5.2.2 Power-on
Dopo aver effettuato i collegamenti descritti al paragrafo precedente, accendere
l’amplificatore agendo sull’interruttore di alimentazione presente sul frontale.
Accendere anche l’eccitatore di pilotaggio.
5.2.3 Power check
Ensure that the
ON
light turns on. Machine name should appear briefly on the
display, quickly followed by forward and reflected power readings (figure 5.2 - menu
1). If RF output is disabled, these readings will be zero.
5.2.4 How to enable Local mode and the RF output
Check current mode setting and enable
Local mode
(if not already enabled)
following menu path
Fnc
⇒
Loc
⇒
Local
(figure 5.2): if left disabled, the machine
will not accept the next commands.
Check current
RF
output setting and enable output (if not already enabled) following
menu path
Fnc

(figure 5.2 - menu 4).
Check output power level and set to maximum level (if not already set to maximum)
from the Power Setup Menu, which you can call up by pressing these keys in the
order:
ESC
(opens
Default Menu
)
⇒
ENTER
(hold down for 2 seconds)

5.2.5 RF output power level control
IMPORTANT:
The amplifier incorporates Automatic Gain Control and output
power is modulated based on the power level set by the user and actual operating
conditions, such as temperature, reflected power and other parameters. Drive
power must be kept steady at maximum output power capacity. Please read section
5.3 for more details of RF power modulation.
Open the
Power setup menu
(figure 5.2 - menu 2) pressing the following keys
in the order:
ESC
(opens
Default Menu
)
⇒
ENTER
(hold down for 2 seconds)
.
Use
SET
menu and
keys to set the desired amplifier output power; the SET
bar at the side provides a graphic display of set power, whereas the forward power
value shown on the display (
Fwd: xxxx W
) gives actual output power reading,
and may be lower than set power if an Automatic Gain Control is in limited-
power mode
(
