4. General Description
The TEX30/50/100/150/300LCD, manufactured by R.V.R. Elettronica SpA, are
exciters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 30, 50, 100, 150 and 300 W
respectively into a 50 Ohm standard load.
The TEX30/50/100/150/300LCD are designed to being contained into a 19” rack
box of 2HE.
4.1 Unpacking
The package contains:
1 TEX30LCD,TEX50LCD,TEX100LCD,TEX150LCDor TEX300LCD
1 User Manual
1 Mains power cables
The following accessories are also available from Your R.V.R. Dealer:
• Accessories,sparepartsandcables
4.2 Features
Theseexciterscontainalow-passlterthatreducestheharmonicemissionto
provided for by international standards (CCIR, FCC or ETSI) and can be connected
directly to the antenna.
Two major features of TEX30/50/100/150/300LCD are compact design and user-
friendliness. Design is based on a modular concept: the different functions are
performed by modules that, for the most part, are connected through male and
facilitates maintenance and module replacement.
The RF power section of the TEX30LCD features a MOSFET module delivering
up to 30W output power, the TEX50/100/150LCD features a MOSFET module
delivering up to 150W output power, the TEX300LCD features a MOSFET module
delivering up to 300W output power.
Operating frequency stability is ensured by a temperature-compensated reference
oscillator and is maintained by a PLL (Phase Locked Loop) system. The exciters
will go into frequency lock within 30 seconds after power-on.
The TEX30/50/100/150/300LCD can operate throughout the frequency bank with
no need for calibration or set-up.

5.2.4 Controllo del livello di potenza di uscita
Note: 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, reected 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 exciter 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)reects
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 reect
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.
5.2.5 Changing the Power Good alarm threshold
Change Forward Power Good alarm setting PgD from the Fnc menu as desired
(factory setting is 50%).
5.2.6 Setting equipment I2C address
Change the IIC address in the MIX (Miscellaneous) menu as desired (factory
setting is 01).
5.2.7 Adjustments and calibration
The only manual adjustments are the level adjustments and the audio mode
adjustment.

When setting input sensitivity, please consider that the default menu reports
instantaneous modulation level and an indicator provides a 75 kHz reading. To
ensure correct adjustment, apply a signal with the same level as user’s audio
broadcast maximum level and then adjust using the trimmer until instantaneous
deviation matches the 75 kHz reading.
To set subcarrier input levels, you may use the same procedure and option “x10”
available in the Fnc menu. With this option, modulation level is multiplied by a factor
of10,whichmeansthatdefaultmenubarmeterreectsa7.5kHzdeviation.
A special menu with separate indications of Left and Right channel levels and
relating indicators of nominal levels for maximum deviation (75 kHz) is provided.
