Commands Listed in Alphabetical Order
Arguments Auto selects the best method for each data set.
HIStogram sets the high and low waveform levels statistically using a histogram
algorithm.
MINMax uses the highest and lowest values of the waveform record. This selection
is best for examining waveforms with no large, flat portions of a common value,
such as sine waves and triangle waves.
Examples MEASUREMENT:METHOD? might return :MEASUREMENT:METHOD MINMAX
indicating that the reference levels are set to MIN and MAX.
MEASUrement:REFLevel? (Query Only)
Returns the current reference level parameters.

Syntax MEASUrement:REFLevel?

Examples MEASUREMENT:REFLEVEL? might return these reference
level settings :MEASUREMENT:REFLEVEL:METHOD
PERCENT;ABSOLUTE:HIGH 0.0000;LOW 0.0000;MID1 0.0000 ;MID2
0.0000;:MEASUREMENT:REFLEVEL:PERCENT:HIGH 90.0000;LOW
10.0000;MID1 50.0000 ;MID2 50.0000
MEASUrement:REFLevel:ABSolute:HIGH
Sets or returns the high reference level, and is the upper reference level when
MEASUrement:REFLevel:METHod is set to Absolute. 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.
