Chapter 4 To Set the Sample System
Acquisition Mode
The acquisition mode is used to control how to generate waveform points from
sample points.
Press Acquire Acquisition and use
to select the desired acquisition mode
(the default is "Normal"), then press down the knob to select this mode. You can also
press Acquisition continuously to switch the acquisition mode.
Normal
In this mode, the oscilloscope samples the signal at equal time interval to rebuild the
waveform. For most of the waveforms, the best display effect can be obtained using
this mode.
Average
In this mode, the oscilloscope averages the waveforms from multiple samples to
reduce the random noise of the input signal and improve the vertical resolution. The
greater the number of averages is, the lower the noise will be and the higher the
vertical resolution will be but the slower the response of the displayed waveform to
the waveform changes will be.
When "Average" mode is selected, press Averages and use
to set the desired
number of averages. The numbers of averages available include 2, 4, 8, 16, 32, 64,
128, 256, 512, 1024, 2048, 4096 and 8192. The default is 2.
