RIGOL Chapter 4 To Set the Sample System

4-4 MSO2000A/DS2000A User’s Guide

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

of the signal that might be lost. In this mode, signal confusion can be prevented, but

the noise displayed would be larger.

High Resolution

This mode uses a kind of ultra-sample technique to average the neighboring points

of the sample waveform to reduce the random noise on the input signal and generate

much smoother waveforms on the screen. This is generally used when the sample

rate of the digital converter is higher than the storage rate of the acquisition memory.

Note: “Average” and “High Res” modes use different averaging methods. The

former uses “Multi-sample Average” and the latter uses “Single Sample Average”.
