7. Connecting Signals
This section discusses connections you can make to the device and how
to connect signals to the device for performing dynamic acquisition and
dynamic generation. For device front panel diagrams and connector
descriptions, refer to Appendix A: Device Front Panels.
Connecting Cables and Accessories
To make connections to the NI digital waveform generator/analyzer front
panel SMB jack connectors, use a shielded 50
Ω coaxial cable with an SMB
plug end.
Use an NI SHC68-C68-D2 cable for connections to the NI 654x/655x DDC
connector. The NI SHC68-C68-D2 is designed for single-ended, high-speed
digital signal transmission. The cable is shielded, with individual
microcoaxial 50
Ω lines for each signal.
Use an SHB12X-B12X cable for connections to the NI 656x DDC connector.
This cable is designed for differential, high-speed digital signal transmission.
Using Accessories
You have different accessory options based on whether you are using a
single-ended or differential NI digital waveform generator/analyzer.
Note Whether you use NI cables and accessories or design your
own, you should properly terminate cables to avoid improper
measurements due to signal reflections, overshoot, and undershoot.
Refer to the NI Digital Waveform Generator/Analyzer Help for more
information about signal termination.
Single-Ended Accessories
NI recommends using the NI CB-2162 single-ended digital I/O accessory to
access the signals on the 68-pin DDC connector and to terminate the
DIO channels. The NI CB-2162 also provides a platform for circuit
prototyping and DUT testing. The NI CB-2162 is specifically designed for
use with single-ended NI digital waveform generator/analyzers
(NI 654x/655x). For more information about the NI CB-2162, refer to
the NI CB-2162 User Guide.
NI also offers the NI SMB-2163 breakout box for National Instruments
single-ended digital waveform generator/analyzers. The NI SMB-2163 offers
coaxial SMB connectors for each channel on the DDC connector, providing
an easy way to connect to other devices for testing and debugging. For more
information about the NI SMB-2163, refer to the NI SMB-2163 User Guide.
Figures 4 and 5 show how to connect a single-ended NI digital waveform
generator/analyzer and the NI CB-2162 and NI SMB-2163, respectively,
using the NI SHC68-C68-D2 cable.
