Abstract:
1. A high frequency voltage probe comprising: a socket; a dielectric pin; a first layer of high-conductivity material that is in contact with a first portion of the dielectric pin, the first layer being configured to contact a test point in a device under test; a second layer of high-conductivity material that is in contact with a second portion of the dielectric pin; and a third layer of low-conductivity material that is in contact with a third portion of the dielectric pin; the third portion being located between the first portion and the second portion; the first layer and the second layer being in contact with the third layer; wherein a shaft comprises the second portion and the second layer; and wherein at least a portion of the shaft is located in the socket and is slidably removable from the socket; wherein the high frequency voltage probe is configured to be attached to a measurement and testing instrument (MTI) and to enable the MTI to determine a voltage level for a signal that is received by the high frequency voltage probe from the test point; and wherein the high frequency voltage probe is configured to enable the MTI to determine a voltage level for said signal with at least a 70% accuracy, said signal having a frequency of over 3 gigahertz.
