Installing Cables

The NI SHB12-B12X cable is designed to connect the NI SMA-2164 to the 
NI digital waveform generator/analyzer. Figure 2 shows how to install this 
cable.

Figure 2.  

Connecting a differential NI Digital Waveform 

Generator/Analyzer to the NI SMA-2164

Refer to Figure 2 as you complete the following steps to install the 
NI SHB12-B12X cable.

Caution

Disconnect power from the device, accessory, and any other connected hardware 

before connecting the cable to prevent damage to the hardware and personal injury. NI is 

not

 liable for damage resulting from improper connections.
