6 Measurement setups
Measuring components requires the use of suitable measurement adapters, referred to
as test fixtures.
6.1 About test fixtures
Test fixtures provide precise measurements of electronic components, such as passive
components, either with lead wires or SMD modules. They are designed to hold or
directly connect the measurement samples.
Frequency range
Some of the test fixtures are limited in frequency range. For details on the specifica-
tions, see the specifications document, section "Specifications" > "Options".

6.1.1 Test fixture for axial/radial lead type components
This test fixture R&S LCX-Z1 is a 4-terminal THT (through hole) test fixture for mea-
surements of both, axial or radial wired components.

LCX-Z1 test fixture for axial/radial lead type components
The R&S LCX-Z1 test adapter has two contact slots, each to plug in one lead of the
component. To perform short correction, connect the short circuit plate supplied with
the test fixture. For open correction, leave the slots unconnected.
The clamping jaws adapt to the wire diameter automatically.
6.1.2 Kelvin clip lead
The Kelvin clip lead R&S LCX-Z2 test fixture is designed for measuring components
with particular size, shape or terminals.

LCX-Z2 Kelvin clip lead
The test fixture is equipped with two insulated Kelvin clips that hold the wires or termi-
nals of the component. To perform a short correction, connect the clips together. For
open correction, leave the clips unconnected.
The cable positioning for R&S LCX-Z2 has an impact to measurement results, espe-
cially with higher frequencies.
6.1.3 Test fixture for SMD components
The R&S LCX-Z3 test fixture is designed for measuring SMD, i.e. leadless compo-
nents. It is suitable for rectangular or cylindrical shaped chips with parallel electrodes,
and components similar in shape and type.
