Abstract

PURPOSE:To eliminate a cable and to prevent ringing, and to take measurement even when an IC to be observed and a measuring instrument are at distance by transmitting an electric signal detected by a stylus in the form of a radio wave. CONSTITUTION:A stylus 1 and an antenna 11 are fixed to a head 14, which incorporates a transmitter 10. Further, an antenna 12 is fixed to a box 15, which incorporates a receiver 13. The electric signal detected by the stylus 1 is converted by the transmitter 10 in the box 15 into the radio wave, which is transmitted from the antenna 11. This radio wave is received by the antenna 12 and demodulated by the receiver 13 in the box 15 into the electric signal, which is supplied to a synchroscope.
