Relative levels
Sets 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 ref level", "Middle ref level", and "Lower ref level".
For example, for "5/50/95" the levels are set to the following values:
●
Lower reference level = 5% of the signal amplitude
●
Middle reference level = 50% of the signal amplitude
●
Upper reference level = 95% of the signal amplitude
Remote command:
REFLevel<m>:RELative:MODE on page 1430
Upper ref level, Middle ref level, Lower ref level
Define the reference levels in percent, if "Relative levels" is set to "User-defined".
Remote command:
REFLevel<m>:RELative:UPPer on page 1436
REFLevel<m>:RELative:MIDDle on page 1437
REFLevel<m>:RELative:LOWer on page 1437
High
Sets the high signal level.
The high signal level is set in manual reference level mode, for absolute level definition
and user signal level selection.
Remote command:
REFLevel<m>:ABSolute:HIGH on page 1433
Low
Sets the low signal level.
The low signal level is set in manual reference level mode, for absolute level definition
and user signal level selection.
Remote command:
REFLevel<m>:ABSolute:LOW on page 1434
Middle
For user signal level selection, the level is the middle level between high and low signal
level. The value is adjusted automatically if you change the high or low signal levels.
Vice versa, if you change the middle level, the high and low signal levels are adjusted.
For user reference level selection, the level is the middle level between upper and
lower reference level. The value is adjusted automatically if you change the upper or
lower reference levels. Vice versa, if you change the middle level, the upper and lower
reference levels are adjusted.
Remote command:
REFLevel<m>:ABSolute:MLEVel on page 1435
