Examples
POWER:REFLEVE
L:ABSOLUTE:HIGH 2
sets the absolute high value to 2.000.
POWER:REFLEVEL:ABSOLUTE:HIGH? might return
POWER:REFLEV
EL:ABSOLUTE:HIGH 2
indicating that the absolute high
valueissetto2V.
POWer:REFLevel:ABSolute:LOW
This comman
d specifies the low reference level to be used for power
measurements.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:REFLevel:ABSolute:LOW <NR3>; Ranges={D,-1e6, +1E6}
POWer:REFLevel:ABSolute:LOW?
Arguments
<NR3> is a floating point numb
er that specifies the absolute low value in volts.
Default value is 0.0E+0.
Examples
POWER:REFLEVEL:ABSOLUTE:LOW 1.0 sets the absolute high value to 1.0000.
POWER:REFLEVEL:ABSOLUTE:LOW? might return
POWER:REFLEVEL:ABSOLUTE:LOW 1.0000 indicating that the absolute low
valueissetto1V.
POWer:REFLevel:ABSolute:MID<x>
This command specifies the mid reference level to be used for power
measurements. MID1 is used on the user’s voltage waveform. MID2 is used on
the user’s current waveform. MID3 is used on the user’s gate waveform. (MID3
is specific to the power application.)
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:REFLeve
l:ABSolute:MID<x> <NR3>; Ranges={D,-1 e6,+1E6}
POWer:REFLevel:ABSolute:MID<x>?
Arguments
<NR3> is a floating point number that specifies the absolute mid reference value.
Examples
POWER:REFLEVEL:ABSOLUTE:MID1 1 sets the mid reference voltage to 1V.
POWER:REFLEVEL:ABSOLUTE:MID1? might return
POWER:REFLEVEL:ABSOLUTE:MID1 0.0E+0 indicating that the absolute
reference voltage level is set to 0.0E+0 V.
POWer:REFLevel:HYSTeresis
This command specifies the reference level hysteresis value to be used for power
measurements.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:REFLevel:HYSTeresis <NR3>
POWer:REFLevel:HYSTeresis?
Arguments
<NR3> is a floating point number that specifies the hysteresis value.
Examples
POWER:REFLEVEL:HYSTERESIS 30 sets the hysteresis value to 30.
POWER:REFLEVEL:HYSTERESIS? might return
POWER:REFLEVEL:HYSTERESIS 10 indicating that the hysteresis value is
set to 10.
POWer:REFLevel:METHod
This command specifies the method used to calculate the 0% and 100% reference
level to be use
d for power measurements.
Conditions
This command requires a DPO4PWR application module for 4000 series model
s,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:REFLevel:METHod {ABS
olute|PERCent}
POWer: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.
PERCent specifies that the reference levels are calculated as a percent
of the signal amplitude. The percentages are defined using the
MEASUrement:REFLevel:PERCent commands.
Examples
POWER:REFLEVEL:METHOD ABSOLUTE specifies that explicit user-defined values
are used for the reference levels.
POWER:REFLEVEL:METHOD? might return P OWER:REFLEVEL:METHOD
PERCENT
indicating that the reference level units used are calculated as a percent
relative to HIGH and LOW.
POWer:REFLevel:PERCent (No Query Form)
This command sets the reference levels to be used for power measurements to
the default percentage values.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:REFLevel:PERCent <SETTODEFaults>
Arguments
SETTODEFaults sets the reference levels to their default perce
ntage values.
POWer:REFLevel:PERCent:HIGH
This command specifies the top reference percent level to be used for power
measurements.
