Substate For main state Values Description
Resources RUN QUEued Measurement without resources, no results
available
RUN ACTive Resources allocated, acquisition of results in
progress but not complete
RDY or OFF 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).
6.4.2.3 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).
Repetition Mode
Single-shot: The measurement is stopped after the number of measurement intervals
defined by the "statistic count".
Continuous: The measurement is continued until it is stopped explicitly. Average results
are calculated according to the rules given in section Statistical Results.
