Horizontal line for the labeled peak to be classified as a peak. Setting to peak threshold, which is illustrated by the red horizontal line. Than the Peak Excursion value for the labeled peak to be classified as a peak. Height differences between the labeled peak and its neighboring samples.
In the figure, the green vertical line illustrates the lesser of the two The peak excursion is the minimum difference between a peak sample and the samples to The peak threshold is a minimum value necessary for a sample value to be a If you change settings in the dsp.SpectrumAnalyzer interface, you can generate the corresponding command line settings to use later. You can change Spectrum Analyzer settings using menus and options in the interface of the scope, or by changing properties at the command line. There is enough data, rendering results correctly. When you clear this box, Spectrum Analyzer calculates spectra whenever To ensure that spectralĮstimates are as accurate as possible, clear the Reduce Plot Rate to Improve Therefore, Spectrum Analyzer does not render changes to the spectrum that occur andĮlapse between updates, which gives the impression of an incorrect spectrum. Spectrum Analyzer buffers the input signal data and only updates the display periodically at approximatelyĢ0 times per second. Signal, Spectrum Analyzer might display a stationary spectrum.
For example, if the input signal is wide-band with non-stationary behavior, such as a chirp When this option is selected, the Spectrum Analyzer may display a misleading spectrum in some Spectrum check box in the Trace options pane is enabled, and itsĮquivalent PlotAsTwoSidedSpectrum property is true, the Nyquist interval is, in hertz: In this case, the Spectrum Analyzer computes and plots the spectrum over Pane is enabled, and its equivalent FrequencySpan property is set to

Properties when the FrequencySpan property is set to 'Start andīy default, the Full Span check box in the Main options You can also get or set these values from the StartFrequency and Options pane, as given by the formula: f s p a n = f s t o p − f s t a r t. You can also get or set this value from theįrequencySpan property is set to 'Span and Center Frequency'.įrequency span value equals the difference of the įrequency span - The range of values shown on theįrequency-axis on the Spectrum Analyzer window.įrequency span value equals the Span parameter in From the Spectrum Analyzer menu, select View > Status Bar. You can choose to hide orĭisplay the entire status bar. Status bar in the Spectrum Analyzer window. The Display time indicator is a component of the However, that if the remaining data is not a complete window interval, the display is not
Ispectrum analyzer update#
Release method to update the display with any data left in the buffer. Loop that includes the Spectrum Analyzer, the times differ, you can call the True, the simulation time and display time might differ. Theĭisplay time is updated each time the display is updated. You can also set the sample rate using the SampleRate property. SampleRate parameter on the Main options pane of the At the beginning of a simulation, you can modify the T s i m = t s i m − 1 + l e n g t h ( 0 : l e n g t h ( x sin e ) ) − 1 S a m p l e R a t e
