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.

LCX-Z3 SMD test fixture
The test fixture provides a section to position and center the component and clamp it
between two connection pins.
To perform a short correction, close the contacts of the connection pins. For open cor-
rection, use the lever to open the pins until the spacing between them corresponds
approximately to the length of the measurement sample. Hold this position during the
correction.
6.1.4 Test tweezers for SMD components
The test tweezers R&S LCX-Z4 test fixture is designed for measuring SMD compo-
nents, even when they are mounted on printed circuit boards. It provides simple and
fast contacting and is thus suitable, for example, for preselection during incoming
inspection or of small batches.

LCX-Z4 SMD test tweezers
The test fixture is equipped with tweezers, and miniature SMD tweezers.
To perform a short correction, hold the contacts of the tweezers closed. For open cor-
rection, leave the contacts open.
6.1.5 Test fixture with cables for transformer components
The transformer R&S LCX-Z5 test fixture is designed for measuring transformers or
transmitters in combination with transformers.
