Commands Listed in Alphabetical Order
Arguments
CH1–CH4 sets an
analog channel as the current source.
REF1–REF4 sets a reference waveform as the current source.
Examples
POWER:CURRENTSOURCE CH1 sets the current source as CH1.
POWER:CURRENTSOURCE? might return POWER:CU RRENTSOURCE CH2 indicating
that CH2 is the current source.
POWer:DISplay
This command controls whether or not to display the power test results. Thisisthe
equivalent to pressing the Test button and then selecting the power application.
The same control is provided for each application.
Conditions
This command requires a DPO4PWR or a MDO3PWR application module.

POWer:DISplay {OFF|ON|0 |1}
POWer:DISplay?
Arguments
OFF or 0 turns off the display settings.
ON or 1 turns on the display settings.
Examples
POWER:DISPLAY 1 turns on the display.
POWER:DISPLAY? might return :PO WER:DISPLAY 0 indicating that the display
is off.
POWer:GATESOurce
This command specifies the gate source for the power application.
NOTE. This command is not applicable to 2-channel models. Any attempt to set
the
:GATESOurce
to other than
NONe
will not take effect.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:GATESOurce {CH1|CH2|CH3|CH4|REF1|REF2|REF3|REF4|NONe}
POWer:GATESOurce?
Arguments
CH1–CH4 sets an analog channel as the gate source.
REF1–REF4 sets a reference waveform as the gate source.
NONe is set when the gate source is not used in the application.
Examples
POWER:GATESOURCE CH1 sets the gated source as CH1.
POWER:GATESOURCE? might return POWER:GATESOURCE CH2 indicating that
CH2 is the gated source.
POWer:GATing
This command specifies the power application gating.
Conditions
This command requires a DPO4PWR application module for 4000 series models,

Syntax
POWer:GATing {OFF|SCRE en|CURSor}
POWer:GATing?
Arguments
OFF turns off measurement gating (full record).
SCREen turns on gating, using the left and right edges of the screen.
CURSor limits measurements to the portion of the waveform between the vertical
bar cursors, even if they are off screen.
Examples
POWER:GATING CURSOr sets cursor gating on the oscilloscope.
POWER:GATING? might return POWER:GATING OFF indicating that gating is
turned off on the oscilloscope.
