Diagrams.
Complete
circuit
diagrams
are
given
on
fold-
out
pages
in
the
Diagrams
section.
The
component
number
and
electrical
value

each
component
in
this
instrument
are
shown
on
these
diagrams,
Each
main
circuit
is
assigned
a
series
of
component
numbers.
Table
4-1
lists
the
main
circuits
in
the
7613
and
the
series
of
component
numbers
assigned

each.
Important
voltages
and
waveforms
are
also
shown
on
the
diagrams.
The
portions
of
the
circuit
mounted
on
circuit
boards
are
enclosed
with

Circuit
Boards.
Fig.

shows
the
location
of
the circuit
boards
within
the
7613;
Fig.

shows
the
location
of
circuit
boards
in
the
R7613.
Pictures
of
these
circuit
boards
are
shown
in
Figs.
6-1
through
6-11.
These
pictures
are
located
in
the
Diagrams
section
on
the
back
of
the
page
opposite
the
circuit
diagram,
to
aid
the
cross-referencing
between
the
diagrams
and
the
circuit-board
components.
Each
electrical
component
on
the
boards
is
identified
by
its
circuit
number.
The
color
and
location
of
the
inter-
connecting
connectors
are
also
shown.
The
circuit
boards
are
also
outlined
on
the
diagrams
with
a
blue
line
to
show
which
portions
of
the
circuit
are
located
on
a
circuit
board.

Connector
Color-Code.
The
multi-pin
connectors
used
for
interconnection
between
circuit
boards
are
color-coded
to
aid
in
circuit
tracing.
The
color
of
the
connector
body
matches
the
resistor
color-code
for
the
last
digit
of
the
circuit
number;
e.g.,
P601
is
brown,
P603
is
orange,
etc.
Wiring
Color-Code.
All
insulated
wire
and
cable
used
in
the
7613
is
color-coded
to
facilitate
circuit
tracing.

Resistor
Color-Code.
In
addition
to
the
brown
composi-
tion
resistors,
some
metal-film
resistors
and
some
wire-
wound
resistors
are
used
in
the
7613.
The
resistance
values
of
wire-wound
resistors
are
usually
printed
on
the
body
of
the
component.
The
resistance
values
of
composition
resistors
and
metal-film
resistors
are
color-coded
on
the
components
with
EJA
color-code
(some
metal-film
resistors
may
have
the
value
printed
on
the
body).
The
color-code
is
read
starting
with
the
stripe
nearest
the
end
of
the
resistor.
Composition
resistors
have
four
stripes
which
consist
of
two
significant
figures,
a
multiplier,
and
a
tolerance
value
(see
Fig.
4-2).
Metal-film
resistors
have
five
stripes
con-
sisting
of
three significant
figures,
a
multiplier,
and
a
tolerance
value.
Capacitor
Marking.
The
capacitance
values
of
common
disc
capacitors
and
small
electrolytics
are
marked
on
the
side
of
the
component
body.
The
white
ceramic
capacitors
used
in
the
7613
are
color-coded
in
picofarads
using
a
modified
EIA
code
(see
Fig.
4-4).
Diode
Color-Code.
The cathode
end
of
each
glass-
encased
diode
is
indicated
by
a
stripe,
a
series
of
stripes,
or
a
dot.
For
most
silicon
or
germanium
diodes
with
a
series
of
stripes,
the
color-code
identifies
the
three
significant
digits
of
the
TEKTRONIX
Part
Number
using
the
resistor
color-code
system
(e.g.,
a
diode
color-coded
pink-
or
blue-,
brown-gray-green
indicates
TEKTRONIX
Part
No.
152-0185-00).
The
cathode
and
anode
ends
of
metal-
encased
diodes
can
be
identified
by
the
diode
symbol
marked
on
the
body.
