Semi-Rigid Test Probes Up to 6 GHz
-
Fairview Microwave’s semi-rigid test probe assemblies come in multiple cable diameters to help when attaching the unterminated end of the probe to a circuit board trace. There are two versions including straight-cut probe ends for those that would like to customize the dimensions of the center conductor and dielectric dimensions, as well as pre-stripped probe ends that are ready for immediate use. By soldering the outer conductor to the signal ground and the exposed center conductor to the trace carrying the signal of interest, simple sampling measurements can be made without having to create a separate subassembly circuit board or add a connector to the circuit layout which can take up valuable real estate. Fairview provides 3 diameters of semi-rigid coax and 3 different lengths from 3 inches to 12 inches to fit a variety of trace widths and applications. All test probes are 100% RF tested to ensure the cable assemblies operate to 6 GHz and also to make sure that the SMA connector interface meets the 1.35:1 VSWR specification prior to shipping. To protect the small diameter coax from damage, each part is shipped in a clear protective tube that can also be used for storing the probes for future use.
