The
Type
575
is
an
extremely
versatile
instrument
that
can
be
used
to
make
several
tests
on
a
transistor. Its
full
utility
can
only
be realized,
however, when
the operator
under
stands
the
function
of
each
of
the
front-panel
controls.
The
front-panel
layout,
shown
in
Fig. 2-1,
is
quite
simple
and
logical,
and
can
be
divided
into
five
main
blocks.
These
blocks
contain
the
controls
for
the
Vertical
Amplifier, the
Horizontal
Amplifier,
the Collector
Sweep,
the
Base
(or
Emit
ter)
Step
Generator
and
Amplifier,
and
the
Transistor
Test
Panel.
The
location
of
each
section,
as
a functional part
of
the
instrument,
is
shown
in
Fig.
2-2.
Notice
the
front
panel
is
in
two
colors...
red
and
blue.
Those
parts
of
the
panel
etched
in
red
refer
to
the
Collector
voltages
and
currents,
and
those
parts
etched
in
blue
refer
to
the
Base
voltages and
currents.
However,
when
testing
a
transistor
in
the
common-base
configuration,
the
emitter
is
stepped
with
voltage
or
current;
in
this
case,
the
blue
print
ing
on
the
front
panel
refers
to
the
Emitter
rather
than
the
Base.
Vertical
Block
The
Vertical
block
contains
a
24-position
Vertical Selector
switch
which
selects
the
type
of
signal, and
in
some
cases
COLLECTOR
SWEEP
