Nouns explanation
Normal mode:
Peak value test mode:
Average mode:
1. Select acquisition mode to observe single
signal
2. Select peak value test mode to observe
envelop of signal to avoid confusion
3. Select average acquisition mode to reduce
random noise in the displayed signal and the
average value frequency shall step in with
multiples of 2
setting average frequency
selection from 2 to 256
oscilloscope collects signal to
reconstruct waveform with equal time interval
under the acquisition
mode
oscilloscope shall find out the maximum
and minimum value of input signal in each
acquisition intervals and to display waveform by
those values
Thus
oscilloscope can acquire
and display narrow pulse or those narrow pulses
will be leaked under the
acquisition
mode and
noise seems louder
under the mode, oscilloscope will
acquire several waveforms to calculate average
value and display waveform finally
thus
reducing random noise
