Page 102: Sample Mode
RIGOL Chapter 4 Sample System Setting Sample Mode This oscilloscope only supports real-time sampling. In this mode, the oscilloscope samples and displays waveforms within a trigger event. When the sample is stopped, the oscilloscope will hold the last display. At this point, you can still use the vertical control and horizontal control to pan and zoom the waveform.
Page 103: Sample Rate
Chapter 4 Sample System Setting RIGOL Sample Rate Sample refers to the process that the oscilloscope converts analog signals to digital signals at a certain time interval and stores the data in order. The sample rate is the reciprocal of the time interval.
Page 104 RIGOL Chapter 4 Sample System Setting 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.
Page 105: La Sample Rate
Chapter 4 Sample System Setting RIGOL LA Sample Rate The LA sampling refers to the process that the oscilloscope samples the compared digital signals at a certain time interval. The LA sample rate is the reciprocal of the time interval. For example, the oscilloscope with 1 GHz LA sample rate samples digital signals every 1 ns.
