Issue Details

I am assembling a new RF system or replacing cabling on an existing RF system using National Instruments devices. What cabling and connector types do I need for my devices? 


There are a number of cable types and connector types that can be implemented on National Instruments RF hardware. Generally 50 Ohm impedance flexible or semi-rigid cables are used with SMB, SMA, or BNC connections. This list is non-exhaustive and it is recommended that you consult the specifications sheet, getting started guide, and other supporting documentation for additional cabling considerations. Additionally, sections 2-5 of the Connectivity Options for RF Switch Applications White Paper cover these topics in more depth.

If the replacement cabling is for a cluster of devices that are sold as a single unit like the PXIe-5663 Vector Signal Generator or PXIe-5673 Vector Signal Analyzer, replacement cabling packages for these devices can be found under the Accessories section of the shop. For example, you should find Part Number Part Number 780566-01 (REPLACEMENT CABLE KIT, PXIE-5663/5663E) and Part Number 780567-01 (REPLACEMENT CABLE KIT, PXIE-5673/5673E) as accessories for the PXIe-5663 and PXIe-5673 correspondingly.

You can also Order By Part Number.

Additional Information

National Instruments sells a limited selection of individually packaged SMA cables. Refer to the shop for available accessories.
