Notice:
(1) Please select real-time sampling mode when observing single signal.
(2) Please select equivalent sampling mode when observing high frequency periodic signal.
(3) Please select peak detection mode when hoping to observe the signal envelope for any
modulation signal. Please select average sampling mode when hoping to reduce the
random noise in displayed signals, and set the average number to 2, 4, 8, 16, 32, 64,128,
256, 512.
Explanation of nouns
Sampling mode:
Real-time sampling and equivalent sampling
Real-time sampling mode
: Data sampling at the real-time sampling rate of the system.
This is used to observe any waveform within the sampling rate of the system.
Equivalent sampling mode
: Data sampling at higher than maximum sampling rate of the
system. This is used to observe any periodical waveform at beyond the maximum sampling
rate.
Peak value mode:
DSO finds the maximum and minimum value of input signal in each
sampling interval and uses these values to display waveform. In this mode, DSO can
acquire and display narrow pulses, otherwise these pulses may be lost in sampling mode.
The noise will be stronger in this mode.
High resolution mode:
The DSO averages the proximal point of acquired waveform to
reduce random noise of input signal and display a smoother wave on the screen.
Average mode:
The DSO acquires some waveforms and calculate their average values,
and then display the final waveform.
