SmthNum
SmthNum defines the number of measurement points used for the smoothing
function of oscilloscope. SmthNum must be less than SmplNum.
SmthStat
SmthStat sets the smoothing function ON or OFF of the oscilloscope.
The smoothing function averages the time-series data to reduce variations caused by
high-frequency components. Set the value in order to display the pulse waveform on
the oscilloscope screen. A too large number of smoothing points loses waveform
edges, which disturbs accurate results.
Figure 5-10 Smoothing Function
AvgNum
AvgNum specifies the measurement averaging number set to the oscilloscope. The
scope measures pulse waveform the specified number of times and displays the
averaged pulse waveform. A large number reduces random noise and increases
sharpness of waveform.
