Repetition
The Repetition field determines the repetition mode. The basic evaluation period
(statistics cycle) corresponds to the evaluation of the trace over the entire time
range.
For more information see section Analyzer/Generator Configuration on p. 4.38 ff.
and section General Settings in Chapter 3.

Display Mode
The Display Mode field defines which of the four measured and calculated meas-
urement curves is displayed. The measurement curves differ in the way the burst
power p(t) at a fixed point in time t is calculated if the measurement extends over
several bursts:
Current Measured value for current burst
Minimum Minimum over a number of bursts
Maximum Maximum over a number of bursts
Average Average value over a number of bursts
The number of bursts for calculation of the statistical values Minimum, Maximum
and Average – and thus the result – depends on the repetition mode set. In detail,
this implies:
Single shot Display of minimum, maximum and average value from the per-
formed statistics cycle.
Continuous Display of minimum and maximum from all bursts already meas-
ured. The average value, however, is calculated according to
the rule in Chapter 3, section General Settings.
Remote control
no display mode set explicitly, the four measurement curves are accessible via
FETCh:ARRAy:POWer[:CURRent]? FETCh:ARRAy:POWer:MINimum?
FETCh:ARRAy:POWer:MAXimum? FETCh:ARRAy:POWer:AVERage? etc.
Statistic Count
Statistic Count defines how many sweeps are combined to form one statistics cy-
cle. Each sweep corresponds to the evaluation of the trace over the entire time
range.
1 to 1000 sweeps Number of sweeps per statistics cycle
The settings 1 and OFF (press ON/OFF key) are equivalent. A statistics cycle de-
termines the duration of single-shot measurements (see Chapter 3, section General
Settings).
