DESCRIPTION

The 5800 is a rugged, battery operated data acquisition and recording system with high performance, dual-mode signal conditioning. It is typically used for recording transient data in harsh physical environments as would be encountered in explosives and explosive effects testing.

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.

The quantities and sample rates of pre and post-trigger data storage are programmable, enabling the 5800 to be configured according to the characteristics of the data being acquired. Sample rate can be changed during acquisition without interrupting data flow to capture high-speed events, yet have sufficient memory space to record longterm effects. The 5800 can be configured for multiple records, each using the same pre and post-trigger sampling profile. Data is debriefed and transferred to permanent storage by the Ethernet interface.
