Coaxial Probes

The Coaxial probe is the most efficient of all probe configurations and should be the first consideration in all applications. Analogous to the efficiency of modern, coaxial cable, coaxial probes allow almost unimpeded movement of the high frequency pulses throughout its length. The electromagnetic field that develops between the inner rod and outer tube is completely contained. The efficiency and sensitivity of a coaxial configuration yields robust signal strength even in extremely low dielectric (ƒÃr .1.4) applications. The sensitivity of this "closed" design, however, also makes it more susceptible to measurement error in applications of coating and buildup.
