Repetition
Defines how often the measurement is repeated if it is not stopped explicitly or by a
failed limit check.
●
Continuous:
The measurement is continued until it is explicitly terminated; the
results are periodically updated.
●
Single-Shot:
The measurement is stopped after one statistics cycle.
Single-shot is preferable if only a single measurement result is required under fixed
conditions, which is typical for remote-controlled measurements. Continuous mode is
suitable for monitoring the evolution of the measurement results in time and observe
how they depend on the measurement configuration, which is typically done in manual
control. The reset/preset values therefore differ from each other.
Remote command:
CONFigure:EVDO:MEAS<i>:MEValuation:REPetition
Stop Condition
Specifies the conditions for an early termination of the measurement:
●
None:
The measurement is performed according to its "Repetition" mode and "Sta-
tistic Count", irrespective of the limit check results.
●
On Limit Failure:
The measurement is stopped as soon as one of the limits is
exceeded, irrespective of the repetition mode set. If no limit failure occurs, it is per-
formed according to its "Repetition" mode and "Statistic Count". Use this setting for
measurements that are essentially intended for checking limits, e.g. production
tests.
Remote command:
CONFigure:EVDO:MEAS<i>:MEValuation:SCONdition
Statistic Count Modulation / Spectrum
Defines the number of measurement intervals per measurement cycle (statistics cycle,
single-shot measurement). This value is also relevant for continuous measurements,
because the averaging procedures depend on the statistic count.
The measurement provides independent statistic counts for the modulation and spec-
trum results. In single-shot mode and with a shorter spectrum statistic count, the ACP
evaluation is stopped while the R&S
CMW continues providing new modulation results.

Remote command:
Measure on Exception
Specifies whether measurement results that the R&S
CMW identifies as faulty or inac-
curate are rejected. A faulty result occurs e.g. when an overload is detected. In remote
control, the cause of the error is indicated by the "reliability indicator".
●
Off:
Faulty results are rejected. The measurement is continued; the statistical
counters are not re-set. Use this mode to ensure that a single faulty result does not
affect the entire measurement.
