For example, if the input signal is measured in volts, an m next to a measurement value indicates that this value is in units of millivolts.įor modifying the peak finder measurements programmatically, see the PeakFinderConfiguration (DSP System Toolbox) object. The letter after the value associated with each measurement indicates the abbreviation for the appropriate International System of Units (SI) prefix, such as m for milli. The peaks are valid for any units of the input signal. For more information on the algorithm, see the findpeaks (Signal Processing Toolbox) function. It does not consider end points as peaks. The Spectrum Analyzer algorithm defines a peak as a local maximum with lower values present on either side of the peak. You want the scope to detect peaks, the minimum distance between peaks, and label the To specify the number of peaks you want the scope to display, the minimum height above which The Peaks section in the Measurements tab allows you The Spectrum Analyzer computes peaks from the portion of the input signal that is currently on display in the scope, and the Peaks panel shows the peak values and the frequencies at which they occur. When you click on the Peak Finder button in the Measurements tab of the Spectrum Analyzer, an arrow appears on the plot at each maxima and a Peaks panel appears at the bottom of the scope window. To enable this parameter, select SpectrogramĬompute and display peak values in the scope display. Interpolation is used to obtain time resolution values thatĪre not integer multiples of 1/ RBW (Hz). Several spectral estimatesĪre combined into one spectrogram line to obtain the desired time Must be equal to or larger than the minimum attainable time resolutionĭefined by 1/ RBW (Hz). Resolution (s) to a positive value, then time resolution When you set RBW (Hz) to a positive scalar andĪnd the time resolution is set 1/ RBW (Hz) s. The main control and RBW is set to 1/ Time Resolution (s) to a positive scalar, then time resolution becomes Intervals in one frequency span and sets the time resolution is set to The Spectrum Analyzer adjusts the RBW value such that there are 1024 RBW The tooltipĭisplays the minimum attainable resolution given the current Spectrum Time it takes to compute a single spectral estimate. The minimum attainable resolution is the amount of Time resolution is the amount of data, in seconds, used to compute a Spectrum Analyzer with improved responsiveness and toolstrip interface in.Normalized Effective Noise Bandwidth (NENBW).Configuration > Spectrum Analyzer Settings ( ).
