Function
of
front-panol
horizontal-block
confroll.
Collector
Sweep
Block
The
PEAK
VOLTS
RANGE
switch
selects
one
of
two
peak
voltage
ranges
for
sweeping
the
collector
of
the
transistor.
In
the
0-20
position,
the
peak voltage
can
be
varied between
zero
and
20
volts
by means
of
the
PEAK
VOLTS
control;
in
the
0-200 position,
the
voltage
is
variable
between
zero
and
200
volts. The POLARITY
switch
determines
whether
posi
tive-going
or
negative-going
sweeps
are
applied
to
the col
lector.
The
DISSIPATION
LIMITING
RESISTOR
switch
con
nects
one
of the indicated
resistance
values
in
series
with
the
collector
to
limit
the
collector
dissipation
and
thereby
protect
the
transistor
from
excessive
power dissipation.
The
value of
resistance
selected
also
becomes part
of
the
tran
sistor
load,
os
explained
under
“Transistor Load Resistance"
on the top-panel
chart.
