Trigger Descriptions:
All of the available
input
triggers are described as fol-
lows:
CONTINUOUS
IN
De Operation: As long as the MANUAL TRIGGER light
is
on
and
not
blinking, a trigger is
not
needed. A continu-
ous series of SDM cycles commence
when
the the
unit
is
placed
in
OPERATE. When the MANUAL TRIGGER
light is blinking, a trigger is required to start the continu-
ous
source-delay-measure process.
Sweep Operation: A single trigger causes the sweep to
start
and
continue until
it
is complete.
In
other words, a
single trigger causes
all SDM cycles
in
the sweep to be
processed.

De Operation: Each trigger processes a single SDM cycle.
That is, each trigger causes a source, delay,
and
measure-
ment to occur.
Sweep Operation: For each SDM cycle of the sweep, a
trigger causes a source, delay,
and
measurement (which
is displayed) to occur. After the last measurement of the
sweep is made, a following trigger causes the
unit
to re-
turn
to the bias level.
De Operation:
An
initial trigger sets the level of the
source. Each subsequent trigger causes a delay
and
meas-
urement to occur,
and
re-applies the source level
of
the
next SDM cycle.
Sweep Operation:
An
initial trigger starts the sweep
process
by
setting the
unit
to the first source level of the
sweep. A measurement is
not
made
at
this time. For each
SDM cycle of the sweep, a trigger causes a delay
and
measurement to occur,
and
sets the
unit
to the source
level of the next SDM cycle. After the last measurement
(which is displayed)
of
the sweep is made, a following
trigger causes the
unit
to return to the bias level.

De Operation: Each SDM cycle is processed
by
two
trig-
gers. The first trigger sets the source level
and
the the sec-
ond
trigger causes a delay
and
measure to occur.
Sweep Operation: Two triggers process each SDM cycle
of the sweep. The first trigger sets the source level
and
the
second trigger causes a delay
and
measurement (which is
displayed) to occur. A trigger following the last measure-
ment
in
the sweep causes the
unit
to
return to the bias
level.
De Operation:
An
initial trigger sets the source level
and
causes a delay to occur. Each subsequent trigger causes a
measurement to occur,
and
then processes the source
and
delay phases of the next SDM cycle.
Sweep Operation:
An
initial trigger starts the sweep
process
by
setting the
unit
to the first source level
and
causing a delay to occur. A measurement is
not
made
at
this time. For each SDM cycle of the sweep, a trigger
causes a measurement
to
be made. Also,
it
sets the source
level of the next SDM cycle
and
causes a delay to occur.
After the last measurement (which is displayed)
in
the
sweep is made, a following trigger returns the
unit
to the
bias level.
De Operation: Each SDM cycle is processed
by
two trig-
gers. The first trigger sets the source level
and
causes a
delay to occur. The second trigger causes a measurement
to occur.
Sweep Operation: Two triggers
are
required to process
each SDM cycle of the sweep. The first trigger sets the
source level
and
causes a delay to occur. The second trig-
ger
qmses
a measurement (which is displayed) to occur.
A trigger following the last measurement
in
the sweep
will
return
the
unit
to the bias level.
De Operation:
An
initial trigger sets the level of the
source. Each SDM cycle of the sweep is then processed
by
two
triggers. The first trigger causes a delay to occur. The
