This coupon type selection is available only for balanced ports on the
DUT. It is used for deembedding a balanced port when it is desired to
treat the single-ended legs of the port as uncoupled entities.
Figure 5-68: n uncoupled balanced input ports
This coupon type is available for DUTs with two or more single-ended
or balanced inputs (outputs). It is suitable for a multiport DUT with
coupled inputs (outputs) that have to be deembedded as a single

Coupled coupons are drawn with a brace to highlight the difference
