GENERAL DESCRIPTION

The
ADXRS450/ADXRS453
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 satellite boards for several Analog Devices
inertial sensor products. The ISEB connects directly to a PC via
a USB cable, with the USB connection providing both power
and communications to the board. The ISEB is connected to the
satellite board through a ribbon cable. This cable allows the
satellite to be easily manipulated for testing or 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.
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 and gyroscopes. The different
products are evaluated by means of separate GUIs that are custom-
ized for performance and characterization measurements relevant
to the inertial sensor being evaluated.
The EVAL-ADXRS450Z-M/ADXRS453Z-M system contains
the ISEB and the EVAL-ADXRS450Z-S/ADXRS453Z-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
