Chapter V Acquire System
As shown in the figure below, the ACQUIRE on the control area is the function button of
Acquire System.
Figure 5-1 Function Key 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:
