Individual channel modules that plug into the 5800 enclosures condition, amplify, filter, digitize and store the transducer signals. Simultaneous sampling provides excellent time correlation between channels and external events. The digitizer is available with 14, 16 or 24-bit resolution and sample rates up to 10 Million samples per second.
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 long-term 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.
Each channel has two inputs: one for bridges, voltage, RTDs, potentiometers and thermocouples; the other AC coupled with current excitation for transducers with built-in electronics. Signal conditioning includes programmable excitation and completion for 1/4, 1/2 and full bridge, AC-coupling, automatic balance, voltage and four-step shunt calibration, programmable gain and a four frequency, eight-pole filter.
