We just use a pth for the signal and another nearby for ground, and use a fast high-impedance (fet or sampling) probe.
How fast is the signal? Must the probe be a 50-ohm cable?
Oh, you can also just do the SMA pattern with tight holes and just sort of press in a connector temporarily.
Or use a permanent but cheaper surface-mount connector, like the Hirose things.

Hello Group Has anyone come across a PCB foil pattern which can accomodate a test probe for a coaxial type connection In other words something that would eliminate a SMA type connector for certain boards that fail and need to be probed. Using some sort of coaxial test probe. Thanks in advance
