Examples
POWER:SWLOSS:
DISPLAY ENERGYLoss
displays only energy loss measurements
in the results.
POWER:SWLOSS
:DISPLAY ?
might return :POWER:SWLOSS:DISPLAY ALL
indicating that the results displays both energy and power loss measurements.
POWer:SWLoss:GATe:POLarity
This command specifies the switching loss gate polarity.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:SWLoss:GATe:POLarity {FALL|RISe}
POWer:SWLoss:GATe:POLarity?
Arguments
FALL sets falling edge as the switching loss gate polarity.
RISe sets rising edge as the switching loss gate polarity.
Examples
POWER:SWLOSS:GATE:POLARITY FALL sets the gate polarity to Fall.
POWER:SWLOSS:GATE:POLARITY ? might return
:POWER:SWLOSS:GATE:POLARITY RISE indicating that the gate polarity
is set to Rise.
POWer:SWLoss:GATe:TURNON
This command specifies the gate turn on level for switching loss 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:SWLoss:NUMCYCles? <NR3>
Examples
POWER:SWLOSS:NUMCYCLES? might return the number of cycles for
switching loss calculation, if the POWer:TYPe is set to Switching Loss
(
POWer:TYPe:SWITCHingLoss). If the query times out with the Switching
Loss power enabled, it indicates the possibility of incorrect settings and might
return the following:
*ESR?

:power:swloss:numcycles?",410,"Query INTERRUPTED"
POWer:SWLoss:RDSon
This command specifies the user RDSON value for use in switching loss
calculations when the conduction calculation method is RDSON.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Commands Listed in Alphabetical Order
Arguments
<NR3> isafloati
ng point number that specifies the RDSON switching loss
calculation.
Examples
POWER:SWLOSS:RDSON 30 sets the RDSon value to 30.0000.
POWER:SWLOSS:RDSON ? might return :POWER:SWLOSS:RDSon 20.0000E-3
indicating that the RDSon value is set to 20.0000E-3.
POWer:SWLoss:REFLevel:ABSolute:GATEMid
This command specifies the mid voltage reference level used in switching loss
power measurements in volts.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:SWLoss:REFLevel:ABSolute:GATEMid <NR3>
POWer:SWLoss:REFLevel:ABSolute:GATEMid?
Arguments
<NR3> is a floating point number that specifies the mid voltage reference level
in volts.
Examples
POWER:SWLOSS:REFLEVEL:ABSOLUTE:GATEMID 100 sets the absolute gate
mid reference voltage to 100.0000 V.
POWER:SWLOSS:REFLEVEL:ABSOLUTE:GATEMID ? might return
:POWER:SWLOSS:REFLEVEL:ABSOLUTE:GATEMID 50.0000 indicating that
the gate mid reference voltage is set to 50.0000 V.
POWer:SWLoss:REFLevel:ABSolute:LOWCurrent
This command specifies the low current reference level used in switching loss
power measurements in amperes.
Conditions
