User Manual 1173.9511.02 ─ 11
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.

CMW user manual, chapter "System Over-
view"
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.
Remote command:
Code Domain > Spreading Factor
Selects the spreading factor used to determine the CDP and CDE measurement
results (16, 32 or 64 codes).
Remote command:
Adjacent Channel Power
Enables either the ACP measurement at up to 10 offsets, or extended ACP measure-
ment at up to 20 offsets from the nominal carrier frequency. Each enabled frequency
offset corresponds to a symmetric pair of bars in the "Adjacent Channel Power (ACP)"
diagram in "Spectrum" view (see
chapter 5.2.7.4, "Multi Evaluation Detailed Views:
on page 732). Absolute ACP in dBm and the ACP in dBc relative to carrier
power can be displayed. The unit of measured ACP is selectable per frequency offset
(dBc or dBm). Additionally the resolution bandwidth is selectable per frequency offset.
