Abstract
A measurement probe has housing in which are disposed a spring loaded coaxial probe assembly and a pressure sensor. The probe assembly is formed from a semi-rigid coaxial cable having a probing tip formed at one end and a coaxial connector at the other end. The pressure sensor has first electrically conductive contact secured and electrically coupled to the semi-rigid coaxial cable and a second electrically conductive contact positioned and secured within the internal cavity of the housing. The probing tip is coupled to electrical ground via a control module when the housing is in a first position and the probing tip is coupled to the input circuitry of the measurement test instrument via the control module in response to an activation signal generated by the pressure sensor in response to movement of the housing to a second position and coupled to the control module.
