INTRODUCTION
TO
THE
ASPEN
SYSTEM
The
Aspen
ultrasound
system
is
amobile, self-contained
ultrasound
svstem specifically for medical applications.
The
Aspen
system
is based
on
the use of
modular
printed
circuit
boards
(PCBs)
and
subassemblies
known
as
field replaceable
units
(FRUs). This modularization simplifies on-site service
and
repair. No post-delivery
adjustments
or calibrations
are
required for
equipment
operation. In most cases, on-site
maintenance
is accomplished by removing
and
replacing
the
printed circuit
boards
<PCBs)
or
subassemblies.

REVIEWING
SYSTEM
REQUIREMENTS
Reviewing
Environmental
Requirements
The
Aspen
system
is astable, rugged device. However, it
should
receive
the
care given to
any
precision instrument. Make
sure
that
the
system's
environment
is free
of
fumes, dirt,
and
electrical
interference, e.g.,
brush-type
motors
and
large fields of RF energy.
The
systern is designed
to
operate within
the
following
environmental
limits:
