Commands Listed in Alphabetical Order
POWer:STATIs
tics (No Query Form)
Clears all the accumulated statistics of all measurements. Performs the same
function as the MEASUrement:STATIstics command.
Conditions
This command requires a DPO4PWR application module for 4000 series models,
or an MDO3PWR application module for MDO3000 series models.

Syntax
POWer:STATIstics {RESET}
Arguments
RESET clears the measurement statistics.
POWer:STATIstics:MODe
Enables or disables the display of the measurement statistics. Performs the same
function as the MEASUrement:STATIstics:MODe command.
Conditions
This command requires a DPO4PWR application modul
e for 4000 series models,

Syntax
POWer:STATIstics:MODe {OFF|ALL}
POWer:STATIstics:MODe?
Arguments
ALL turns on measurement statistics display.
OFF turns all measurements statistics off.
Examples
POWER:STATISTICS:MODE OFF turns measurements statistics display off.
POW
ER:STATISTICS:MODE?
might return :MEASUREMENT:STATISTICS:MODE
ALL
indicating that measurement statistics are turned on and all statistics are
being displayed for each measurement.

Power
Syntax
POWer:STATIstics:WEIghting <NR1>;Ranges {L,2,1000}
POWer:STATIstics:WEIghting?
Arguments
<NR1> is the number of samples used for the mean and standard deviation
statistical accumulations
Examples
POWER:STATISTICS:WEIGHTING 4 sets statistical weighting to four samples.
POWER:STATISTICS:WEIGHTING ? might return
:POWER:STATISTICS:WEIGHTING 4 indicating that statistics weighting is
currently set to 4 samples.
POWer:SWLoss:CONDCALCmethod
This command specifies the power application switching loss conduction
calculation method.
