set (scope object)
14-79
Mode
For scopes of type 'Target', indicate
how a scope displays the signals. Values
are
'Numerical', 'Redraw' (default),
'Sliding', and 'Rolling'.
For scopes of type
File, specify when a
file allocation table (FAT) entry is
updated. Values are
'Lazy' or
'Commit'. Both modes write the signal
data to the file. With
'Commit' mode,
each file write operation
simultaneously updates the FAT entry
for the file. This mode is slower, but the
file system always knows the actual file
size. With
'Lazy' mode, the FAT entry
is updated only when the file is closed
and not during each file write
operation. This mode is faster, but if the
system crashes before the file is closed,
the file system might not know the
actual file size (the file contents,
however, will be intact).
For scopes of type
Host, this parameter
has no effect.
Yes
NumPrePostSamples
For scopes of type 'Host' or 'Target',
this parameter is the number of
samples collected before or after a
trigger event. The default value is 0.
Entering a negative value collects
samples before the trigger event.
Entering a positive value collects
samples after the trigger event. If you
set
TriggerMode to 'FreeRun', this
property has no effect on data
acquisition.
