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.
High Resolution
This mode uses an over-sample technique to average the neighboring points of the
sample waveform. This reduces the random noise on the input signal, generates a
much smoother waveform on the screen and improves the vertical resolution. This is
generally used when the sample rate of the digital converter is greater than the
storage rate of the acquisition memory.
Note: The “Average” and “High Res” modes use different averaging methods. The
former uses “Multi-sample Average” and the latter uses “Single-sample Average”.
