A "Single Shot" measurement is stopped after one statistics cycle, i.e. after the
number of measurement intervals defined by the "Statistic Count".
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 repetition modes for remote and manual control and the reset/preset
values are therefore independent from each other.

Control – Statistic Count
Defines the number of measurement intervals per measurement cycle (single shot
measurement); see Statistical Settings. This value is also relevant for continuous
measurements, because the averaging procedures depend on the statistic count; see
Statistical Results.
In the WiMAX multi-evaluation measurement, the measurement interval is completed
when the R&S CMW 500 has measured a burst and acquired a full set of
measurement results.

10.2.1.4 Multi Evaluation Configuration: Measurement Parameters
The "Measurement Parameters" specify the size of the measured uplink frame. The
settings must be in line with the received signal.
Multi Evaluation Configuration: Measurement Parameters
Measurement Parameters > Bandwidth
Selects the bandwidth of the measurement filter (IF filter). Set this parameter in
accordance with the channel bandwidth of the measured OFDMA signal.
GPIB command: CONFigure:WIMax:MEASurement<i>:MEValuation:BWIDth
Measurement Parameters > Link Mode
Selects the link and the sub-channel allocation mode. The R&S CMW 500 can analyze
UL signals with partial usage of sub-channels (UL-PUSC, Partially Used Sub-Carrier).
