Abstract(in English) This paper describes an electro-optic (EO) handy probe for measuring high-speed signals in printed circuit boards (PCB's). The probe offers several unique features: 10-GHz bandwidth, ground-contactless measurement, ultrahigh input impedance (> 100 MΩ and < 0.2 pF), and no damage from electrostatic discharge. The probe has been successfully applied to waveform measurement of Gigabit per second digital IC on PCB, and eye diagrams at 1 Gbps. In addition, we demonstrate the measurement of resonance frequency of a loop antenna in contactless IC cards, and electric near field distribution radiated from a two-layer board. The results show that the probe system is a potential candidate for EMC/EMI instruments.
