GENERAL DESCRIPTION
The iMEMS® ADXL346 inertial sensor evaluation system
is an easy-to-use evaluation tool targeting bench or desktop
characterization of Analog Devices, Inc., inertial sensor
products. The system consists of the inertial sensor evaluation
board (ISEB), or main board, and a satellite board for any
Analog Devices inertial sensor product. The ISEB connects
directly to a PC via its USB, where the USB connection provides
both power and communications to the board. The ISEB then
connects to the satellite board through a ribbon cable. This
cable allows the satellite to be easily manipulated for testing or
for being separately placed into an environmental chamber for
temperature or humidity testing. Separating the boards
mitigates corruption of data due to the temperature and
humidity effects of other components.

WARNING AND LEGAL TERMS AND CONDITIONS.

Figure 1. Inertial Sensor Evaluation System
The ISEB is a universal main board and is intended to be used
with various satellites of Analog Devices inertial sensors,
including analog and digital accelerometers, as well as gyroscopes.
The different products are evaluated by means of separate GUIs
that are customized for performance and characterization
measurements relevant to the inertial sensor being evaluated.
The EVAL-ADXL346Z-M system contains the ISEB and the
EVAL-ADXL346Z-S satellite. Also included is a USB A to Mini-
B cable to connect the ISEB to a PC and an 18-inch, 20-pin
ribbon cable to connect the ISEB to the satellite. A CD is also
included with the necessary drivers and executables to use the
system and to quickly begin evaluating the ADXL346.
