5.4.2.2 Measurement Substates
Each running measurement can be in one of the following substates:
Substate Description
PENDing Waiting for resource allocation, adjustment, hardware switching
ADJusted All necessary adjustments finished, measurement running
INV No substate (invalid)
QUEued Measurement without resources, no results available
ACTive Resources allocated, acquisition of results in progress but not complete
INV No substate (invalid)
Querying substates
The main measurement state and the substates can be queried using
FETCh:<FWA>:<context>:STATe:ALL? where <FWA> denotes the firmware appli-
cation and <context> is to be replaced by the name of the measurement.
Example: FETCh:GPRF:MEAS<i>:POWer:STATe:ALL? (possible response: RUN,
ADJ, ACT).
5.4.2.3 Statistical Settings
Measurements generally cover a basic time interval and can be repeated periodically.
The measurement interval depends on the measurement context.
The number of measurement intervals that the R&S CMW500 repeats in order to calcu-
late statistical results is termed "statistic count" (multi-measurement count). After one
statistic count, the instrument has terminated a basic measurement cycle ("single-shot"
measurement). Measurement cycles can be repeated for an unlimited number of times,
resulting in the "continuous" repetition mode.
Most measurement contexts provide different sets of measurement results (single/scalar
values and traces) corresponding to the current measurement interval, and the maximum,
minimum, and average over a number of consecutive measurement intervals (see section
Statistical Results). In remote control these statistical results can be retrieved independ-
ently.
Statistic Count
Integer number of measurement intervals per measurement cycle (single-shot measure-
ment). The statistic count can be set independently for any measurement context or view;
see Measurement Contexts and Views.
CONFigure:<FWA>:<Context>:SCOunt:<View> <Count>
e.g. CONFigure:WIMax:MEASurement:MEValuation:SCOunt 10
(sets the statistic count for WiMAX "Multi Evaluation" measurements).
