GENERAL DESCRIPTION
The
Type
175
Transistor-Curve
Tracer
High-Current
Adap
ter
enables
the
Type
575
Transistor-Curve
Tracer
to
plot
and
display
the
characteristic
curves
of
high-power
tran
sistors.
Basically
the
Type
175
High
Current
Adapter con
tains
a Collecter
Sweep circuit
and
a
Step
Amplifier
which
are
used
in
place
of
those
in
the
Type
575.
These
circuits
are
capable
of
handling peak collector curents
om
more
than
200
amperes
and
base
currents
up to 12
amperes.
The Type
175
also
contains
the
necessary
voltage
dropping
and
current-sampling
resistors
for
translating these
high
currents
and
voltages
into
deflection
voltages
suitable
for
display
on
the
Type
575
crt.
The
Step
Generator
and
the
Horizontal
and
Vertical
Am
plifiers
in
the Type
575 perform
the
same
functions
when
the
Type
175
is
used
with
the
Type
575 as when
the
Type
575
is
used by
itself.

INSTALLATION
INSTRUCTIONS
If
your Type
575
Transistor-Curve
Tracer
has
not been
modified
for
use
with
the
Type
175
High-Current
Adapter,
it
will
be
necessary for
you
to
do
so
before
the
two
can
be
operated
together.
The
following
instructions
tell
you
how
to make
this
modification
and how
to
mount
the Type 575
on
top
of
the
Type
175
to
make a
convenient
operating
unit.
Modification
Drill
five
holes
in
the
upper
left
corner
(facing
the
instru
ment from
the
rear)
of
the
rear panel
according
to
the
dimensions
shown
in
Fig.
6-1.
Mount
the
Type
175
inter
connecting
plug
and
harness
in
the
holes
and
connect
the
wires
as
shown
in
Fig.
6-2
and Fig.
6-3.
Fig.
6-1.
Location
and
dimensions
of
holes for
mounting
intercon
necting
plug
in
Type
575.
Mounting
Remove
the
two
cabinet
bolts
from
the
bottom
front
of
the
instrument and replace them
with
the
two hinge
bolts
pro
vided in the
modification
kit
(see
Fig.
6-4).
If
necessary,
enlarge
the
holes
in
the
Type 575
with
a
3/
16-inch
drill.
Set
the
Type
575 on
top
of
the Type
175
so
that
the
hinge
bolts
fall
into
the
sockets in
the
front
mounting
feet
on
the
Type
