Chapter V  Acquire System 
As shown in the figure below, the ACQUIRE on the control area is the function button of 
Acquire System.

Press ACQUIRE button to enter data acquisition setting menu, set the data acquisition 
mode through menu control button. 
Table 5-1 Acquire Function Menu 
The DSO acquires data and reconstruct the waveform in the same time interval. 
Set to peak value acquisition mode. The DSO finds the maximum and minimum 
value of input signal in each acquiring interval and uses these values to display 
waveform. 
The DSO averages the proximal point of acquired waveform to reduce random 
noise of input signal and display a smoother wave on the screen. 
The DSO acquires some waveforms and calculate their average values, and 
then display the final waveform. 
Set average number by using the multipurpose knob, the average number is set 
to 2, 4, 8, 16, 32, 64,128, 256, 512 
Set to Real-time sampling.   
Set to Equivalent sampling.   
Acquire data in a way of high screen refresh rate to better reflect the dynamic 
effect of waveform. 
By  changing  the  acquisition  setting  of  the  DSO,  user  can  observe  the  wave  change. 
Assuming that the noise in signal is strong, non-average acquisition method and average 
acquisition of 8 numbers are shown in the figure below:
