Reviewing 2D Polar Plots

For a polar plot of S-parameters, Twin Builder displays this derived information about the cursor’s location in the lower-left corner :


MP

The magnitude and phase of the point.

RX

The normalized resistance (R) and reactance (X).

GB

An alternate view of the normalized resistance and reactance in the form of

where

  • G = conductance
  • B = susceptance

Q

The quality factor.

VSWR

The voltage standing wave ratio, calculated from the equation .

A scale below the plot displays the scale of points along the R-axis.
