Control
the
4339B
from
an
External
Computer
Most
measurements
can
be
modeled
by
the
following
simple
four
step sequence:
1.
Set
up
the
instrument.
Typically
,
you
begin
the
setup
step by
sending the
*RST command
to set
the instrument
to
its
default
settings
.
Next,
if
you
need
values
dierent
from the
default settings
, change
the
settings
one
by
one
as
required.
2.
Trigger
the
measurement.
The
trigger
may
be
generated
automatically
by steps
taken in
your setup
commands,
or
you
may
send
an
explicit
trigger
command.
To
select the
trigger source
, send
the
:TRIG:SOUR
command
with
the
trigger
source
parameter
. When
you select
BUS as
the trigger
source
,
sending
*TRG
triggers
a
measurement and
retrieves the
measurement data.
3.
Retrieving
the
data.
4.
Turn
OFF
the
test voltage
and end
the measurement.
