SECTION2
Operation
because the Source Measure
Unit can only store the data
of one sweep. For example, the first
unit
may be used to
set a bias level
and
then trigger the second unit to per-
form a sweep (subordinate sweep). The computer can
then store the sweep data
in
its
own
memory,
and
trigger
the first unit to the next bias level. That unit
will
then trig-
ger the second unit to perform another sweep. The com-
Source
Measure
Unit
#1
+
puter
stores that data
and
again triggers the start of the
next sequence.
This
continues until the test
is
completed.
Multi unit operation
is
covered in paragraph
2.2.5.
