Connect
a
cable
from
the
SYNC
OUT
connector
to
the
TRIG
input
of
an
oscilloscope.
Connect
a
2W
(or
higher)
50
Ohm
load
to
the
OUT
connector
and
place
the
scope
probe
across
this
load.
Set
the
oscilloscope
to
trigger
externally
with
the
vertical
setting
at
5 Volts/div
and
the
horizontal
setting
at
1
us/div.
Then
follow
the
instructions
below
and
compare
what
is
seen
on
the
oscilloscope
to
what
is
described.
Only
approximate
values
are
needed
to
confirm
operation.
