Syntax
POWer:REFLevel:PERCent:HIGH <NR3>; Ranges={D,0.0,1 00.0}
POWer:REFLevel:PERCent:HIGH?
Arguments
<NR3> is a floating point number that specifies the high value in percent.
Examples
POWER:REFLEVEL:PERCENT:HIGH 95 sets the high reference level to 95% of
the signal amplitude.
POWER:REFLEVEL:PERCENT:HIGH? might return
:POWER:REFLEVEL:PERCENT:HIGH 90 indicating that the percentage high
reference level is set to 90% of the signal amplitude.
POWer:REFLevel:PERCent:LOW
This command specifies the low reference percent 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:PERCent:LOW <NR3>; R anges={D,0.0,100.0}
POWer:REFLevel:PERCent:LOW?
Arguments
<NR3> is a floating point number that specifies the low value in percentage.
Examples
POWER:REFLEVEL:PERCENT:LOW 15 sets the low reference level to 15% of the
signal amplitude.
POWER:REFLEVEL:PERCENT:LOW? might return
:POWER:REFLEVEL:PERCENT:LOW 10 indicating that the percentage low
reference level is set to 90% of the signal amplitude.

POWer:REFLev
el:PERCent:MID<x>
This command specifies one of 3 mid reference percentage levels to be used for
power measurements. MID1 is used on the user’s voltage waveform. MID2 is
used on the us
er’s current waveform. MID3 is used on the user’s gate waveform.
(MID3 is specific to power applications.)
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:MID<x> <NR3>; Ranges={D,0.0 ,100.0}
POWer:REFLevel:PERCent:MID<x>?
Arguments
<NR3> is a floating point number that specifies the mid value in percentage.
Examples
POWER:REFLEVEL:PERCENT:MID1 25 sets the mid reference voltage to 25%.
POWER:REFLEVEL:PERCENT:MID1? might return
POWER:REFLEVEL:PERCENT:MID1 50.0000 indicating that the mid reference
voltage level is set to 50%.
POWer:RIPPle (No Query Form)
This command performs a vertical autoset for ripple measurements or sets the
vertical offset to 0.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.
Group
Power
Syntax
POWer:RIPPle {VERTAUTO set|VERTDEFault}
Arguments
VERTAUTOset automatically scales the source waveform to optimize ripple
measurements.
VERTDEFault sets the vertical offset of the source waveform to 0 volts (for
voltage source) or 0 amperes (for cur
rent source).
