For selecting whether the levels should be set in absolute or
percentage of the peak–to–peak signal value.
hysteresis
To set the hysteresis division. Hysteresis essentially enables the
user to set a voltage band, which a waveform peak–trough pair
must exceed in order not be considered either noise or a “bump”.
This threshold crossing is recognized when an acquisition point in
the waveform passes through the threshold level by 1/2 the
hysteresis-division setting.
