Subject: [SI-LIST] AW: plts fixture removal tool
We use adf and it usually wirks well (given a adequate test fixture). 3dB is a
sign of missing modes or wrong post assignment, is it a multilayer fixture?
Maybe the reference wasn't soldered correctly.

Betreff: [SI-LIST] plts fixture removal tool
We have 2equal(mirrored) fixtures soldered one to another.
I measured this structure with VNA and now i want to split s-parameter of 2
fixtures and get parameter of 1 fixture.
i tried to use plts fixture removal but i got strange results, new sparameter
starts from -3db.
somebody use this tool for such splitting?
is there other ways to do it? hspice, ads, hyperlynx ?
