The NI SMA-2164 test fixture is a breakout box for differential signals. This fixture
provides an easy way to connect to other devices for testing and debugging.
The following figure shows how to connect the differential DDC connector to the
NI SMA-2164, using the NI SHB12X-B12X cable. For more information about using
the NI SMA-2164, refer to the NI SMA-2164/2165 Test Fixture User Guide.

A flying lead cable, the NI SHB12X-H3X24, is also available for differential signals.
This cable offers connectivity similar to that found on a typical logic analyzer, so you
can use it in logic analyzer-type applications. This cable is shown in the following
figure.
