5.2.2 Power-on
When powering-on the transmitter the first time, perform the operations below to
work efficiently in less time as possible.
1
Turn ON the exciter using the front switch.
2
Set the output power of the exciter to zero.
3
Set the exciter frequency to the working
value.
4
Turn on the amplifies using the front switch.
5
On HC2 combiner rotate the RF PWR ADJ
trimmer in counter clockwise to adjust the
power at minimum.
6
Set the amplifies on LOCAL: press “ESC”
key then select “Fnc” menu then change to
LOCAL if necessary.
7
Press “ESC” key until the display shows the
main screen (FWD and RFL readings).
8
On amplifies, press “Enter” key and keep it
pressed until the first row in the display
shows “Set: ||||||||||||||||||||||||||||””
9
Adjust the bar to mid scale using the arrow
keys and press the “Enter” key
.
REPEAT PROCEDURE (STEPS 6, 7, 8, 9)
FOR ALL AMPLIFIERS
10
Put the output power of the exciter verifying
that each PA has at least
25W
. To check it
press “ESC” key then select “Pwr” menu
then press down arrow to visualize the
measure.
11
Press “ESC” key
until the display shows the
main screen (FWD and RFL readings).
12
Following the procedure on point (8), slowly
raise the power output of amplifies until
reaching the desired value. Raise the power
alternatively on the amplifiers, to avoid high
values of unbalanced power (rej pwr) on RF
combiner.
13
On HC2 combiner rotate the RF PWR ADJ
trimmer in clockwise to increase the power.
To use, then, to reduce the power of the
system.
14
After ten minutes, readjust the output power
of the amplifier(s), it will be lowered due to
heating.
15
Repeat the procedure if the carrier frequency
is changed.
