The invention relates to a measuring device and a measurement method for the display of a measurement signal connected to the measuring device. The measuring device comprises a measurement-signal input, a measurement-parameter input, a calculation unit and a display unit for the display of calculated statistical signals. The measuring device is set up to display a plurality of statistical signals in parallel on the display unit in real-time.

Measuring device and measuring method with multiple display

A measuring device is used to increase a contrast of a plurality of measured values displayed in a spectrogram or spectral histogram and contains a data-acquisition unit, a computer unit and a statistic unit. The data-acquisition unit is embodied to detect a plurality of measured values to be displayed. The statistic unit is embodied to calculate a distribution which contains the frequency of occurrence for every level value of the measured values to be displayed. The computer unit is embodied to specify a dynamic range, over which the contrast extends. In this context, a specified proportion of the level values which image the noise are not used for the specification of the dynamic range.

Measuring device and method for automatic adjustment of contrast in the screen display

A method for measuring radio interference levels in a specific frequency range. Said method consists in adjusting the frequency range by means of a pre-measurement; respectively detecting, for each measuring frequency one measuring level of the signal which is to be measured; comparing the measured measuring level to the threshold value, characterized in that when the threshold value of the measuring level is exceeded, the measured level is compared to the respective measuring frequency as a radio interference level; and measuring, in a post-measurement phase, each characterized radio interference level in a more precise manner and in relation to the runtime performance thereof. The average frequency of the measuring frequency range of post-measurement, which is repeated in an alternating cyclic manner in relation to the post-measurement, is tracked in relation to the average frequency of the variable radio interference level which was recently determined in previous pre-measurement, for each characterized radio interference level
