RF AMPLIFIER MODULE DESCRIPTION The RF Amplifier Modules place in the TXUD4000ATSC Transmitter station are equipment designed to simplify transport and installation. Born to ensure high working reliability they excel also for their great performance. Thanks to the excellent linearity of the amplifiers, achieved with the use of the state-of-the-art LDMOS (UHF) technology, these equipment allow excellent performance both with analog and digital TV signals.
- replace the analogue Cxciter with a DVB-T ones. If you use a DVB-T Modulator with IF output you can use the IF VEGA input; - the output power should be around 1/4 (in DVB-T mode) or 1/3 (in ATSC mode) of the analogue rated power (for example: the 5kW = 1.2kW rms in DVB-T mode or 5kW = 2.0kW rms in ATSC mode).

elliptical response. It can be tuned on all the channels of the UHF TV band (470 - 862MHz) and according to all worldwide standards (6 to 8MHzbandwidth). The elliptical response having two deep transmission nulls makes a very efficient digital TV channel filter response. Tunings (T1, T2, T3, T4, T5, T6) can be quickly moved after loosening the two clamps dowels with a no. 4 Allen wrench. To move tunings, make use of an elastic hammer and a suitable fork when upwards shift is needed.
The transmission nulls shall be placed at the following frequencies, with the aid of the indicated frequency spans, giving the nulls at the 2nd and 9nth division. • Transmission zeroes K25 = C.F. ±4.3MHz (Span = 10.75MHz) • Transmission zeroes K16 = C.F. ±7MHz (Span = 17.5MHz) NOTE: all frequencies above are referred to DVB-T 8MHz standard: 6 and 7MHz standards simply require to accordingly proportionate all values. 2. Preset the coupling links K12, K23, K34, K45, K56, K25 and K16 at middle value, i.e.
• The first dip is related to T1/T6 • The second peak is related to K12/K56 • The second dip is related to T2/T5 • The third peak is related to K23/K45 • The third dip is related to T3/T4 • The fourth peak is related to K34 - Tune repeatedly the filter starting from the outside to the center, witch corresponds to follow the time domain graph starting from left to right.

AMPLIFIER CONTROL 1.1 DESCRIPTION The Amplifier Control (AC) module is the equipment that allows to monitor and manage from a single location a modular transmitter, composed by several combined amplifier modules (AM). The AC continuously monitors the status of the AMs and highlights any anomaly, it monitors the powers in antenna (forward and reflected) and the unbalancing, if any, showing all of the parameters on the display and through the status LEDs.

Section 2 - Installation Contents: 2.1 Preliminary operations 2.2 Operating environment 2.3 First installation 2.
2.1 PRELIMINARY OPERATIONS No wiring is necessary because the device is already installed and correctly connected to the power supply and other parts of the transmitter. In case a new AC has to be installed, check all connections with the help of the diagrams and tables in this Section. Correct installation of the equipment is important for maximum performance and reliability. Before switching on and powering the transmitter, make sure that all connections are correctly made.
DRIVER1/2 Power Supply The transmitter can be wired so that the exciters are directly fed by the AC. The advantage of this configuration is the possibility to control the whole transmitter, Amplifier Modules and drivers, from a single point, that is the AC. Using the adequate male-female cord, connect the power supply of the driver to DRIVER1 POWER connector, for combined transmitters; connect the power supply of the drivers to DRIVER1 POWER and DRIVER2 POWER connector, for TV separated transmitter.
antenna and keep it constant over time, by increasing or decreasing the internal gain. In case of faults in the high-power amplifier stage, the AC stops the AGC in order to prevent any possible damage. AMPL RS485 In a high-power transmitter there are a number of Amplifier Modules (AM) which RF outputs are combined in order to provide the required total high power.
RS232 On the front panel of the AC there is a D-SUB9 female connector used to control the transmitter from a PC, using a standard RS232 serial connection. For more information about remote control option, contact the Sales Department of Elettronika S.r.l. or the local distributor. The pin-out of this connector is DCE-type and can be connected to a PC using a direct cable. This connector can also be used to update the firmware of the AC. This operation should only be performed by qualified technicians.
Switching on and off the transmitter by means of two switches on pins 1 and 14 of the telemeasures connector 66
Section 3 - Operations Contents: 3.1 Switching On the Amplifier Control 3.2 Operation 3.
3.1 SWITCHING ON THE AMPLIFIER CONTROL After having made sure of the wiring, the transmitter can be switched on by using the mains switch on the rear panel. The very first time the transmitter is switched on, set the POWER button on the front panel to 0, which means transmitter off. The display will show for a few seconds an introduction animation, displaying the kind of transmitter and the firmware version. During this stage, all LEDs light up and the buzzer sounds in order to check that it works.
exciters). If the alarm ends, the transmitter is automatically switched on again. Fan Control In case of fan alarm, that is when the FANS CONTROL shows that they are not working properly, the AC switches off the AMs and exciter(s) after a few seconds, but keeps the fans on, unlike the Interlock alarm. If the alarm was due to a temporary block or failure and the fans restarts working, the AC automatically switches on the AMs and exciter(s) again.
hard to read, the contrast can be adjusted by acting with a small screwdriver into the hole on the frontal panel marked with the symbol. The main screen is similar to the one in figure below. It may change depending on the transmitter, for instance depending on the number of AMs and unbalancing. Alarm Window The alarm window may contain three icons indicating anomalies in the operation of the transmitter. The first icon on the left represents the status of the Interlock.
Temperature and frequency window The temperature shown on the display of the AC is the internal temperature of the device and can be considered as a good estimation of the temperature inside the rack. The indication of the frequency is only present for some transmitters, and allows to keep into consideration the different gains of directional couplers with frequency. It can be set from the Settings menu.
(130 events). If the list is full and a new event occurs, the oldest event in the list is deleted to make free space to the new one. Each event has an associated number and contains date and time, concerned module and description of the event. If the event refers to an alarm condition, a bell icon is displayed on the right. The pages of the list can be scrolled using the arrow buttons. Press ESC to return to the main window. To delete all events in the log, press the ESC and RET buttons at the same time.
Buzzer The AC uses the buzzer in case of malfunctioning or situations in which the attention of the user is required. During tests or maintenance it may be useful to disable the buzzer using this menu. Generally speaking, it is better to reactivate it during the normal operation of the transmitter.. Log Mode The log is a very important feature as it allows the user to know the details of the alarms and events occurred to the transmitter, even if it is unattended.
Thresholds Each RF power monitored by the AC should be below a given maximum threshold. In case a value is beyond the threshold, the AC indicates an alarm condition. The values of the thresholds are displayed in the Thresholds menu. Clock/Date This menu is used to set the current date and time. Once the changes are confirmed by pressing the RET button, the AC synchronizes all of the AMs of the transmitter. Backlight The display is provided with a backlight.
