PROBLEM TO BE SOLVED: To provide a device for measuring the antenna characteristics of a moving terminal capable of accurately measuring an antenna received field without being affected by a measuring system by using a light converting device instead of a coaxial cable. SOLUTION: This device for measuring antenna characteristics is provided with a laser diode 13 (light output means) embedded in a moving terminal 1 for converting a received field by an antenna mounted to the moving terminal 1 into optical energy, a photo diode 14 (light receiving means) provided separately from the moving terminal 1 to receive optical energy from the laser diode 13 via an optical cable 10 and to convert it into high-frequency energy, and a measuring device 9 such as a spectrum analyzer to measure the received field of the moving terminal 1 on the basis of the output of the light receiving means. |
