Upper level
The upper reference level, required e.g. to determine a rise - for manual reference level
mode, absolute level definition and user reference level.
SCPI command:

Lower level
The lower reference level, required e.g. to determine a fall - for manual reference level
mode, absolute level definition and user reference level.
SCPI command:

Histogram averaging
Enables averaging over several histograms to determine the reference levels.
This function is only available in automatic reference level mode.
SCPI command:
REFLevel<m>:AUTO[:STATe] on page 531
Average Count
Defines the number of histograms to calculate the average from.
This function is only available in automatic reference level mode.
SCPI command:
REFLevel<m>:AUTO:COUNt on page 532
Hysteresis Tab
This tab allows you to define a hysteresis for measurements that determine zero-cross-
ings.
