DESCRIPTION
The
Motorola
Communications
System
Analyzer
is
a
portable
test
instrument,
designed specifically for
servicing and
monitoring
communications
equipment.
Its
functions supersede those of a Service
Monitor,
expanding
the
features
and
capabilities
so that serv-
icing
involves
only a
single
instrument,
rather than
a
host
of separate equipment.
The
R2001D
is
the
standard Communications
Sys-
tem
Analyzer.
The R2002D
has
the added capability
of
an
IEEE-488 Standard
Interface
control bus,
and
the
R2008D
has
the added capability of "Cellular
Radio"
testing.
The
R2009D
adds
both
of
t
hese
capa-
bilities to the basic
unit. By
improving a
technician's
efficiency
and
accuracy,
the
Analyzer
reduces
service
time.
The
Communications System
Analyzer
generates
and monitors signals,
performing
the tests
normally
associated with the equipment
listed
below.

This mini-

is
used
in a mobile

and means the
