Changes

The default computation frequency of the above observables is the project's center frequency (fc). You can change the observable frequency from the observable's property dialog and enter any frequency in Hz. The reason these types of simulation data are computed at a single frequency is their typically very large size. However, you can define as many instances of these observables and set different frequency values for each one. In the case of radiation pattern and RCS, there are two dialogs that can be accessed from the navigation tree. Right-click on the "Fer-Field Radiation Patterns" or "Radar Cross Sections" items of the navigation tree and select '''Insert Multi-Frequency Radiation Pattern...''' or '''Insert Multi-Frequency RCS...''' from the contextual menu.  <table><tr><td> [[Image:RadPattern multi.png|thumb|left|360px|EM.Tempo's Multi-frequency Radiation Pattern dialog.]] </td><td> [[Image:RCS multi.png|thumb|left|360px|EM.Tempo's Multi-frequency Radar Cross Section dialog.]] </td></tr></table> To facilitate the process of defining multi-frequency observables in EM.Tempo, you can use the following Python functions at the command line:
