MEASUrement:MEAS<x>:REFLevel:METHod
Description
This command specifies or queries the reference level units used for
measurement calculations. This command is equivalent to selecting
Reference Levels from the Measure menu and then choosing the de-
sired reference level from the Units group box. Measurements are spe-
cified by x, which ranges from 1 through 8.

Syntax 1
MEASUrement:MEAS<x>:REFLevel:METHod {ABSo-
lute|PERCent}
Syntax 2
MEASUrement:MEAS<x>:REFLevel:METHod?
Arguments
H ABSolute
This specifies that the reference levels are set explicitly using the
MEASUrement:MEAS<x>: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.
H PERCent
This specifies that the reference levels are calculated as a percent rela-
tive to HIGH and LOW. The percentages are defined using the MEA-
SUrement:MEAS<x>:REFLevel:PERCent commands.
Example 1
MEASUREMENT:MEAS1:REFLEVEL:METHOD ABSOLUTE
This command specifies that explicit user--defined values are used for
the reference levels.
Example 2
MEASUREMENT:MEAS1:REFLEVEL:METHOD?
This query might return
:MEASUREMENT:MEAS1:REFLEVEL:METHOD PERCENT
indicating that the reference level units used are calculated as a percent
relative to HIGH and LOW.
