The EX transmitter consist of plug-in modules, connected together through a mother board, mounted inside a 19" 3HE rack cabinet. It is very versatile through a wide range of modules types that could form several configura-tions. A multifunctional display permits the visualization of all the operating parameters: output power, video level, audio level and operating voltages. All units are provided with remote control interface, RS 232 RF monitor and in-out reference (5 –10 MHz). Synthesized oscillators and broad band amplifiers enable fast and easy frequency changes. The MOSFET techno-logy guarantees high efficiency and an excellent linearity on the entire band.
