The COFDM Series brings a new level of digital performance and reliability to video and audio collection. Available in P, L, S, and C–Bands, the DR-100 provides high quality demodulation of COFDM digital video and audio signals. The integral LNA and high-selectivity IF filters guarantee reliable receiver operation in harsh RF environments. An optional security feature guards against unauthorized intercept.

Receiver parameters are controlled from the front panel user interface. Frequency selection, COFDM mode, and encryption key codes are accessible through a front panel push-buttons and an easy to read multi-line VFD. Two balanced audio outputs and one data channel are standard. Both NTSC and PAL analog output formats are supported. Built-in speakers and a headphone jack facilitate easy audio monitoring. A LAN connection allows extended remote control.

Packaged in a compact and rugged housing, the construction lends the COFDM Series to applications where quick set-up with a minimum of external equipment is desired. The COFDM Series receiver includes a universal AC power supply and may be operated from commercial power or batteries. Front panel connectors include a monitor video output and dedicated A/V outputs for recording. Additional features are contained on a comprehensive rear panel 25-pin connector for quick and easy integration into any system without expensive specialized connectors.

The COFDM Series digital receiver is well suited for video collection applications in Homeland Security, surveillance, law enforcement, military UAV, RPV, UGV and MOUT, as well as airborne data/telemetry.
