2–235
ABSolute specifies that the reference levels are set explicitly using the
MEASUrement:REFLevel:ABSolute commands. This method is useful when
precise values are required. For instance, when designing to published interface
specifications such as RS-232-C.
PERCent specifies that the reference levels are calculated as a percent relative to
HIGH and LOW. The percentages are defined using the MEASUrement:REFLe-
vel:PERCent commands.
MEASUREMENT:REFLEVEL:METHOD ABSolute
specifies that explicit user-defined values are used for the reference levels.
MEASUREMENT:REFLEVEL:METHOD?
returns either ABSolute or PERCENT, indicating the reference levels used.
MEASUrement:REFLevel:PERCent:HIGH
Sets or queries the percent, where 100% is equal to HIGH, that is used to
calculate the high reference level when MEASUrement:REFLevel:METHod is
set to PERCent. This command is equivalent to setting the Reference Levels in
the Measure menu.
