4.1 General Description
TEX500-LCD and TEX1000LIGHT are compact FM transmitters manufactured by
R.V.R. Elettronica SpA for audio radio broadcasting in the 87.5 to 108 MHz band
in 10kHz steps, featuring adjustable RF output up to 500 and 1000 W, respectively,
under 50 Ohm standard load.
TEX500-LCD and TEX1000LIGHT have been designed for installation in a 3HE
box for 19” rack.
Thesetransmittersincorporatealow-passltertokeepharmonicsbelowthelimits
provided for by international standards (CCIR, FCC or ETSI) and can be connected
directly to the antenna.
Two major features of TEX500-LCD and TEX1000LIGHT 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
femaleconnectorsorthroughatcablesterminatedbyconnectors.Thisdesign
facilitates maintenance and module replacement.
The RF power section of TEX500-LCD uses two MOSFET modules delivering up
to 300W output power each, whereas TEX1000LIGHT features three MOSFET
modules with up to 350 W output power each.
Operating frequency stability is ensured by a temperature-compensated reference
oscillator and is maintained by a PLL (Phase Locked Loop) system. The transmitters
will go into frequency lock within 30 seconds after power-on.
TEX500-LCD and TEX1000LIGHT can operate throughout the frequency bank
with no need for calibration or set-up.
An LCD on the front panel and a push-button board provide for user interfacing
with the microprocessor control system, which offers the following features:
• Output power setup.
• Operating frequency setup.
• Power output enable/disable.
• Power Good feature (User-selectable output power alarm threshold).

4 / 34 User ManualRev. 1.0 - 27/10/06
TEX500-LCD & TEX1000LIGHT
• Measurement and display of transmitter operating parameters.
• Communication with external devices such as programming or telemetry
systems via RS232 serial interface or I2C.
Four LEDs on the front panel provide the following status indications: ON,
LOCK, FOLDBACK and RF MUTE; two yellow LEDs indicate power supply unit
malfunction.
Theexcitermanagementrmwareisbasedonamenusystem.Userhasfour
navigation buttons available to browse submenus: ESC (Sect.6.1 - [6]), , ,
and ENTER (sect. 6.1 - [9]).
The rear panel features the mains input connectors with a mains voltage switch
(see Sect. 6.2 - [30]) to select the appropriate mains input voltage, as well as audio
input connectors and RF output connector, telemetry connector, protection fuses
and two inputs for signals modulated onto subcarriers by suitable external coders,
such as RDS (Radio Data System) signals commonly used in Europe.

Right [17] [16] -13 ÷ +13 dBm
Input level for 75 kHz deviation (0 dB)
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.

contact (sect. 6.2 - [22]) is activated and any external appliances connected to
it are immediately inhibited.
Next, you can review all operating parameters of the equipment through the
managementrmware.
Normally, the equipment can run unattended. Any alarm condition is handled
automatically by the safety system or is signalled by the LED indicators on the
panel or by display messages.
NOTE: Standard factory settings are output power set to upper limit (unless
otherwisespeciedbycustomer)andOFF.

PgD ModiesPowerGoodthresholdforforwardpower.ThePowerGood
rate is a percent of equipment rated power (500W for TEX500-LCD and
1000 W for TEX1000LIGHT), not of forward output power. This means
that this threshold set at 50% will give 250 W and 500 W, respectively,
regardless of set power level. The Power Good feature enables output
power control and reporting. When output power drops below set Power
Good threshold, the equipment changes the state of pin [7] of the DB15
“Remote”connectorlocatedontherearpanel(gure6.2-[28]).
PgR ModiesPowerGoodthresholdforreectedpower.ThePowerGood
rate is a percent of equipment rated power (50W for TEX500-LCD
