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. Tip 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.
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. The analog channels real-time sample rate of MSO4000/DS4000 is up to 4 GSa/s. The current sample rate is displayed in the status bar at the upper side of the screen and in the Sa Rate menu (press Acquire Sa Rate).
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. 3. Waveform Leakage: when the sample rate is too low, the waveform rebuilt from the sample data does not reflect the actual signal completely.
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. Note: The digital signal mentioned here refers to the signal generated by comparing the input signal with the threshold level specified by users.

RIGOL Chapter 4 Sample System Setting Peak Detect In this mode, the oscilloscope acquires the maximum and minimum values of the signal within the sample interval to get the envelope of the signal or the narrow pulse that might be lost. In this mode, signal confusion can be prevented but the noise displayed would be larger. In this mode, the oscilloscope can display all the pulses with pulse widths at least as wide as the sample period.
RIGOL Chapter 4 Sample System Setting To Set the Memory Depth The memory depth refers to the number of waveform points that the oscilloscope can store in a single trigger sample and it reflects the storage ability of the acquisition memory. MSO4000/DS4000 provides up to 140 M points memory depth.
RIGOL Chapter 4 Sample System Setting accordingly. Note[1]: When two channels use the same sampler and only one of the two channels is turned on, the system is in the interweave state; when both of the two channels are turned on, the system is in the non-interweave state. For MSO4000/DS4000, CH1 and CH2 use the same sampler; CH3 and CH4 use the same sampler.
Chapter 4 Sample System Setting RIGOL To Turn Anti-aliasing On/Off At slower sweep speed, the sample rate is reduced and the possibility of aliasing can be minimized by using a dedicated display algorithm. Press Acquire and press Anti-Aliasing to turn the anti-aliasing function on or off (the default is off). The displayed waveforms will be more susceptible to aliasing when this function is off.
Chapter 5 Trigger RIGOL Chapter 5 Trigger To generate a trigger, you set a trigger condition according to the requirement; when a waveform in the waveform stream meets this condition, the oscilloscope captures this waveform as well as the neighbouring part immediately and then displays the captured waveforms on the screen. The digital oscilloscope samples waveform data continuously no matter whether it is stably triggered; but only a stable trigger can guarantee stable waveform display.
