5.1.5.2 Power check
Ensure that the
ON
LED turns on. Forward power and modulation readings should
appear briefly on the display. If the RF output is disabled, those readings will be
zero.
When the
PLL
locks to operating frequency, the LOCK LED will turn on.
5.1.5.3 How to enable the RF output
Check output power level and set it to maximum level (unless it has already been
set) from the
Power Setup
menu that you will have accessed by pressing the
following sequence of key:
ESC
(opens
Default Menu
)
⇒
ENTER
(hold down for
2 seconds)
⇒
SET
⇒
use keys to set bar to upper limit.
Check the state of the
Pwr

.
5.1.5.4 Output power level control
IMPORTANT:
The exciter incorporates Automatic Gain Control (AGC) 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. Please
read section 5.3 for more details of RF power modulation.
Access the
Power Setup Menu
pressing the following keys in the order:
ESC
(opens
Default Menu
)
⇒
ENTER
(hold down for 2 seconds).
Use the keys and in the
SET
menu to set transmitter output power; the
setting bar at the side of
SET
provides a graphic indication of power setting; please
consider that the forward power readout provided on the display (
FWD: xxxx
W
) reflects actual output power reading,
which may be lower than regulated
power supply when Automatic Gain Control is running in power supply
limitation mode
(please read section 5.3 about RF power supply modulation for
more details).
Note:
Output power may be set using the
Pwr OFF
control. In this condition, the
output power readout (
Fwd
) on the display will read 0 (zero); the
SET
bar will reflect
any adjustments you make using the keys and provides a graphic indication of how
much power supply will be delivered the moment you return to
Pwr On
state.
