SWLoss:LOG:CONDUCTION? Return the Conduction Loss for a switching
loss measurement
SWLoss:LOG:INDEX Set or query which measurement to return
for a SWLoss:LOG command
SWLoss:LOG:TOTAL? Return the Total Loss for a switching loss
measurement
SWLoss:LOG:TURNOFF? Return the Turn-Off Loss for a switching loss
measurement

measurement
SWLoss:SAVE Saves the Switching Loss Measurements
SWLoss:SOURCES Set or query the input sources for Switching
Loss M easurements
SWLoss:STOPAfter Set or query the number of acquisitions used
for Switching Loss Measurements
SWLoss:TOFFEND Set or query a level on the first falling edge
of the current waveform that occurs after the
turn-off starts
SWLoss:TONEND Set or query a level on the first rising edge of
the voltage waveform that occurs after the
first falling edge
SWLoss:TOFFSTART Set or query a level on the falling edge of
the voltage waveform that defines where the
beginning of the switching loss measurement
ends
SWLoss:TONSTART Set or query a level on the falling edge of
the voltage waveform that defines where the
switching loss measurement begins
SWLoss:UNITs Set or query the units for Switching Loss
Measurement
SWLoss:VALue:CO NDUCTION? Return the power loss of the device under
test when the device is conducting in its on
state
SWLoss:VALue:TOTAL? Return the sum of the turn-on, turn-off, and
conduction switching losses
SWLoss:VALue:TURNO FF? Return the power loss of the device under
test when the device is transitioning between
its o n and off state
