Level mode
Defines if the reference level is set in absolute or relative values.
Remote command:
REFLevel<rl>:LMODe on page 627
Absolute Level mode
In the absolute mode, the reference values are set as voltages, in absolute values.
Upper level, Middle level, Lower level ← Absolute Level mode
Sets the low, middle and upper reference signal levels.
Remote command:
REFLevel<rl>:ABSolute:LLEVel on page 628
REFLevel<rl>:ABSolute:MLEVel on page 628
REFLevel<rl>:ABSolute:ULEVel on page 628
Relative Level mode
In the relative mode, the reference values are set as percentages of the signal ampli-
tude.
Relative levels ← Relative Level mode
Selects the lower, middle and upper reference levels, defined as percentages of the
signal amplitude.
Available relative levels:
●
5/50/95
●
10/50/90
●
20/50/80
●
User defined: Enter "Upper level", "Middle level", and "Lower level".
For example, for "5/50/95" the levels are set to the following values:
●
Lower level = 5% of the signal amplitude
●
Middle level = 50% of the signal amplitude
●
Upper level = 95% of the signal amplitude
Remote command:
REFLevel<rl>:RELative:MODE on page 630
Upper level, Middle level,Lower level ← Relative Level mode
Define the reference levels in percent, if "Level mode" is set to "User-defined".
Remote command:
REFLevel<rl>:RELative:LOWer on page 629
REFLevel<rl>:RELative:MIDDle on page 629
REFLevel<rl>:RELative:UPPer on page 630
Hysteresis
Defines a hysteresis for the middle reference level. A rise or fall from the middle refer-
ence value that does not exceed the hysteresis is rejected as noise.
Remote command:
REFLevel<rl>:ABSolute:HYSTeresis on page 627
REFLevel<rl>:RELative:HYSTeresis on page 629
