Description
—
Type
114
Fig.
3-2.
Type 114 block configuration for
square-wave output.
CAUTION
Do
not
connect
test
probe
ground
clips to
the
com
mon
point
of
the
circuit
board
while
the
AMPLI
TUDE
switch
is
in
either
of
the
negative
positions.
The
best procedure is to
always
connect the
test
probe
ground
clip
to the
main
chassis
and
leave
the
AMPLITUDE
switch
in
the
positive
output
posi
tions.
The
VARIABLE
control
associated
with
the AMPLITUDE
switch
provides
continuously
variable
voltage
amplitude
within
the
ranges
of
the
AMPLITUDE
switch.
Power Supply
The
power
supply
consists
of
a regulated
25-volt
supply
and
an
unregulated 35-volt
supply.
The
25-volt
supply
and
a
10-volt
supply
are
stacked
to
obtain
the
35-volt
supply.
A
rear-panel
switch
is
provided
to
change
transformer
pri
mary
connections
when
switching
from
115-
to
230-volt
operation.
