Data Variable and Analysis Function
Built-in Function
MAVG
Returns the moving average value of 1st expression. The 2nd expression specifies
how many measurement points to use for average.
Syntax MAVG(1st expression,2nd expression)
This operation is defined as follows:
The moving average at measurement index number n is defined as follows:
when n £ r
when r < n £ N-r
when N-r < n
Where,
x
n
: moving average of the 1st expression for measurement index number n.
x
i
: value of the 1st expression for measurement index number i.
r : value of the 2nd expression.
N: number of sweep steps or number of samples.
If there are some invalid values in the 1st expression, the invalid values are ignored
for the calculation.
For each primary sweep, use same definition as for basic sweep measurement and
assume measurement index number 1 for the first step of each primary sweep.
Example To return the moving average value of ''ID'' by using five measurement values:
MAVG(ID,5)
