High Resolution Acquisition Mode
In High Resolution mode, at slower time/div settings when decimation
would normally occur, 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. 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 oscilloscope's time per division setting (sweep speed) and the
displayed sample rate.
The slower the time/div setting, the greater the number of samples that
are averaged together for each display point.
High Resolution mode can be used on both single- shot and repetitive
signals and it does not slow waveform update because the computation is
done in the MegaZoom custom ASIC. High Resolution mode limits the
oscilloscope's real-time bandwidth because it effectively acts like a
low- pass filter.
Acquiring to Segmented Memory
You can purchase the oscilloscope with the segmented memory option
factory- installed (Option SGM) or you can install a license to enable it
(order model number DSOX2SGM "Segmented Memory").
