Example:
*RST; SWE:TYPE POW
Select a power sweep with default CW frequency and sweep range.
CALC:STAT:NLIN:COMP:LEV 2
Define a compression value of 2 dB.
CALC:STAT:NLIN:COMP:RES?
Query the compression point results <Cmp_In>, <Cmp_Out>. An
execution error message (error no. –200) is returned if no compression
point is found..
CALCulate<Ch/Tr>:STATistics:RESult? MEAN | STDDev | MAX | MIN | RMS |
PTPeak | ELENgth | PDELay | ALL
Returns a single statistical parameters of the trace no. <Ch/Tr> or all parameters. It is not necessary to
display the info field (CALCulate<Ch/Tr>:STATistics[:STATe] ON) before using this command.
<Ch/Tr>
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<Ch-
>Tr>:FORMat)
. If a polar trace format is selected, then the statistical
parameters are calculated from the linear magnitude of the
measurement parameter. [–]

Command
Types
Device-specific, query only.
Example:
*RST; CALC:STAT:RES? MAX
Calculate and return the maximum of the default trace showing an S-
parameter on a dB Mag scale.
:CALC:FORM POL; STAT:RES? MAX
Display the trace in a polar diagram and re-calculate the maximum. The
result corresponds to the previous result but is converted to a unitless
linear value.
