CST2013: Signal Naming Conventions

录入:edatop.com     点击:

The signals calculated by the CST MICROWAVE STUDIO are named by the following conventions:

The substitutes P, Q, M and N are integer values, representing two ports (P,Q) and their corresponding modes (M,N). The general excitation string <Excitation> is then given by the following expressions, depending on a sequential or simultaneous port excitation (please see the Port Mode Excitation Selection dialog for more information.):

Sequential excitation

<Excitation> = P(N) :  excitation of the Nth mode of port P.

Simultaneous excitation

<Excitation> = P1(N1)[a1,p1],P2(N2)[a2,p2],...,[freq] : excitation of different port modes, combined with corresponding amplitudes and phase values (a,p) and finally the phase reference frequency (freq). The amplitude and phase values are referred to a reference signal with amplitude one (1/sqrt(watt)) and zero phase shift.

 

name

meaning

”i<Excitation>”

The input time signal of the chosen excitation.

”oQ(M)<Excitation>”

The output signal at port Q of mode M resulting from the chosen excitation.

”aQ(M)<Excitation>”

The amplitude of the scattering parameter (linear scale) SQP of mode M resulting from the chosen excitation.

”dQ(M)<Excitation>”

The amplitude of the scattering parameter (in decibel) SQP of mode M resulting from the chosen excitation.

”pQ(M)<Excitation>”

The phase of the scattering parameter (linear scale) SQP of mode M resulting from the chosen excitation.

 

All calculated Signals are stored in ASCII files. The names of these files are chosen according to the Result File Naming Conventions.
