If this function is used to abort a sweep, when it is executed, the SMU exits its trigger model
immediately and returns to the idle state of the trigger model.
Example
smua.abort()
Terminates all overlapped operations on SMU channel A.
Also see
smuX.buffer.getstats()
This function returns a specified reading buffer's statistics.

Usage

.buffer.getstats(

statistics
The statistical data about the data in the reading buffer

Source-measure unit (SMU) channel (for example,
smua.buffer.getstats()
specifies SMU channel A)
bufferVar
The reading buffer to process
Details
This function returns a table with statistical data about the data that is placed in the buffer.
The SMU automatically updates reading buffer statistics as data is added to the reading buffer. When
the reading buffer is configured to wrap around and overwrite older data with new data, the buffer
statistics include the data that was overwritten.
The table returned from this function is a snapshot. Although the SMU continues to update the
statistics, the table returned is not updated. To get fresh statistics, call this function again.
The
statistics
parameter has the attributes described in the following table.
Attribute
When returned
Description
n
Always
The number of data points on which the statistics are based
mean
When
n
> 0
The average of all readings added to the buffer
stddev
When
n
> 1
The standard deviation of all readings (samples) added to the buffer
min
When
n
> 0
A table containing data about the minimum reading value added to the
buffer
max
When
n
> 0
A table containing data about the maximum reading value added to the
buffer
If
n
equals zero (0), all other attributes are
nil
. If
n
equals 1, the
stddev
attribute is
nil
because
the standard deviation of a sample size of 1 is undefined.
The
min
and
max
entries each have the attributes defined in the following table.
