DIGITAL RECORDING SYSTEMS FOR UNDERGROUND NUCLEAR TEST DATABryars, John; Smith, Gregory S.; Jaycor; Trilogy Microsystems (International Foundation for Telemetering, 1992-10)A Digital Output Recorder (DOR) system was developed by JAYCOR under contract to Defense Nuclear Agency (DNA) for the recording of high-speed digital data from test hardware exposed to radiation during an Underground Nuclear Test conducted at the Nevada Test Site (NTS) in 1991. Electronics hardware for the system is based on the well-supported Versa Module Europe (VME) bus which has become an industry standard for digital process and control systems. The system collects, identifies, and telemeters the data from several interfaces using the VME bus to a common data collection point above ground. The system was designed with built-in flexibility and expandability to meet digital data recording requirements on future underground tests (UGTs).
