Overview

The DAQ848 instrumentation recorder is a data acquisition system that features high performance analog-to-digital conversion with associated signal conditioning. This instrument, coupled with a dedicated host computer running the Windows NT operating system, combine to form a complete data acquisition system.

The maximum sampling rate of the DAQ848 is 200,000 samples-per-second. Each channel contains a sigma-delta analog-to-digital converter. The sigma-delta architecture provides inherent filtering and synchronous sampling without the need for costly sample/hold amplifiers or sophisticated analog anti-aliasing filters. The DAQ848 can support aggregate data rates up to 6.4 megabytes per second.

Each channel has independently programmable input spans from ±10mV to ±10V, which is provided by an instrumentation amplifier on the input. The DAQ848 has 10 selections for the voltage-input range to ensure full utilization of the ADC´s dynamic range. An option is available to allow voltage input ranges of up to ±15 V.
