TELEMETRIX 400 PHASE CONTINUOUS DIGITAL RF MEMORY (T400PCD)
OVERVIEW
 The Phase Continuous Digital RF Memory (T400PCD) is an innovative, pipeline DRFM product that provides phase continuous dynamic effects. The T400PCD utilizes digital signal processing techniques to smooth RF propagation effects such as dynamic time delay. The unit also provides accurate Doppler effects on the signal modulation as well as the carrier frequency shift. Hence, the range, range rate, and Doppler are properly correlated to truthfully emulate all physics-based effects on the signal. The T400PCD is a modular, expandable, and re-programmable unit which readily enables multipath emulation as well as multiple signal paths from various independent signal sources.

APPLICATION
 The T400PCD provides high fidelity test, training, and EW for radar and communication systems. Programmability and modularity ease adaptation to specific customer requirements.
