Attribute Summary:
Description:
The types of averaging available vary according to the instrument mode.
FFT analysis instrument mode (INST:SEL FFT):
To select rms (power) averaging, send AVER:TYPE RMS. The analyzer averages N time records
where N is the number of averages you specify with the AVER:COUN command.
To select exponential rms (power) averaging, send AVER:TYPE RMS;TCON EXP. The number of
averages specified with AVER:COUN determines the weighting of old versus new data.
To select time averaging, send AVER:TYPE TIME. The analyzer averages complex values
point-by-point in the frequency domain. The averaged frequency domain spectra is transformed
(inverse FFT) to give averaged time data. The input signal must be periodic and a trigger signal
from the analyzer's source or from an external signal must be provided.
To select exponential time averaging, send AVER:TYPE TIME;TCON EXP. The number of
averages specified with AVER:COUN determines the weighting of old versus new data.
Send AVER:TYPE MAX to select the peak hold function. The analyzer takes data continuously
and mathematically compares each data point along the measured frequency span with the previous
peak values. Only the largest value of each point is saved. The results are not mathematically
averaged.
