The waveform displayed on the screen or
the waveform data saved in "Saving
Noise Data and Waveform Data" (p. 145)
always uses the Peak-Peak compressed
waveform data sampled at 500 kS/s.
Therefore, even if the sampling speed is
set low, it will be an accurate waveform
with peak information of the waveform
before compression.
The data of saved waveform data is
linked to the same number of points for
noise analysis, and for each point, the
maximum value and minimum value in
the figure on the right are both saved.

• To shorten the time it takes to renew the waveform display, decrease the number of points
for noise analysis. The quickest display renewal is 1000 points. See "4.6.2 Setting the
Sampling Frequency and Points" (p. 85)
• Changing the settings for waveform display and noise analysis do not affect the electric
power or the sampling for harmonic measurement.
