5. Quick guide for installation and use
This section provides a step-by-step description of equipment installation and
configuration procedure. Follow these procedures closely upon first power-on
and each time any change is made to general configuration, such as when a new
transmission station is added or the equipment is replaced.
Once the desired configuration has been set up, no more settings are required
for normal operation; at each power-up (even after an accidental shutdown),
the equipment defaults to the parameters set during the initial configuration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and firmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When configuring and testing the transmitter in which the equipment
is integrated, be sure to have the Final Test Table supplied with the equipment ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
5.1 Preparation
5.1.1 Preliminary checks
Unpack the amplifier and immediately inspect it for transport damage. Ensure that
all connectors are in perfect condition.
The main fuse can be accessed from the outside on the rear panel. Extract the fuse
carrier with a screwdriver to check its integrity or for replacement, if necessary.
The following fuses are used:

7. Working Principles
7.1 Panel board
The panel board contains the microcontroller (PIC18F452) that implements the
equipment control software, the display and the other components needed to
interface with the user.
7.2 Telemetry board
This board is designed to inform the user of the equipment operation state. All
input and output signals are available on the DB25 connector.
The same board also features the “INTERLOCK” BNC connector for disabling the
device. By grounding the central pin, the output power is reduced to zero until the
connection is removed.
When an R.V.R. amplifier is used, this connector is linked to the power amplifier
REMOTE or INTERLOCK by means of a BNC-BNC connection. In case of amplifier
faults, the central conductor is grounded thus forcing the machine to enter in
stand-by mode.
7.3 Power Amplifier
The final power stage is enclosed in a totally shielded metal container fastened
in the centre of the device.
The RF signal coming from input power connectors, is measured by input directional
coupler card and is then sent to the final stage that sees to its final amplifications
up to 1000W.
The amplification stage consists of two main blocks with low pass filter inside.
In addition to the actual RF amplification, this circuit carries out the following
functions:
• Control of the power level in output, depending on the setting
• Reduction of the power supplied when in presence of high-level reflected
power
• Measures of the forward and reflected power by using directional couplers
• Measures of the current absorbed by the power amplifier
• Measures of the temperature

PJ1002C-LCD
This board also features an RF sampling of approximately -60dBc (for PJ1002CLCD model) with respect to the output, which is available on a BNC connector
below the transmitter output connector. This sample is useful for verifying the
characteristics of the carrier, but not for verifying those of the upper harmonics.
7.4 Control Board
The main function of this board is to check and correct the MOSFET polarization
voltage of the RF amplifier section.
If no alarms are present, the voltage is adjusted only depending on the set output
power, with a feedback mechanism based on the reading of the power really
delivered (AGC).
The voltage is also affected by other factors, such as:
• Excess of reflected power.
• External AGC signals (Ext. AGC FWD, Ext. AGC RFL).
• Excess of temperature.
• Excess of absorbed current from the RF module.
7.5Low Pass Filter Card
This card provide the l�������������������������������������������������������������
ow-pass filtering of the RF signal in output and measure the
reflected and forward power output.
7.6 Bias Card
This card controls the bias voltage and contains AGC networks for forward power,
reflected power, temperature, current and EXT AGC.
It also controls and corrects the power supply voltage of mosfet.
uesta scheda controlla la tensione di polarizzazione e contiene reti AGC
per potenza diretta, potenza riflessa, temperatura, corrente e EXT AGC. Inoltre controlla e corregge anche la tensione di alimentazione del mosfet
