the bottom of the screen.
3.
Keeping the SCAN key [11] held down, press the TILT key [12], and a
message ‘PILOT 1 ENTERED’ will appear as confirmation.
Repeat the steps 1 to 3 for the 3 following pilots.
4.2.5.1

Pressing the CONFIG [14] key will

To change a given parameter turn the rotary
selector [9] until the field is activated (this will
appear shadowed) and then press. The value of
the parameter will be activated and may be
changed by turning the rotary selector. When the value you want appears, press the
rotary selector [9] to validate it.
