Abstract:
1. A method comprising: measuring, in every observation interval of a plurality of observation intervals, a short-term frequency of occurrence of signal levels of a test signal registered in each case within a signal-level range and at a value of time and/or frequency raster of a frequency of occurrence distribution, buffering, via at least one memory unit, the short-term frequency of occurrence distribution for display on a display device, determining, via at least one processor, after every observation interval with a frequency of occurrence being different from zero, for every signal-level and every value of the time and/or frequency raster of the frequency of occurrence distribution, a long-term statistical measurement parameter from all short-term frequencies of occurrence measured and buffered in earlier observation intervals and being different from zero, and displaying the long-term statistical parameter on the display device instead of the measured frequency of occurrence of signal levels within the signal-level range and at the value of the time and/or frequency raster, if no signal levels measured within the signal-level range and at the value of the time and/or frequency raster of the short-term frequency of occurrence distribution are counted within a current observation interval.
