The incorporation of Pulse Descriptor Words (PDWs) adds a novel dimension to the capabilities of the Model 875. PDWs, which contain crucial parameters like pulse duration, amplitude, frequency, and timing information, can be uploaded into the internal memory via Ethernet or USB communication ports. During playback, these PDWs are dynamically translated into modulation parameters, resulting in a stream of modulated radar signals. This real-time translation and playback of accurately timed PDW sequences prove invaluable, particularly in complex radar simulations.

Seamless Real-Time Playback

Engineers and researchers can rejoice in the convenience offered by the Model 875's Fast Control Port (FCP). Individual PDWs can be fed into the internal memory in real time, allowing for immediate playback. This dynamic feature facilitates rapid parameter changes, enabling a high degree of flexibility during the design and verification of complex radar simulations.
