PROBLEM TO BE SOLVED: To provide a shared shield box which can perform the air measurement and coaxial cable measurement of a portable telephone terminal in the same shield box. SOLUTION: A measurement table 3 made of an insulating material is housed in a shield box 1 formed of a radio wave absorber 2. A portable telephone terminal 9 of the object of measurement is set at the location of the measurement coordinates on the measurement table 3. On the occasion of air measurement, an antenna 4 is set under the measurement table 3 and receives the radio waves emitted by the portable telephone terminals 9 and this output is measured by a measuring device through an electric supply line 5 and a connector 6 for air measurement. On the occasion of coaxial cable measurement, a connector 7 for coaxial cable measurement is set over the measurement table 3 and connected to the portable telephone terminal 9 with a coaxial cable, and this output is measured by a measuring device through the connector 7 for coaxial cable measurement disposed outside the shield box 1. An unassigned connector mounting cap 8 is attached on an unassigned terminal and the shield effect is maintained. |
