ACQUIRE: Press ACQUIRE pushbutton to select the different acquire mode:
Sample, Peak-Detect, and Average. Acquisition is the process of sampling the
analog input signal and converting it into digital format afterward, assembling it into a
waveform record finally.
z Sample: Press F1 to select the “sample” acquisition mode. In sample mode, the
instrument generates a record point by saving the first sample during each
acquisition interval.
z Peak-Detect: The “Peak-Detect” mode stores the minimum and maximum
values (pairs) for each acquisition intervals. Use Peak-Detect acquisition mode
which can detect glitches as narrow as 10ns and the aliasing can be limited
possibly. This mode is effective when the horizontal scale (SEC/DIV) setting
from 500ns/div to 10s/div
z Average: The average mode selects the number of waveform acquisitions that
are averaged to generate the display waveform. The range for the averaging is
from 2 to 256 in powers of 2.
Note: The number select of “average” only effectiveness on the record
lengths of 500.
