Query Response
CALCulate:SDEViation?
[<count>[,<offset>
[,<step size>]]]
This query calculates and returns the standard deviation for a
set of data. The formula used for standard deviation is:
s = sqrt (S (datai – average)2/(n–1)
(n = amount of data summed)
If no valid data values were found “No Data” will be returned.
The optional parameters are for calculating selected values in
the memory buffer.
The optional <count> parameter specifies the number of
datapoints to calculate. If no <count> is specified, then the
number measurements last taken will be the default.
The optional <offset> parameter determines at which point in
memory values will start to be calculated.
The optional <step_size> parameter determines the number of
measurements to skip before taking a value to be used.
NOTE: In order to specify a <step_size>, you must enter the
<count> and the <offset> information.
