摘要： An electric signal measurement apparatus using the electro-optic sampling which is capable of measuring electric signals propagating on a signal line with only a lower disturbance, in a high precision over a wide bandwidth, and economically by a relatively compact apparatus size. The apparatus has a conductor body to be set in one point contact with the signal line, and an electro-optic material which changes a birefringence according to a strength of an electric field coupled by the conductor body, and which has a sufficient thickness between the lower surface and an upper surface such that a potential at the upper surface due to the electric field coupled by the conductor body is effectively zero. A polarization detector for detecting the laser beam with a polarization changed due to a change of the birefringence of the electro-optic material can be provided within a handy type probe body to which a probe head is attached.
