The rejection of noise by setting a hysteresis avoids unwanted trigger events caused
by noise oscillation around the trigger level.
HW hysteresis
Displays the hysteresis that is set by the instrument in automatic hysteresis mode.
Remote command:
TRIGger:NOISe<m>:EFFective? on page 486
Hysteresis mode
Selects how the hysteresis is set.
"Auto"
Automatic mode is the recommended mode. The hysteresis is set by
the instrument to reject the internal noise of the instrument.
"Manual"
The hysteresis is defined directly in absolute or relative values.
Remote command:
TRIGger:NOISe<m>:MODE on page 486
Size mode
Selects whether the hysteresis is defined in absolute or relative values. The setting is
available only in manual hysteresis mode.
Remote command:
TRIGger:NOISe<m>:MODE on page 486
Absolute hysteresis
Defines a range in absolute values around the trigger level. If the signal jitters inside
this range and crosses the trigger level thereby, no trigger event occurs.
Remote command:
TRIGger:NOISe<m>:ABSolute on page 485
Relative hysteresis
Defines a range in divisions around the trigger level in division or as percentage. If the
signal oscillates inside this range and crosses the trigger level thereby, no trigger event
occurs.
