RIGOL 4 To Set the Sample System

DS2000 User’s Guide

4-6

Sample Rate

The sample rate of this oscilloscope is up to 2 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

SCALE or modifying the memory 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 Confusion: when the sample rate is lower than twice the actual

signal frequency (Nyquist Frequency), the frequency of the waveform rebuilt

from the sample data is lower than the actual signal frequency. The most

common aliasing is the jitter on fast edge.
