To Specify the Acquisition Mode 
 
The acquisition mode is used to control how to generate waveform points from 
sample points. 
 
Press Acquire  Acquisition and turn the multi-function knob   to select the 
desired acquisition mode; then, press the knob. The acquisiton modes available 
include normal, average, peak detect and high-resolution. The default is normal. You 
can also press Acquisition continuously to switch the current 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.  
 
When “Average” mode is selected, press Averages and turn the multi-function knob 
 to increase or reduce the 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.  
 
More averages can lower the noise and increase the vertical resolution; but, it will 
slow the response of the displayed waveform to the waveform changes.
