Acquisition EN 11 Acquisition Click Utility > Acquire in the lower left corner of the screen to open the acquisition menu. 11.1 Acquisition mode There are four acquisition modes: normal, average, peak and high resolution. ⚫ Normal: Under this mode, the oscilloscope samples the signal at equal intervals to reconstruct the waveform. This represents the analog signal correctly in most cases. However, this method cannot capture the rapid changes of analog signals between two sampling intervals, resulting in confusion and possible loss of narrow pulses in the signal. In order to obtain correct data under the above circumstances, peak ⚫ Average:
Under this mode, oscilloscope takes a number of waveform and then detection acquisition mode should be applied. takes the average, and displays the average waveform, which can be used to reduce random noise. ⚫ Peak detection: Under this mode, the oscilloscope collects the maximum and minimum value of the input signal at each sampling interval and displays the waveform with the sampling data. In this way, the oscilloscope can acquire and display narrow pulses that might be lost. However, the noise effect will be more obvious. ⚫ High resolution:
This mode uses a hypersampling technique that evenly samples adjacent points of the waveform to reduce random noise on the input signal and produce smoother waveforms on the screen. This method is usually used when the sampling rate of the digital converter is higher than the storage rate of the acquisition memory. 11.2 Average times Average times: Copyright © Qingdao Hantek Electronics Co., LTD Tablet1000 User manual 53
