4.3 Acquiring Waveforms Using the Utility Functions
106
This applies to the Memory function only.
The specified number of waveform samples is acquired and average values are
calculated to obtain the data to be displayed.
Use this function to suppress superimposed noise and instabilities from cyclic
waveforms. Increasing the number of waveform samples specified for averaging
generally enhances noise suppression.

Operating Key Procedure
1
Enable the Averaging function
CURSOR Move the cursor to the [ Averaging ] item.
F1 to F8 Enable or disable the function.
2
With Averaging enabled [On]
CURSOR Move the cursor to the [ Number ] item.
F1 to F8 Set the number of waveform samples to be aver-
aged.
With Exponential Averaging enabled [On (Exponent)]
CURSOR Move the cursor to the [ Number ] item.
F1 to F8 Set the number of waveform samples to be aver-
aged.
CURSOR
Move the cursor to the [ Attenuation ] item.
F1 to F8
Set the weighting ratio (attenuation constant).
Once measurement starts, the number of waveform samples speci-
fied to be averaged and the number of samples currently acquired
are displayed.
Off
No averaging is performed.(default set-
ting)
On
(Simple Averaging): Averages the speci-
fied number of waveform samples
On
(Exponent)
(Exponential Averaging): Applies the
specified weighting to the most recent
data and averages with less weighting
applied (exponentially) to earlier data.
