MAJOR
ASSEMBLIES
Should
it
break down, the
Communications
System
Analyzer
is
designed
to
be
serviced
quickly
and
easily.
The
majority of t he
circuitry is on
12
modular, plug-in
circuit
boards
which
have
built-in
test
points.
These
test points help
in locating
the
problem
to a
specific
board.
Simple
plug-in
replacement gets t
he instru-
ment
back
in
service.
A
list
of
all
subassemblies
is given
in Table
1-4.
The
assembly locations
are
shown
in
Figures
1-5
and
1-6.
