CALCulate<Chn>:STATistics:RESult? MEAN | STDDev | MAX | MIN | RMS | PTPeak
|ELENgth | PDELay | ALL
Returns a single statistical parameters of the trace no. <Chn> or all parameters. It is not necessary to
display the info field (CALCulate<Chn>:STATistics[:STATe] ON) before using this command.
<Chn>
Channel number used to identify the active trace.
Parameters
MEAN – Return arithmetic mean value of all response values of the trace in the
entire sweep range (or in the evaluation range defined in manual control)
STDDev – Return standard deviation of all response values
MAX – Return the maximum of all response values
MIN – Return the minimum of all response values
RMS – Return the root mean square of all response values
PTPeak – Return the peak-to-peak value (MAX – MIN)
ELENgth – Return the electrical length
PDELay – Return the phase delay
ALL – Return all statistical values, observing the order used above
Range [def.
unit]
The data is returned as a comma-separated list of real numbers. The unit is the
default unit of the measured parameter; see
CALCulate<Ch>:PARameter:SDEFine but also depends on the trace format
(linear or logarithmic scale, see CALCulate<Chn>:FORMat). If a polar trace format
is selected, then the statistical parameters are calculated from the linear magnitude
of the measurement parameter. [–]
