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
detection acquisition mode should be applied.
⚫ Average: Under this mode, oscilloscope takes a number of waveform and then
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.
