Description:
Averaging overview:
Averaging is turned on with the AVER ON command.
AVER:IRES turns fast averaging on and off.
AVER:IRES:RATE specifies the fast averaging update rate.
AVER:TYPE specifies the average type: RMS (power), complex (time), or max (peak hold).
AVER:TCON specifies termination control types which are normal, exponential, or repeat.
For normal averaging (AVER:TCON NORM), AVER:COUN specifies the number of
–
measurement results that are averaged together. When the specified number of
measurements have been taken and averaged together, the analyzer quits taking data and
sets the NPO flag (No Pending Operations) to 1.
If repeat averaging is on (AVER:TCON REP), the averaging process restarts immediately
–
after the current average is completed.
For exponential averaging (AVER:TCON EXP), AVER:COUN specifies a weighting factor
–
which determines how the results of previous (averaged) measurement data (AVG
combined with the current measurement data (X
as described by:
where n is the weighting factor specified by AVER:COUN. Note that for small values of
n, the new data is a significant part of the average; for large values of n, new data has
much less weight in the calculated average.
Note
For exponential averaging, the averaging process does not stop after n
measurements. The NPO flag is set to 1 after n measurements.
