both
the Type
114 and
the oscilloscope (see
Section 1
for
external
trigger
characteristics
required).
2. Obtain
an
externally
triggered
sweep
on
the
oscillo
scope.
3.
Connect
a
coaxial
cable
between
the TRIGGER
OUT
PUT
connector
of the
Type
114
and
the
vertical input
of
the
oscilloscope.
4.
Turn
the
Type
114
PERIOD
switch
to
EXTERNAL TRIG
GER.
Set
the
WIDTH
switch
to
100 µS. Turn
the
WIDTH
variable
control
to CAL.
Set
the
oscilloscope
VOLTS/CM
switch
to
1
volt.
Set
the TIME/CM
switch
to
.1
mSEC.
5.
Set
the
Type
114
TRIGGER
switch
to
TRAILING
EDGE.
A
narrow
trigger
pulse
approximately
3
volts
in
amplitude
should
be
visible
approximately
1
cm
from
the
start
of
the
oscilloscope
trace.
6. Turn
the
WIDTH
—
VARIABLE
control
and
note
that
the
displayed
trigger
pulse
can be
delayed
from
10 µ
sec
to
more
than
100
µ
sec
from
the
start
of
the
trace.
By
using
the
5
basic
ranges
of
the WIDTH
switch
and
by
turning
the
as
sociated VARIABLE
control,
it
is
possible
to
delay
the trigger
pulse
over
a
range
from
approximately
150
nanoseconds
to
10
milliseconds.
Switching the
Power
Transformer Primary Con
nections
A
switch on the rear
of
the
Type
114
chassis
permits
switching
the

transformer
connections
for
operation
on
either
94.5-137.5
(115
V
