摘要： The invention relates to an assembly for analyzing signals, comprising at least one central data processing unit and a screen unit (4) connected to the at least one central data processing unit, wherein the central data processing unit calculates a spectrum (31) and a spectrogram (30) from a digitalized signal. The at least one central data processing unit is designed such that same controls the screen unit (4) in such a way that the spectrogram (30) of the digitalized signal, the course of the spectrum (31) of the digitalized signal, and the course (32) of the digitalized signal present in the time range can be jointly displayed on the screen unit (4).

摘要： A "density trace" (730) is formed by measuring the density of each column of a frequency domain bitmap (720) above a user-specified "amplitude threshold" (725). The density of each column equals the sum of the densities of all of the pixels in the column that are above the amplitude threshold divided by the sum of the densities of all of the pixels in the column. A density trace (730) provides a convenient way to define and represent the occupancy for a large number of columns, and also allows density data to be quickly transmitted from one instrument or computer to another. In some embodiments, a density trace is incorporated into a trigger detector (700) of a test and measurement instrument and used to generate a trigger signal. The trigger detector compares the density trace (730) to a user-specified "density threshold" (735) and generates the trigger signal when the value of any point of the density trace violates the density threshold.

摘要： Das erfindungsgemäße Verfahren zur Messdatenverarbeitung mittels eines erfindungsgemäßen Messgeräts 10 weist die folgenden Schritte auf. Eine Mehrzahl von zeitlich aufeinanderfolgenden Einzelspektren eines Signals wird in einem bestimmten Zeitintervall und in einem gleichbleibenden Frequenzband mittels einer Messvorrichtung 12 gemessen. Die Häufigkeit des Auftretens eines jeden Spektralwertes wird aus der Gesamtheit der in dem bestimmten Zeitintervall gemessenen Einzelspektren mittels einer Akkumulationsvorrichtung 21 berechnet. Nur die Spektralwerte, die in einer ausgewählten Teilmenge der möglichen Auftrittshäufigkeiten der Spektralwerte liegen, werden mittels einer Filtervorrichtung 22 isoliert und auf einer Anzeigevorrichtung 15 dargestellt.

摘要： The invention relates to a method and a device for the determination of a statistical measurement value for all respective frequencies of a frequency distribution of signal levels from a measurement signal captured in several observation intervals. The device counts in each observation interval the frequency of the respective signal level range and the respective value of the time or frequency raster of the frequency distribution of the respective measured signal level of the measurement signals of new and stored data, in order to represent said data on an indicator system (2). After each observation interval for each signal level range and each value of time or frequency raster of the frequency distribution, the respective statistical measurement value from the respective newly buffered frequency and all measurement values in respective earlier observation intervals and buffered frequencies are determined and buffered.

摘要： Electric arc monitoring is effected by exploiting the discovery that electric arcs are fractal phenomena with all essential information that signifies "arc" contained in each fractal subset. These fractal subsets are logarithmically distributed over the arc spectrum. Monitoring of arcs is most advantageously effected on a fractal subset of low logarithmic order where the amplitude is higher pursuant to the 1/f characteristic of electric arcs (22), where cross-induction among neighboring circuits is lower, and where travel between the arc and the arc signature pickup (23) is longer than at the high frequencies customary for arc detection. Fractal subset transformation reduces the danger of false alarms. Arc signature portions may be processed in out of phase paths or treated as modulated carriers.

摘要： Display section (2) displays, on a screen, a zone marker for indicating, on a wide-band spectrum display area, that part of a wide-band spectrum which corresponds to a selected narrow-band spectrum to be displayed, and the wide-band spectrum, as well as said narrow-band spectrum which has been enlarged. First setting section (14) changes a center frequency or a band width of said displayed narrow-band spectrum, in accordance with the change of the position or width of the zone marker. Second setting section (15) cooperating with the first setting section (14) changes the position or width of the zone marker in accordance with the movement of the center frequency or band width of the displayed narrow-band spectrum. Control section (7h) for controlling a measurement resolution and a sweep time in accordance with the magnitude of the displayed spectrum, so as to satisfy the formula: sweep time ≧ band width/(measurement resolution)².K
where K = a constant.-
