●
Average:
Average of all "Current" values referenced to the last statistics cycle.
●
Min, Max:
Smallest or largest "Current" value that the R&S
CMW obtained since
the start of the measurement.
●
Max/Ext:
Largest or extreme "Current" value that the R&S
CMW obtained within
the measurement interval. For the error measurements (e.g. EVM, magnitude
error, phase error etc.) the extreme value is displayed (the biggest absolute value
with the correct sign).
Results for the waveform quality and EVM:
–
Remote command " ...:MAXimum?" for the objects with asymmetrical parame-
ters (e.g. waveform quality with the range 0 to 1 or EVM with the range 0% to
100%) queries the worst result.
–
Remote command "...:MINimum?" queries the best result, which is not relevant
therefore not displayed.
●
Std Dev:
Standard deviation of all "Current" values since the start of the measure-
ment.
All statistical results (statistical tables and "Average" or "Max" traces) are calculated
according to the general rules for statistical results.

Statistic Count
Progress bar for the measurement, displayed in all detailed views. During the first sin-
gle shot after the start of the measurement, the bar shows the number of elapsed mea-
surement intervals relative to the "Statistic Count". A filled progress bar indicates that
the first shot is complete and the statistical depth has been reached.
