Patent ID: 8847616

Claim:
A measurement apparatus, the measurement apparatus comprising: a lid, wherein the lid comprises one or more penetrations through the lid; and a signal-conducting probe insertable through a penetration of the one or more penetrations, wherein the probe is removably affixed to the lid at the site of the penetration, and the probe comprises: a central conductive pin, wherein the central conductive pin transmits to a connection outside a case to which the lid is removably affixed a radio-frequency signal inductively received from a source inside the case, wherein the central conductive pin is dimensioned to extend at full insertion of the probe within an inductive signal transmission range of a test point on a circuit inside the case without touching the circuit; a dielectric region radially surrounding a portion of the central conductive pin, and a grounded outer conductive housing radially surrounding the dielectric region and electrically isolated from the central conductive pin by the dielectric region.
