Sample Rate

Sample rate refers to the process that the oscilloscope converts the analog signals to
discrete data at a certain time interval and stores the data in order. Sample rate is the
reciprocal of the time interval.

Sample Rate 1
The sample rate of this oscilloscope is up to 5 GSa/s. Note that the sample rate is
displayed in the status bar at the upper side of the screen and in the Sa Rate menu
and can be changed by adjusting the horizontal time base (s/div) through
HORIZONTAL
The influence on the waveform when the sample rate is too low:
1. Waveform Distortion: when the sample rate is too low, some waveform
details are lost and the sample display of the waveform is rather different from
the actual signal.
2. Waveform Confusion: when the sample rate is lower than twice the actual
signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt by
the sample data is lower than the actual signal frequency. The most common
aliasing is the jitter on a quick edge.
