MEASUrement:
REFLevel:METHod
Specifies or returns the reference level units used for measurement calculations.
NOTE. this command affects the associated reference level parameter
for all MEAS
urements:IMMed and the eight periodic measurements (4 in
MDO3000). To change the parameter for individual measurements, use the
MEASUrement:MEAS<x>:REFLevel commands.

Syntax
MEASUrement:REFLevel:METHod {ABSolute|PERCent}
MEASUrement:REFLevel:METHod?
Arguments
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 example, when
designing to published interface
specifications, such as RS-232-C).
PERCent specifies that the reference levels ar
e calculated as a percent
relative to HIGH and LOW. The percentages are defined using the
MEASUrement:REFLevel:PERCent commands.
Examples
MEASUREMENT:REFLEVEL:METHODABSOLUTE specifies that explicit user-defined
values are used for the reference levels.
MEASUREMENT:REFLEVEL:METHOD? might return
:MEASUREMENT:REFLEVEL:METHOD PERCENT indicating that the reference
level units used are calculated as a percent relative to HIGH and LOW.
MEASUrement:REFLevel:PERCent:HIGH
This command specifies the percent (where 100% is equal to HIGH) used to
calculate the high reference level when MEASUrement:REFLevel:METHod is set
to Percent. This command affects the results of rise and fall measurements.
NOTE. This command affects the associated reference level parameter for all
MEASurements:IMMed and the four periodic measurements.
