The maximum number of times data is measured (using the
smeas
X
,
sintg
X
, or
savg
X
command)
is determined by the
num_points
argument in the
asweep
X
command. A one-dimensional result
array with the same number of data elements as the selected value of the
num_points
parameter
must be defined in the test program.
When multiple calls to the
asweep
X
command are executed in the same test sequence, the
smeas
X
,
sintg
X
, or
savg
X
arrays are loaded sequentially. This appends the measurements from the second
asweep
X
command to the previous results. If the arrays are not dimensioned correctly, access
violations occur. The measurement table remains intact until the
devint
or
clrscn
command is
executed.
Defining new test sequences using the
smeas
X
,
sintg
X
, or
savg
X
command appends the command
to the active measure list. Previous measures are still defined and will be used. The
clrscn
command is used to eliminate previous buffers for the second sweep. Using the
smeas
X
,
sintg
X
,
and
savg
X
commands after calling the
clrscn
command causes the appropriate new measures to
be defined and used.
