DESCRIPTION

The 5800 is a rugged, battery operated data acquisition and recording system with high performance, dual-mode signal conditioning, and is typically used for recording transient data in harsh physical environments as would be encountered in explosives and explosive effects testing. Data recorders may be mounted in 19-inch EIA 310C style frames or enclosures. In the case of the 5871 and 5881, a mounting tray is available that holds up to four modules.

The 5871 and 5881 have self-contained rechargeable batteries. A line operated power supply is available for operating them and charging the battery. The higher capacity 5872 requires an external battery or other power source. Programmable power modes conserve battery power when setting up or waiting for a test.

Ethernet gives systems of multiple recorders a clean and simple interface using commercially available hubs and switches for programming and data debriefing. Control and clock distribution are done by a PCM encoded bus carried on Category 5 or optic cable. Once programmed, only the clock/control bus is required for synchronized data recording.

Data acquired by the 5800 is digitized and recorded in non-volatile, solid-state memory. It records calibration, pre-trigger and post-trigger data. In a typical test scenario, recording of pre-trigger data is initiated by a TTL input, program instruction, or automatic sequencer. A TTL input or on-board discriminator triggers post trigger data recording.
