Acquisition Mode


The acquisition mode is used to control how to generate waveform points from
sample points.

Press AcquireAcquisition 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 available range of the number of averages is from 2 to
8192 (only can be the power function of 2) and the default is 2.
