A flying lead cable, the NI SHB12X-H3X24, is also available for differential NI digital
waveform generator/analyzers (NI 656
x
). 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 11.

Creating a Custom Accessory
Many common NI digital waveform generator/analyzer applications may require you to create
a custom accessory to easily access the signals of your device under test (DUT). If you are
creating a custom accessory to use with a device with a VHDCI DDC connector, you can
purchase the mating connector for the VHDCI cable from NI. If you are designing a custom
accessory to use with a device that uses an Infiniband connector, you can also purchase this
connector. For more information about creating these custom accessories, refer to the
Interfacing to the NI Digital Waveform Generator/Analyzer using the VHDCI Connector
application note, available by entering
rdinwa
in the text field at
ni.com/info
. Refer to
Appendix A: Device Front Panels
for signal descriptions and pinout illustrations.
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.
