Tilt Operating Mode - Promax 10 premium Guía De Usuario

USER'S MANUAL. PROMAX-10
d) REF. LINE
It permits to activate / deactivate and to define the reference line level in 1
dB steps from 20 to 120 dBµV (dBµV units). This line appears on the
spectrum representation and also it is the threshold value for the impulses
detection in the TRANSIENT mode (only if its value is under 60 dBµV).
e) STOP. FREQ
It defines the maximum frequency for the transient detection.
To leave the configuration menu of the SPECT mode, just press the key of the
operating mode you wish to access.

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.
