Radar System
PRODUCT DESCRIPTION
CST3000 transmitters are full solid-state, modular, multipurpose transmitters offering a high level of performance and a high degree of reliability for continuous transmission, 24 hours a day.
They are specially designed to be remotely controlled, through Ethernet connectivity, making it suitable for local or remote operation via a standard PC.
The output power ranges from 1kW up to 10 kW. The renewed, highly modular, design of the power stages provides a high level of redundancy.
The transmitters incorporate the most advanced technological improvements and comply fully with the latest international radio regulations.
The use of DSP technology in the frequency synthesizer allows virtually any modulation mode to be implemented, including protocols for high-speed data used in ground-to-air or naval applications.
The frequency range extends from 450 kHz to 30 MHz, making the transmitters ideally suitable for NAVTEX broadcasting, shore-to-ship, or ground-to-air communications.
CST3000 transmitters are housed in standard 19-inch subracks or cabinets. The included full protection against misuse or operational failures makes them highly reliable.
Extensive BITE functions facilitate servicing and maintenance. The accessibility of all of the modules and printed circuit boards has been optimised to make maintenance as easy as possible. And, given that the transmitters are fully transistorised using the latest MOSFET technology, maintenance can be carried out in complete safety.
