5.4.1 Operation Menu (Fnc)
From this menu the user can enable or disable the exciter power supply, set
the deviation display modality and set up the percentage of Forward (PgD) or
Reflected Power Good (PgR)
.
To operate on one of this voices, select the relative line by the
and
buttons,
then press and keep pressed the ENTER button until the command doesn’t come
accepted. In this way the Pwr setting will become from On to Off, or viceversa, and
the Mod setting from “x1” to “x10” or viceversa. To modify the Power Good value
percentage is sufficient, after to have selected the “PgD” or “PgR” voice, set up
the value through the
and
buttons, then confirm with
ENTER.
Menu 4
Pwr
Enables (On) or disables (Off) the power supply of the exciter.
Mod
Display modality of the modulation selectable between “x1” and “x10”.
The indication of the instantaneous deviation is multiplied by a factor
10 in the “X10” mode, so the hatched indicator on the predefined menu
will coincide with the 7.5 kHz value instead of 75 kHz. This display
mode is useful when you want to view low deviation levels such as, for
example, those due to the pilot tone or to the subcarriers.
PgD
Regulation of the Power Good threshold relative to the forward power.
The percentage value of Power Good is referred to the nominal power
of the machine, that is 30 W, not to the supplied forward power. If a value
equal to 50% is setted, it will correspond indifferently to 15 W from the
set up power. The Power Good function is a control and alarm function
on the supplied power. When the output power fall under the threshold
value of Power Good set, the machine modifies the pin state [7] of
“Remote” DB15 connector on the rear panel (figure 6.2 note [9]).
PgR
Regulation of the Power Good threshold relative to the forward power.
The percentage value of Power Good is referred to the nominal power
of the machine, that is 3 W, not to the supplied forward power.If a value
equal to 5% is set, it will correspond to 150 mW indifferently from the
set up power.
NOTE: This alarm does not have effect on any output signal on the
DB15 “Remote” connector, placed on the rear panel of the equipment,
and it works only in presence of systems equipped of telemetry.
