DataBRICK II Data Acquisition System

The Data Brick provides reliable, high performance data acquisition in a small, extremely rugged, lightweight package.

Fully Programmable	No need to buy extra plug-in cards or stacking modules. The Data Brick is completely self contained. The sensor power, signal conditioning, offset compensation, etc. are controlled through the graphical, menu driven, host computer software.
Versatile	You program the Data Brick to work the way you want it to work. You select the trigger mode. You select the sample rate. Each channel can sample up to 12,800 samples per second. Up to 524,218 data points can be logged during a test.
Accurate	The Data Brick is self-calibrating for all ratiometric sensors and the software will prompt you through the calibration procedure for other types of sensors.
Reliable	Variable frequency, low-pass, anti-aliasing filters guarantee that your data is not a false representation of what you measure.
Rugged	The Data Brick will continue to gather data while being subjected to repeated accelerations in excess of 100 g.
Flexible	Each Data Brick has 8 differential analog input channels (1 channel is capable of external multiplexing), 4 counter input channels and 1 trigger channel. The software will manage data acquisition from up to 8 Data Bricks.
Simple to Use	The Data Brick is so easy to use that it can be configured for a test within a few minutes.
Real Time	The host computer software offers simultaneous real time display and logging of data.
