For each list entry, you can configure a number of subframes and the expected nomi-
nal power applicable to these subframes. The resulting reference level is calculated
and displayed for information. The first entry is coupled to the standard expected nomi-
nal power setting, see
The list defines the expected nominal powers to be applied within one sequence of
measured subframes, configured via parameter
> No. of Sub-
frames.
Example:
●
configured "No. of Subframes" = 30, to be measured two times (defined via statistic
count)
●
list entry 0 = 10 subframes, 0 dBm
list entry 1 = 15 subframes, 10 dBm
list entry 2 = 10 subframes, 20 dBm
●
Resulting used expected nominal power:
measured subframe 1 to 10: entry 0, 0 dBm
measured subframe 11 to 25: entry 1, 10 dBm
measured subframe 26 to 30: entry 2, 20 dBm
second measurement of 30 subframes: again entry 0 to 2 are applied
If the configured number of subframes to be measured is longer than the sequence
defined via the list entries, the last list entry is used for the remaining subframes.
Note:
Between two list entries the R&S
CMW reconfigures the reference level accord-
ing to the next entry. This may impair the accuracy of measurement results for the pre-
ceding and the subsequent subframe. Consider this when configuring the measure-
ment and evaluating the results. Do not reconfigure the reference level directly before/
after the "Measure Subframe".
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.
●
On:
Results are never rejected. Use this mode e.g. for development purposes, if
you want to analyze the reason for occasional wrong transmissions.
