Syntax
MEASUrement:CH<x>:REFLevels:ABSolute:TYPE {SAME|UNIQue}
MEASUrement:CH<x>:REFLevels:ABSolute:TYPE?
Arguments
SAME
speci fi es that the absolute reference levels for the speci fi ed measurement
channel are the same.
UNIQue
speci fi es that the absolute reference levels for the speci fi ed measurement
channel are not the same.
Examples
MEASUREMENT:CH2:REFLEVELS:ABSOLUTE:TYPE SAME
set the reference
levels to be the same.
MEASUREMENT:CH2:REFLEVELS:ABSOLUTE:TYPE?
might return
:MEASUREMENT:CH2:REFLEVELS:ABSOLUTE:TYPE SAME
indicating that the
reference levels for absolute measurements are the same.
MEASUrement:CH<x>:REFLevels:BASETop
This command sets or queries the method used to calculate the TOP and BASE,
used to calculate reference levels for the measurement. The channel number
is speci
fi ed by x.
Group
Measurement
Syntax
MEASUrement:CH<x>:REFLevels:BASETop
{AUTO|MINMax|MEANhistogram| MODEhistogram|EYEhistogram}
MEASUrement:CH<x>:REFLevels:BASETop?
Arguments
AUTO
automatically chooses a reference level method.
MINMax
speci fi es that reference levels are relative to the measurement MIN and
MAX.
MEANhistogram
speci fi es that reference levels are relative to the histogram mean
BASE and TOP.
MODEhistogram
speci fi es that reference levels are relative to the histogram mode
BASE and TOP.
EYEhistogram
speci fi es that reverence levels are relative to the eye histogram
BASE and TOP.
Examples
MEASUREMENT:CH2:REFLEVELS:BASETOP MINMAX
speci fi es that reference
levels are relative to the measurement MIN and MAX.
