Top distance
The distance between the high signal level and the upper reference level - for manual
reference level mode and absolute level definition.
Remote command:
REFLevel<m>:ABSolute:TDIStance on page 1434
Bottom distance
The distance between the lower reference level and the low signal value - for manual
reference level mode and absolute level definition.
Remote command:
REFLevel<m>:ABSolute:BDIStance on page 1435
Upper level
The upper reference level required, for example, to determine a rise - for manual refer-
ence level mode, absolute level definition and user reference level.
Remote command:
REFLevel<m>:ABSolute:ULEVel on page 1435
Lower level
The lower reference level required, for example, to determine a fall - for manual refer-
ence level mode, absolute level definition and user reference level.
Remote command:
REFLevel<m>:ABSolute:LLEVel on page 1436
Histogram averaging
Enables averaging over several histograms to determine the reference levels.
This function is only available in automatic reference level mode.
Remote command:
REFLevel<m>:AUTO[:STATe] on page 1432
Average Count
Defines the number of histograms to calculate the average from.
This function is only available in automatic reference level mode.
Remote command:
REFLevel<m>:AUTO:COUNt on page 1433
8.2.4.3 Advanced tab
Access: "Menu" > "Measure" > "Advanced" tab > "Reference Level" > "Advanced" tab.
This tab allows you to define evaluation tubes for measurements that require high-level
or low-level detection. If the signal value remains within the defined tubes, it is consid-
ered to be high or low.
