The spectrum element embeds the spectrum display of a spectrum analyzer device in the screen. Actually, only the CSM-Spectrum-Analyzer device may be used with the spectrum element.
The spectrum element subscribes for a variety of parameter of the spectrum analyzer device to display its settings in the diagram area. It also permits to command some aspects of the spectrum analyzer device like the marker position. The spectrum data itself is read by subscribing for the 'trace' parameter of the device. This returns the spectrum data as a SpectrumTrace with each sweep of the spectrum analyzer. A complete description of the function of the spectrum element is given in a separate document.
