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-Z5 transformer test fixture and test cables
The test fixture comes with four test leads equipped with alligator clips, to contact the
primary and secondary circuits of the measurement sample. The BNC connectors on
the right and left outside are intended to contact the circuit with the higher number of
windings. The two BNC connectors in the middle are intended for the circuit with lower
number of windings.
As an alternative, it is possible to install a user-specific test setup at the BNC connec-
tors directly.
6.1.6 BNC-to-BNC extension
The R&S LCX-Z11 BNC-to-BNC extension (1m) enables you to place the test setup in
the distance of 1 m from the site of the R&S LCX.
