With the default value 0 Ts, the OFF power is measured over the evaluation period
defined by 3GPP. The leading value shifts the beginning of the evaluation period, the
lagging value shifts the end. Positive values decrease the evaluation period. Negative
values increase it.
This setting affects the measurement of PUCCH, PUSCH and SRS OFF powers.
Example, default period is one subframe with 20 µs exclusion at beginning:
Remote command:
Statistic Count
Defines the number of measurement intervals per measurement cycle for power meas-
urements. The following result views use this statistic count: power dynamics and
power monitor.
For power dynamics results, one measurement interval is completed when the
R&S
CMW has measured one complete diagram.
For power monitor results, one measurement interval is completed when the number of
subframes specified via parameter
has been captured.
Remote command:
High Dynamic Mode
Enables or disables the high dynamic mode.
The high dynamic mode is suitable for power dynamics measurements involving high
ON powers. In that case, the dynamic range of the R&S
CMW may not be sufficient to
measure both the high ON powers and the low OFF powers accurately.
In high dynamic mode, the dynamic range is increased by measuring the results in two
shots. One shot uses the configured settings to measure the ON power. The other shot
uses a lower "Expected Nominal Power" value to measure the OFF power results.
Disable the high dynamic mode to optimize the measurement speed, especially if you
are not interested in power dynamics results or if you measure low ON powers using a
low "Expected Nominal Power" setting.
While the combined signal path scenario is active, this parameter is not configurable.
