User defined: Enter "Upper ref level", "Middle ref level", and "Lower ref level".
For example, for "5/50/95":
●
lower reference level = 5% of high signal level
●
middle reference level = 50% of high signal level
●
upper reference level = 95% of high signal level
SCPI command:
REFLevel<m>:RELative:MODE on page 529
Upper ref level, Middle ref level, Lower ref level
Define any reference levels in percent, if "Relative levels" is set to "User-defined".
