The NI SMA-2164 test fixture is a breakout box for National Instruments
differential digital waveform generator/analyzer modules. This fixture
provides an easy way to connect to other devices for testing and debugging.
For more information about using the NI SMA-2164, refer to the
NI SMA-2164 User Guide.
Figure 7 shows how to connect a differential NI digital waveform
generator/analyzer to the NI SMA-2164, using the SHB 12X-B12X cable.
Figure 7.
Connecting the NI SMA-2164 Accessory
A flying lead cable, the NI SHB 12X-H3X24, is also available for differential
NI digital waveform generator/analyzers. This cable offers connectivity
similar to that found on a typical logic analyzer, so you can use it in logic
analyzer-type applications. The cable is shown in Figure 8.
