"Uncoupled"

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.

"Coupled"

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

unit.

Coupled coupons are drawn with a brace to highlight the difference

between coupled and uncoupled ports.

Remote command:

CALCulate:FMODel:DEASsistant<Ph_pt>:FIXTure:LEFT:TYPE

CALCulate:FMODel:DEASsistant:FIXTure:RIGHt:TYPE

CALCulate:FMODel:DEASsistant:PRESet

Use Same Coupon Left and Right

This control is only active, if you selected a two-sided DUT and the same coupon

model for the left and right side.

If checked, then in the measurement phase only the data of a single coupon ("Coupon

A") must be measured or loaded from file.

Remote command:

CALCulate:FMODel:DEASsistant:SAMCoupon

CALCulate:FMODel:DEASsistant:PRESet

Remove Active Deembedding

Use this button to remove the fixture deembedding and to deactivate all other deem-

bedding in the active channel (see"All Deembedding Activated" on page 624).

Note that the "Deembedding Assistant" works slightly different than the legacy Fixture

modeling dialog. In the "Deembedding Assistant", once applied, the deembedding

remains active until cleared or (partly) overwritten. The "Fixture Modeling" dialog resets

all deembedding files of a specific type (single-ended, balanced, port set), every time

you press the "Apply" button.
