Description

Applies (or disables) a fixture de-embedding setup to a TDR test setup. This is equivalent to clicking the Apply Fixture DeEmbed button in the TDR Setup dialog.

Fixture de-embedding setups are built by assigning Fixture Components to a DUT's ports. Fixture components are representations of real fixture hardware that is connected to a DUT port. The character of Fixture components are defined by imported S-parameters files. These files can be created from a TDR/TDT measurements performed on FlexDCA or some other source.

Each fixture component has a DUT port, which connects to the DUT, and a test port, which connects to the TDR head. Fixture components are named "A" through "P" in FlexDCA's GUI and are identified as FCOMA through FCOMP in remote commands. Once your fixture de-embedding setup is defined, it can be viewed in the Fixture De-Embedding Setup pane.

Performing a system default (:SYSTem:DEFault) deletes all DUT setups, deletes all fixture de-embedding components, deletes the current fixture de-embedding setup (if defined), and resets the default DUT 1 setup. To save your DUT, fixture components, and fixture setups, save an instrument state (:DISK:SETup:SAVe).

Before you can enable a fixture de-embedding setup, you must use the following commands to define the fixture de-embedding setup:

:TDR:DEEMbed:DUT:PORT:FIXTure associates a fixture component with a DUT port in the Fixture De-Embedding Setup pane. This command is also used to remove a fixture component.

:TDR:DEEMbed:DUT:PORT:DPORt associates a fixture port to be directly connected with the specified DUT's port.

:TDR:DEEMbed:DUT:PORT:TPORt associates a fixture port to be the test port for the specified DUT's port.
