Robust High Frequency Probe Omni Probe High Frequency Coaxial PCB Probe (44 GHz) For the high frequency PCB impedance characterization or high-speed electrical signal analysis the Omni probe by D-COAX is an excellent and affordable solution. High accuracy measurement obtained by having low contact resistance and impedance control of the probe throughout all transitions. Using Omni probe in conjunction with D-COAX probe holder, the device under test (DUT) can be tested not just in usual horizontal position, but can be tilted at the any angle or vertical position. The following are tips on using Omni probe.    Before making contact with a DUT, rotate the probe to correct position of the ground pins so that the signal will not be shorted to ground, use markings on the probe head for the ground pins. For accurate probe X-Y positioning, draw a circle with a sharpie with the aid of size 5/16” circle template around the desired contact location. Use microscope at about 45 degree angle to the DUT plane and use a circle as a visual aid to land the probe on the test pad. The Omni probe uses spring pins for all contacts. The best repeatable height for probe positioning is obtained by the following method: First, over travel the probe until the probe head surface touches the DUT surface, then raise it back 0.020 inches for the best repeatable results. The use of spring-loaded probe tips makes the probe last longer than conventional probes without losing performance or accuracy. The probe head has gold plated, rugged, crown tips that can be used for smooth or rough surfaces. Omni Probe www.d-coax.
