Differential Matching Network

In contrast to standard balanced embedding (4-port), the matching circuit is only
applied to the differential mode port (2-port). It can be specified via a Touchstone s2p
file or by parametrizing a lumped "Shunt L, Shunt C" element model.

5.6.2.9

Fixture Modeling and Deembedding

When performing tasks such as verifying digital high-speed signal structures on printed
circuit boards (PCBs), measurements have to be carried out on certain layers without
the effects of probes, probe pads, vias, lead-ins and lead-outs. This requires the use of
accurate deembedding algorithms to calculate and remove these effects from the mea-
surements, leaving only the result for the area of interest.

Instead of asking the user to define the fixture by parametrizing one of the given lum-
ped circuit models or by "somehow" providing a suitable

snp

file, the firmware of the

R&S

ZNB/ZNBT now also provides integration for third-party tools that model the test

fixture from measured data:

The tools are integrated into the deembedding functionality of the analyzer firmware.

More fixture modeling tools may be added in future releases of the R&S
