CORDON Series Digital Video Transmitters
CORDON series compact digital video transmitters are designed to transmit high quality audio and video signals, and telemetry data by wireless with COFDM modulation.
COFDM modulation and digital diversity reception provide high image stability under poor signal propagation conditions: for multipath transmission and signal fading, during movement and for non line-of-sight conditions.
Digital video transmitters are developed for variety of fields. They differ from each other in their design and special functional capabilities. Due to compact size and high performance, CORDON digital video transmitters can be successfully used in portable robot vision systems.
Video transmitters are flexible for their parameters tuning which enable to increase the signal’s transmission range and to change video image quality and signal delay. Optimizing of the settings can significantly improve work of the system. For example, if ultra-narrow band mode is activated, it can increase transmitting range by several times without transmitter output power increase.
CORDON Tx/Rx programmer can be connected to the transmitter that allows frequency channels switching without using a computer and select between preprogrammed configurations on the spot.
Transmitters are designed to operate with different types of antennas of the appropriate frequency range, including those produced according to customer requirements.
All of the video transmitters are compatible with CORDON series video receivers of proper frequency range.
