NI Digital Waveform Generator/Analyzer Getting Started Guide

Note

If you are designing a custom cabling solution with connector (779157-01) 

and the NI SHB12X-B12X cable (192344-01), the NI 656

x

 pinout is reversed at the 

end connector. Refer to Figure 18 for an illustration of the pinout at the end 
connector.

Wiring for Common Measurements

Dynamic generation and dynamic acquisition are two categories of applications that you can 
create for NI digital waveform generator/analyzers. This section provides information about the 
general wiring considerations for each type of application. Both examples use the NI 655

x

 and 

the NI CB-2162 for signal termination.

Dynamic Generation

When performing dynamic generation, an NI digital waveform generator/analyzer 
(NI 654

x

/655

x

) generates data through a matched impedance system that consists of a 50

 

output impedance, a 50

 cable, and a 50

 

accessory. Figure 12 shows a diagram of such a 

system, using the NI 655

x

 as an example. Depending on the loading of the peripheral device, you 

may need additional parallel termination resistance at the destination for optimal signal quality. 
Refer to the 

NI Digital Waveform Generator/Analyzer Help

 for more information about signal 

termination. 

Figure 12.

Dynamic Acquisition

When performing dynamic acquisition with the NI 654

x

/655

x

, the source generating the signals 

needs a matched source impedance as close to 50

 

as possible to minimize signal reflections 

and maintain optimal signal quality. Figure 13 shows a diagram of a dynamic acquisition system 
using the NI 655

x

 as an example.
