10.2.a
STATUS sub-menu
The screen for this sub-menu contains the following items:
Dir. Power:
indicates the direct power currently delivered (in the example, 25.0 W).
Refl. Power:
indicates the reflected power currently measured (in the example, 0.0 W).
Mpx
(multiplex) – indicates the peak deviation, expressed in KHz (in the example, 69.1 KHz) and dB, in reference to a deviation of 75 KHz
(0dB = 75 KHz). To change the deviation in function of the modulating signal, the modulation sensitivity must be set via the
MPX SENS
sub-
menu, from the main
SETUP
menu (
2
section 10.3.c).
In addition, the bar indicator graphically shows the last parameter indicated.
This screen shows the most important parameters; as such, it is normally the one displayed during normal use of the
transmitter.
In order to avoid saving accidental settings, when the
SETUP
has been accessed but no operation performed within a certain
period of time, the device will automatically exit the
SETUP
menu and enter the
VIEW
menu, selecting the sub-menu
STATUS
.
To adjust the output power, go to the sub-menu
POWER
under the
SETUP
menu (
2
10.3.b).
10.2.b
L/R sub-menu
The screen for this sub-menu is used to monitor total peak modulation. It shows the following items:
Left
(left channel) – the current level of the left modulating signal, expressed in dB, against the nominal level (in the example, +0.85 dB).
Right
(right channel) – the current level of the right modulating signal, expressed in dB, against the nominal level (in the example, +0.77 dB).
In addition, the bar indicators graphically show the two parameters indicated above (peak value).
Depending on the setting made in the
SETUP
menu, the modulation level can also be viewed via the following screen, which
indicates a solo or a multiplex channel (which share the same channel).
In the example above, the
Right
channel is indicated.
Adjustments can be made to the nominal modulation level via the
SETUP
menu (
2
10.3).
10.2.c
AUX sub-menu
The screen for this sub-menu shows the modulation level for the
Aux
RDS/SCA signal:
