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
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.
