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 filter 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 flat 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).
