TEX100LCD/S ELETTRONICA 4. General Description The TEX100LCD/S, manufactured by R.V.R. Elettronica, is an exciter for Frequency Modulated audio broadcasting in a frequency modulation able to transmit in the band between 87.5 and 108 MHz, in step of 10 KHz, with an RF output power adjustable up to a maximum of 100 W into a 50 Ohm standard load. The unit is factory aligned and calibrated at the time of manufacture. Because of this manufacture process, there is no field tune-up or alignment necessary.
TEX100LCD/S ELETTRONICA The RF power section of the TEX100LCD/S features a MOSFET module delivering up to 150W output power. Operating frequency stability is ensured by a temperature-compensated reference oscillator and is maintained by a PLL (Phase Locked Loop) system. The exciter will go into frequency lock within 30 seconds after power-on. The TEX100LCD/S can operate throughout the frequency bank with no need for calibration or set-up.

TEX100LCD/S ELETTRONICA 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. The board is connected with the other machine modules, both for power supply distribution and for the control and measures. 7.
TEX100LCD/S 7.3 ELETTRONICA Telemetry board This board is designed to inform the user of the equipment operation state. All input and output signals are available on the DB15 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.
TEX100LCD/S ELETTRONICA 7.6 Control Board The main function of this board is to check and correct the MOSFET polarization voltage of the RF amplifier section. It also provides the measurement of the absorbed current and contains a circuit for signaling power supply unit faults. 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).
TEX100LCD/S ELETTRONICA 8. Maintenance and repair procedures 8.1 Introduction This section provides general information about maintenance and electrical settings for the TEX100LCD/S exciter. The maintenance is separated into two sections depending on the complexity of the procedure and the instrumentation required for the test to complete the maintenance. 8.
TEX100LCD/S ELETTRONICA 9. Option This section displays views on the variants compared to the basic version to be requested in the order. For more information about the options, rely on the respective user manuals. 9.1 Power UP/DOWN Option (only software) The Power UP/DOWN option modifies the signal receive function for the signals present at the telemetry connector. RF section on / off control signals are treated as control signals for RF output power level to allow for UP/DOWN setting.
