Cabling
Use an SHB12X-B12X cable for connections to the NI 656
x
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 654
x
/655

). For more
information about the NI CB-2162, refer to the
NI CB-2162 User Guide
