Of [[EM.Tempo]]'s frequency domain observables, the near fields, far fields and all of their associated parameters like directivity, RCS, etc., are calculated at a certain single frequency that is specified as part of the definition of the observable. To compute those frequency domain data at several frequencies, you need to define multiple observables, one for each frequency. On the other hand, port characteristics like S/Y/Z parameters and VSWR are calculated over the entire specified bandwidth of your project. Of [[EM.Tempo]]'s source types, lumped sources, waveguide sources and distributed sources let you define one or more ports for your physical structure and compute its port characteristics. One of [[EM.Tempo]]'s real advantages over frequency-domain solvers is its ability of generate wideband S/Z/Y parameter data in a single simulation run.
