Sample Rate
The sample rate of this oscilloscope is up to 5 GSa/s. Note: 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 SCALE or modifying the “Mem Depth”.
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 waveform displayed is rather different from the actual
signal.
2. Waveform Aliasing: 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 fast edge.
