Product-Specific Commands—Description
Notes When averaging is on and the number of scans is
less than or equal to the Avg Number setting, a
linear average is calculated. After the scan count
exceeds the Avg Number setting, if more burst
has to be acquired.
If Average Mode is Exponential then new results
are averaged in exponentially. In other words,
each succeeding average will be the weighted
sum of the previous average, weighted by (N–
1)/N, and the new measurement, weighted by
1/N, where N is the Average Number setting.
If Average Mode is Last, then average values will
be computed when the acquisition will stop.
The last N bursts will be used to compute the
averages.
State is saved in instrument.
