2.5.1 Acquiring Mode
Change the acquiring mode settings and observe the consequent change in waveform display.
Normal Sampling:
Under this mode, oscilloscope takes signal samples at an equal time interval so as to rebuild a waveform. For most
waveforms, it ensures best displaying effect with the use of mode.
Peak Detection
Under this mode, oscilloscope takes both the maximum and minimal signal values within the sampling
interval so as to acquire signal envelopes or narrow pulses that might be lost. Though the use of this mode can
avoid signal aliasing, the noise displayed is relatively large.
Under this mode, oscilloscope can display all pulses with pulse width at least equals to sampling period.
The use of peak detection mode can effectively reduce the appearance of false waveform.
Average
Under this mode, oscilloscope will average the waveform samples taken repeatedly to reduce the random
Setting Description
Normal Normal sampling mode
Sampling Peak detection mode, which is used to detect burrs and to reduce
Peak Detection the possibility of having false waveform;
Average Set average sampling mode and display average times;
High Resolution
Set high resolution display;
Equivalent It requires multiple times of repeated sampling before acquiring
Real time the sampling data needed to form a waveform;
Acquiring all data needed to form a waveform during a single
triggering.

Deep Memory Depth
On Fast sampling is enabled if it is on. By fast sampling, it only takes
Off samples with minimal memory depth, which are needed for
displaying, as a result, it realizes continuous and super high
waveform capture rate.
2～512 Set average times, which steps from the multiple of 2, i.e. 2, 4, 8,
16, 32, 64, 128, 256 and 512. Use "MULTIPURPOSE" knob to
change average times.
