High Resolution Mode

In Normal mode at slower sweep speeds, extra samples are
decimated (in other words, some are thrown away). This mode
yields the best display for most waveforms.
In Peak Detect mode at slower sweep speeds, minimum and
maximum samples are kept in order to capture infrequent and
narrow events (at the expense of exaggerating any noise). This
mode displays all pulses that are at least as wide as the sample
period (see Table 16).

In High Resolution mode, at slower sweep speeds extra samples
are averaged in order to reduce random noise, produce a
smoother trace on the screen, and effectively increase vertical
resolution.
High Resolution mode averages sequential sample points within
the same acquisition together. An extra bit of vertical resolution
is produced for every factor of 4 averages. The number of extra
bits of vertical resolution is dependent on the time per division
setting (sweep speed) of the scope.
The slower the sweep speed, the greater the number of samples
that are averaged together for each display point.
