MEASUrement:
IMMed:REFLevel:METHod
This command specifies or queries the reference level units used for measurement
calculations. This command is equivalent to selecting Reference Levels from
the Measure m
enu and then choosing the desired reference level from the Units
group box.

Syntax
MEASUrement:IMMed:REFLeve l:METHod {ABSolute|PERCen t}
MEASUrement:IMMed:REFLeve l:METHod?
Arguments
ABSolute specifies that the reference levels are set explicitly using
the
MEASUrement:IMMed:REFLevel:A BSolute 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:IMMed:REFLeve l:PERCentcommands.
Examples
MEASUREMENT:IMMED:REFLEVE L:METHOD ABSOLUTE specifies that explicit
user-defined values are used for the reference levels.
MEASUREMENT:IMMED:REFLEVE L:METHOD? might return
:MEASUREMENT:IMMED:REFLEV EL:METHOD PERCENT, indicating
that the reference level units used are calculated as a percent relative to HIGH
and LOW.
MEASUrement:IMMed:REFLevel:PERCent:HIGH
This command sets or queries the percentage (where 100% is equal to HIGH) used
to calculate the high reference level when MEASUrement:IMMed:REFLevel:
METHod is set to Percent. Note that this command affects the results of rise
and fall measurements.
NOTE. This command affects the results of period, frequency, delay, and all
cyclic measurements.
