Techical description

TEX 1000 Light is a compact FM transmitter manufactured by RVR Elettronica Spa for audio radio broadcasting in the 87.5 and 108 MHz band in 10Khz steps, featuring adjustable RF output up 1000 W under 50 Ohm standard.

Has 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 directly connected to the antenna.

Two major features this device are the 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 the male and female connectors or through flat cables terminated by connectors. This design facilitates maintenance and module replacement.

The RF power section 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.

This FM transmitter 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 intefacing with the microprocessor control system, which ofers the following features:

• Output power setup
• Operating frequency setup
• Power output enable/disable
• Power Good feature (User selectable output power alarm threshhold)
• 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 notificzations: ON, LOCK, FOLDBACK and RF MUTE; two yellow LED's indicate power supply malfunction.

The rear panel features the mains input connectors with mains voltage switch 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 signlas modulated onto subcarriers by suitable external coders, such as RDS (Radio Data System) signlas commonly used in Europe.
