National Instruments NI PCI-6552 用户手册

This section discusses what 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 

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 (NI 654X/655X Only)

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 using 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 using 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.
