etc.
Repetition The Repetition parameter defines how often the measurement is repeated:
Single Shot Single-shot measurement: the measurement is stopped after a
statistics cycle (or after a stop condition is met, see below). A
stopped measurement is indicated by the status display
HLT in
the Power softkey.
Unless otherwise stated, a statistics cycle corresponds to the
number of bursts/evaluation periods set under
Statistic Count .
Continuous Continuous measurement: The CMU continues the
measurement until it is terminated explicitly (or until the stop
condition for the measurement is met, see below). The
measurement results are valid after one statistics cycle;
however, the measurement is continued, and the output is
continuously updated. An ongoing measurement is indicated by
the status display
RUN in the softkey Power .
Single shot should be selected if only a single measurement result is required
under fixed conditions. The continuous measurement is suitable for monitoring the
evolution of a measured quantity in time, for example for adjustments.
Note: In remote mode, the counting measurement (counting mode) is
available as a further measurement mode with a defined number of
measurement cycles to be performed, see chapter 6 of this manual.

Stop Condition The Stop Condition field defines a stop condition for the measurement:
NONE Continue measurement irrespective of the results of the limit
check
On Limit Failure Stop measurement as soon as the limit check fails (one of the
tolerances is exceeded)

Display Mode The Display Mode field defines which of the four measured and calculated
measurement 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 all measured bursts
Maximum Maximum over all measured 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
performed statistics cycle.
