What Is the Cable Gauge for a Triaxial Cable?

Updated Nov 4, 2019

Reported In


  • PXIe-4139
  • Triaxial Cable

Issue Details

I have a PXIe-4139 with the SA-143T terminal block and the triaxial cable. I would like to know the cable's gauge to adapt its three terminals to my DUT that doesn't have an female triaxial plug.


The gauge of the triaxial cable that NI recommends for this application is 24 AWG.

Additional Information

It is not recommended to alter the triaxial cable in any way since it can add noise to the signal and the signal's integrity can be compromised.
