Magnitude Margin

For solutions in which convergence criteria for specific S-matrix entries were specified.

For each element in the S-matrix, the magnitude margin is the difference between the S-parameter delta magnitude and the target delta magnitude, which was specified in the Matrix Convergence dialog box. The magnitude margin reported under the Convergence tab is the maximum of these values over the entire matrix. The magnitude margin is defined as

(1)

where M_ij is the matrix convergence entry. It indicates the solution’s proximity to the target delta magnitude. If the solution has converged within the target delta magnitude, a value of zero will be reported for the pass.
